Foreword
It gives me immense pleasure to welcome you all to the 2nd international conference on
Power Generation Systems and Renewable Energy Technologies (PGSRET-2015)
being organized by the Faculty of Engineering and Technology, International Islamic
University Islamabad IIUI. The aim of the conference is to bring together scientist,
engineers, experts and academics from around the world in order to share and present
their ideas and scientific information on all topic related to the power generation and
renewable energies.
This time PGSRET received a total of 278 national and international research articles.
After a thorough and rigorous review process, only 82 high quality papers were
accepted that correspond to an acceptance rate of 29%. I am pleased to share that
scholars from more than 10 countries have opted this platform for presenting their
research and development work. Out of the total accepted papers, 15 presenters are
from other countries making the international contribution about 18%.
The success of PGSRET 2015 depends completely on the efforts, talent and the team
work of the organizing committee and their helpers who put much effort into planning
this event. In addition to their routine responsibilities, they work hard to take care of
everything starting from the call for paper till conducting the final proceeding of the
conference. Praise is also deserved for the external reviewers who invested significant
time in assessing, analyzing multiple papers to ensure the high standard of this
conference.
I would like to acknowledge the role of International Islamic University, Higher
Education Commission (HEC) Pakistan, IEEE Islamabad section, Habib Bank Limited

The cross section data is the primary requirement to carry-out multi-group calculations
for nuclear reactor design and analysis. The multi-group cross section data library is
generated for a Multipurpose Experimental Sodium Cooled Fast Reactor (MESOF). A
specific flux weighting spectra is used for point averaging the cross section obtained
from Evaluated Nuclear Data Files (ENDF/B-VII.0). A new group structure is formed
and well-known established procedure for nuclear data processing is adopted. The
multi-group
calculations
are performed using diffusion and transport theory based
codes for sodium cooled fast reactor with new and existing multi-group data libraries.
The calculations have shown improved results for multiplication factor.

Pakistan has been facing an acute energy crisis that affects public life and progress of
the country. Nuclear power being a safe, clean and reliable source of electricity has a
key significance to provide base-load electricity and minimizes the oil, gas and coal
imports. Therefore, national policy of Pakistan emphasizes to increase in nuclear share
from 800 MWe to 8800 MWe by 2030. The implementation of national policy leads to
the demand of skilled and qualified man power. To achieve the nuclear power targets in
the country, the availability of adequately qualified manpower is essential. Three
institutes Pakistan Institute of Engineering and Applied Sciences (PIEAS), Karachi
Institute of Power Engineering (KINPOE) and Chashma Centre for Nuclear Training
(CHASCENT) are providing sustainable nuclear education and training programs for
nuclear power sector. This paper highlights the nuclear education
programs
to
and
training
develop, enhance and maintain the skilled manpower for the national
nuclear power program at these institutes.

Radioactive Waste Analysis of CNPP-1 (PWR) Spent
Nuclear Fuel

2,3Pakistan Institute of Engineering and Applied Sciences, Islamabad.
Nuclear power is safe, reliable, environment friendly and large scale energy generating
technology. But it is also a fact that the public serious concern about the
management of radioactive waste is associated with this technology. The spent
nuclear fuel is being safely stored at nuclear power facilities for about 50 years. It has
not yet decided whether the used fuel is treated as a resource or waste.
About 96% of Uranium is still present in the fuel when it is removed from the reactor.
The spent fuel composition depends on the initial amount of fuel, irradiation time and
power of the reactor. This paper focuses to simulate the material composition,
radioactivity and its corresponding decay heat
profiles
of
the
CNPP-I using
depletion computer code ORIGEN-2. For this purpose irradiation model of the single
PWR fuel assembly (with 3% U-235 fuel enrichment) is developed for the period of
365 days. The simulated values of radioactivity of actinides, fission products and
activation products and their decay heat are compared with the analytical results
obtained from the Malbrain et al. Model.
This study shows that, nuclei heavier than uranium are obtained when uranium
captures one or several neutrons without fission. Thus, one finds almost 1% of
plutonium. Actinides other than plutonium (neptunium, americium, and curium) are
less abundant. About 3% of the mass consists of fission products of 235U and 239Pu.
The spent nuclear fuel decay heat comes mainly from unstable fission products,
unstable actinides, and activated structural and cladding materials. The main source of
decay heat production in spent nuclear fuel is the beta decay of fission products.

The main uses of the research reactor includes research and education, isotope
production, neutron activation analysis, neutron physics experiments and fundamental
research. Fuel loading in these reactors is smaller than the Nuclear Power Reactors. The
spent fuel is usually stored on-site for about ten years. During the storage their activity
and decay heat die down. The knowledge of spent fuel activity and decay heat is
essential for designing the spent fuel storage, its shielding, transportation and heat load
analysis. The decay heat and activity of spent fuel dictate the requirements for
reprocessing and disposal of generated radioactive waste. This paper presents the
radioactivity analysis of Pakistan Research Reactor –I (PARR- I) spent fuel. PARR-I
is MTR type research reactor utilizing 19.99% enriched Uranium Silicide (U3S2-Al)
fuel. It operates at 10 MW design power.
It highlights the activity and decay heat
profiles of actinides and fission products. The core inventory calculations were carried
out using depletion computer code ORIGEN2. The decay heat and activity profiles
show that the fission products dominate for initial period of decay as fuel is removed
from the core. The actinides activity and decay heat is smaller but they survive for a
longer time than fission products. The variation of decay heat with the passage of time
follow the same pattern as the activity.

In nuclear
industry,
RG58C/U cables are widely used in high radiation
environments. The incident gamma rays knock out electrons from cable core to
the outer
shield and hence, results in flow of current. Moreover, radiations also
induce conductivity
in the dielectric
resulting in an increase
current. The two processes cause a steady state radiation induced
in the leakage
current in the
coaxial cable. This radiation induced current degrades the actual signal from the
detector.
In this paper,
the initial
experimental results performed at Pakistan
Institute of Nuclear Science and Technology (PINSTECH) and Nuclear Medicine
Oncology and Radiotherapy Institute (NORI) are presented. It is observed that
radiation induced current has a prompt jump and then raises slowly to a saturation value
around 35 pA. RG58C/U coaxial cable was exposed to different dose rates and the
normalization factors were determined to be 4.66×10−14 Coul/rad.cm and 2.52×10−14
Coul/rad.cm for spent fuel element and Co-60 sources respectively.

High Purity Germanium (HPGe) radiation detec- tors are widely used for the gamma
ray spectroscopy due to their best energy resolution. However, the detector response
including Absolute Full Energy Peak (AFEP) efficiency, photo-fraction, Compton-tophoto ratio, etc., depends on the different physical parameters. The main advantage
of Monte Carlo simulations lies in the fact that we can separately study the
effect of different physical parameters. In this study, we present simulation results of
6
the HPGe detector using Electron Gamma Showers 5 (EGS5) code and compare the
simulation results with the already published data. A difference of about 5% was
observed when compared with MCNP simulation and experimental results. Finally, optimum value of the Lead shield thickness was determined to be 5 cm for
collimator diameter of 12 mm for different energies of interest.

Considering the world’s growing energy demand, the nuclear energy is an option to
meet this demand in a sustainable and reliable manner. The share of nuclear in the
global energy mix is continuously rising. This increase in share of nuclear is due to the
factors such as population growth, energy supply security, increased electricity demand,
climate mitigation and price volatility of fuels used for other sources of energy. In order
to meet this growing demand, large scale deployment of advanced nuclear reactors is
envisaged. This paper describes the advanced nuclear reactor technologies available for
immediate, near, and long term deployment. It also describes their innovative features
that make them safer, simpler and economically competitive with other technologies.
At the end, the author discusses their potential role within the context of Pakistan.

Pakistan is facing worst energy crises of its time. The total available hydro power
capacity is around 6500MW out of overall capacity of around 22500MW; potential
contributors of hydro power capacity are three projects Tarbela, Mangla and Ghazi
Barotha. The output of the hydro plants is subject to availability of water (optimum
level) in the dams, which can fall to as low as 2,500MW with substantial drop in water
level. Available resources are not sufficient to meet power demand for industry,
agriculture and ever increasing urban consumption. Currently electricity shortfall is of
the magnitude 5000MW. Water is considered to be an economic good because of
10
competing water use that in turn resulted in resource scarcity. This led the economies
for a desperate need of a policy to work out economic feasibility of water management.
Keeping in view the significance of inter relationship of hydro-economics, the aim of
this research is to compare the predicted economic benefits of Tarbela dam with actual
economic benefits attained since its commissioning. As we now have all the relevant
river inflows, rainfall data, the study will enable the policy makers to review the
feasibility reports and make appropriate decisions in future.

Fossil Fuels are considered the major sources to fulfill the world energy demand but
their harmful effect on our environment are the main source of concern .So it is the
need of time to utilize the such energy resources which are sustainable and environment
friendly. As we know that more than seventy percent portion of earth is covered by the
ocean. This source of energy is present in the form of ocean’s water, the air above the
ocean and the land beneath them. This paper presents a technique to extract the energy
from ocean waves using oscillating water column chamber and self -rectifying impulse
turbine. It also gives the brief introduction of oscillating water column used in the
extraction of wave energy. Designing of oscillating water column is accomplished
using Pro Engineer and CREO soft wares. The efficiency of this fabricated wave power
plant is 35% and the rpms of shaft are 200. The research in this area will provide
decentralized, sustainable and chemical emission free energy.

Solar energy can be used for various applications by solar photovoltaic and solar
thermal energy conversion technologies. However, being intermittent in nature, it
requires effective storage solution for utilization at night and during overcast
conditions. Solar pond having built in energy storage capacity is a promising solution.
In this paper, thermal analysis of salinity gradient solar pond in heat extraction mode is
presented. A theoretical model of a mini solar pond of 2 m2 surface area is developed.
Efficiency analysis in heat extraction mode is numerically performed through
MATLAB for a steady temperature difference of 300C across the non-convective zone
of solar pond under the climate conditions of Taxila, Pakistan. The analysis resulted
high efficiency of 22% with less conduction losses for a pond having increased depth
and thicker non-convective zone. Additionally, the analysis of different temperature
gradients across non-convective zone showed that the less temperature gradient resulted
high efficiency and less losses. These results established that the solar pond is suitable
for various applications and can be an effective solution for energy utilization and
storage in future

Statistical and computational models have been used worldwide by the researchers to
forecast time series. This paper implements two techniques; Autoregressive Integrated
Moving Average models and Neural Networks backpropagation algorithm to predict
wind speed time series for Gwadar, a coastal city of Balochistan. Based on the wind
speed forecast, power output has been estimated for a 50MW wind farm, choosing the
appropriate turbine and optimum hub elevation for the installation of wind turbine.
Furthermore, a financial study is presented of such a wind farm at Gwadar. For turbine
selection, 317 turbines of various ratings and manufacturers were surveyed through
software at different elevations - 60m, 80m, 100m and 120m. The results show that
Neural Networks capture the trend in the wind speed time series more accurately than
its statistical counterpart. Also, the optimum hub elevation for installing wind turbine at
Gwadar is found to be 100m. Annual energy production under these circumstances is
found to be 58.31 GWh/year.

Integration of different energy sources and power converters is required to meet the
load demands adequately under various natural conditions. This research work focuses
on the hybrid power system combining renewable energy sources, namely, a
photovoltaic (PV) array and a solid oxide fuel cell (SOFC) and a hybrid energy
storage system, i.e., a battery bank and hydrogen storage tanks in the proposed
architecture. The complete layout is connected to the national grid via power
electronics converters to enhance the continuity and reliability of power. In the
proposed system, the PV is taken as the primary energy source to satisfy the load

The widespread applications of plug-in hybrid electric vehicles (PHEVs) established
that there will be a massive inrush of PHEVs by the end of this century. There is a
rising risk that this anticipation in the number of PHEVs will impose an extra burden in
demand, especially at peak times and, therefore, threaten the stability of existing power
grids. To satisfy the additional load of PHEVs, a smart charging station (CS) facility
based on PV output power sensing due to the variation in solar irradiance and
temperature is presented in this paper. The power required to charge the PHEVs is
effectively managed from grid- connected photovoltaic (PV) generation. To confirm the
optimal utilization of available power, charging time and grid stability, five possible
switching modes have been considered for different interaction among the PHEVs,
PV and the grid. Simulation results confirm the effectiveness of the proposed CS
facility. The proposed CS and their controllers are designed in MATLAB/Simulink.

Many industrial loads suffer from various power quality problems like voltage sag and
swell, service outages etc. Due to these power quality issues industrial customer bears
huge financial loss. So in this situation static transfer switch can be the most cost
effective solution to avoid from these problems. Thyristor based Static transfer switch
is used to protect industrial load from these power quality problems by transferring
sensitive load from one source to another within minimum transfer time. This paper
investigates the performance of thyristor switches based STS system by improving the
power quality of a sensitive three-phase industrial load. Extensive simulations are
carried out to validate
the use of thyristor switches in medium voltage systems to
achieve a lesser transfer time in network reconfiguration. Performance analysis of
thyristor based STS system is carried out under various faults/disturbance conditions.
Simulation results obtained from MATLAB/Simulink verifies the performance of static
transfer switch.

Wind and solar based hybrid power systems are more feasible in areas with good
potential from both sources. These sources complement each other and allow autonomy
if one source is unavailable. Many remote villages of Pakistan are not electrified and
the current worsening energy crisis may not allow for these regions to be integrated
with the national grid. Even the areas connected to the grid undergo considerable power
16
cuts (as much as 16 hours a day) and there is a need to incorporate abundant
renewable energy to the electricity mix of the country. Therefore, a hybrid system
including grid, solar PV and wind energy would help eliminate load shedding [1].
However, costs of these systems must be limited to make them economically

This paper presents an analytical review of the repetitive control (RC) of micro grid
inverter. In grid connected inverter the focus is on current controlling rather than
voltage controlling. A plant is developed in Simulink to show the effect of different
control techniques. In this model, a DC to AC converter is connected to the grid source
with odd harmonics. To sink the output of converter with grid, an LCL filter has been
used. For controlling, two different techniques; Classical Control and RC have been
analyzed. The goal of such converter is to minimize the error between periodic
reference and output current in the presence of periodic disturbances. Reduction in
phase shift is also required to improve the power factor. The analysis also includes the
effect of different gains on the total harmonic distortion and the steady state error.

Unlike Si Thin film solar cells have appealed scientific community due to direct band
gap properties requiring less quantity of material. In thin film solar cells, CdTe and
CIGS are prominent candidates with PCE 17% and 20%, respectively. Large scale
production from CdTe and CIGS is limited due to unavailability of the elements (In,
Te) and environmental concerns with toxic Cd. Cu2ZnSnS4 (CZTS) has emerged as a
potential candidate in thin film photovoltaic due to its non-toxicity, low cost and
economic availability of precursors. CZTS is a semiconductor with a direct bandgap of
1.5 eV and an absorption coefficient of 104 cm-1. Conventional synthesis techniques
are either energy intensive or use toxic chemicals. In this work, Cu2ZnSnS4 was
successfully prepared by wet chemistry route using a non-toxic solvent. CZTS
precursor solution was prepared in a mixture of water and ethanol using metal chlorides
and Thiourea as source of sulfur. XRD analysis revealed that binary and ternary sulfide
phases formed at 250 °C. However, by increasing temperature up to 300 °C, pure CZTS
compound is formed with a change in lattice parameters. SEM studies of surface
morphology and particle size analyses were carried out. Furthermore, thermal behavior

electric utility companies. So the focus of utility companies has shifted towards
increased customer focus, enhanced performance and to provide reliable supply at low
cost. The electric power system must be operated in a way to schedule generations
economically of generation facilities. In last two decades many evolutionary techniques
has been developed to solve the optimization problems. Particle swarm optimization
has acquired much recognition due to less memory requirement and its inherent
simplicity. Particle swarm optimization technique proved to be having strong potential

plants are effectively penetrating in the existing power infrastructure to supply clean
energy to the end user. These sources can be utilized in Islanded or Grid connected
mode. Microgrid operation in Islanded mode is ideal for the locations where existing
grid infrastructure is unreachable or power quality is not up to the desired end user
level. Major concern of microgrid operation in islanded mode is control of active and
reactive power and complete power balance using electronic inverter interfaced
mechanism.
This paper presents survey on control techniques used to optimize,
Control, and enhance the power quality of Islanded microgrids. Operation of microgird
in islanded mode has been discussed whereas success stories and challenges faced
while implementing microgrid in different parts of the world has also been discussed in
the paper.

Electrical energy plays a vital role in the life of mankind due to extensive use of
electronic devices and electrical machinery. To provide green energy to user, renewable
energy got more importance. Conventionally, renewable energy was used in standalone
systems which need heavy capital investment along with high maintenance cost and
separate infra-structure. Meanwhile the trend has been changed and the grid tie
inverters got into the systems. There are many issues in finding a suitable grid tie
inverter because it needs high power inverters. The latest technique for inverter of high
power and low total harmonic distortion is Multilevel Inverter. There are many
inverters designing topologies of Multilevel Inverters. One of the most popular among
these topologies is Cascaded H-Bridge Multilevel Inverter. But this topology comes
with a limitation that it needs isolated DC voltage sources. In our research, we have
focused on the topology to overcome this issue in case when there is a single available
DC voltage source. Our research shows that this DC source can easily be split into a
number of isolated DC Sources as per desire by using less in system losses, small size
and weight of the converter. The design has been demonstrated by simulation and
verified by hardware implementation.

Renewable energy resources are the major demand of the day. As fossil fuels are
limited so we just can’t rely on them especially in this new age where the demand of
energy has increased drastically. Solar energy can be one of the effective renewable
energy sources. This is a new way of looking at a solar panel that we can generate
alternating current directly from photovoltaic cells. We can use an array of photovoltaic
cell pairs that are connected in anti-parallel form to create an AC wave form. Solar
panels today produce DC power which has to be firstly converted into AC to be mostly
used in business and home appliances. Solar panels become very expensive when we
add solar panel’s price joint with the price of inverters and phase synchronizers. In
addition to that the power losses of different components that are used in the DC to AC
converters so it becomes even more unappealing. We show a new technique for the
generation of AC power from Solar panel devoid of inverter. By adopting this
technique we can remove power losses due to an inverter. There is no need of batteries
in our technique so overall cost is also reduced. Another very good aspect of this
technique is that we get a very pure sine wave of better efficiency than that of an AC
inverter. We can generate the sine wave of any frequency by just controlling the speed
of motor used in this technique. So it is a very simple technique with great effects.

The demand for decreasing cost and volume and also for increasing efficiency leads to
a constantly increasing power density of converter systems. Many Electronic
applications could benefit from a power converter able to achieve high efficiency
across wide input and output voltage ranges. However, it is difficult for many
conventional power converter designs to provide wide operation range while
maintaining high efficiency and constantly increasing power density. High efficiency
series parallel resonant DC to DC converter is one which is applying on power
electronics equipment’s such as, telecom power supply, Mammography, computed
tomography, mobile equipment charger etc. For its high performance in telecom power
supply we intended to design and implement a prototype of this proposed [6] converter.
In this regard this paper contains the facts behind the choice of the resonant converter,
prototype design and design of gate drive circuit etc. with result and complements.

Glass fabric-reinforced polymer (GFRP) composites used in wind turbine blades are
usually exposed to large-deflection bending impacts caused by wind storms, heavy
rainfall, water splashes and hailstones in the offshore; and sand and dust impingement
in the desert environments. Such loadings can cause deterioration of structural integrity
and load-bearing capacity of the blade structure due to induced damage in the form of
matrix cracking, delamination and fibre fracture. These types of damage mechanisms
become more detrimental and pose a threat to the fatigue life of the turbine blades.
In this work, first the load-bearing and energy absorbing capability of woven GFRP
laminates is investigated under impact loading. Experimental tests are conducted to
characterise the behaviour of GFRP composites under large-deflection dynamic
bending in Izod type impact tests using Resil impactor. Impact tests are performed at
various energy levels to determine the ultimate fracture toughness of the laminates. In
these tests, the material demonstrated interply delamination damage due to weaker
matrix at low energy levels. At higher impact energies, apart from delamination, the
material also exhibited permanent deflection instead of catastrophic fabric fracture. The
latter was due to the visco-elasto-plastic nature of the glass fibres apart from the
thermoplastic matrix. The deformation behaviour and delamination damage ensued by
dynamic loading is also studied by developing three-dimensional finite element (FE)
model in Abaqus/Explicit commercial package. In FE model, multiple layers of bilinear
cohesive-zone elements are defined at the damage locations. Stress-based criteria and
fracture-mechanics techniques are used to assess damage initiation and its progression,
respectively. Numerical results gave good correlation when compared to the dynamic
response observed in experiments. The methodology developed here can be employed
in damage tolerant design of wind turbine composite blades subjected to similar impact
loading conditions.

Yttria Stabilized Zirconia (YSZ) is the most common thermal barrier coating material
with a temperature tolerance up to 1200°C above which it undergoes phase transitions
deteriorating its thermo-mechanical properties. Apart from YSZ, oxides having the
complex Magnetoplumbite structure such as LaMgAl11O19 are potential candidates for
even higher temperature applications due to their thermo-physical properties. In this
work, LaMgAl11O19 was synthesized through sol-gel citric acid method using nitrate
precursors. The powders were subjected to calcination treatment for 5 hours at 1000 °C,
1100 °C, 1200 °C, 1300 °C and 1400 °C. The microstructure was analyzed by XRD
and SEM techniques. XRD results identified a pure single phase of LaMgAl11O19,
obtained successfully at 1200 °C. Effects arising from changing calcination temperature
show that lattice strain reduced and crystallite size increased with increase in
temperature. SEM results revealed that the platelet structure of LaMgAl1O19 was
obtained which could increase thermal tolerance.

Statistical and computational models have been used worldwide by the researchers
to predict time series. This paper implements two techniques; Autoregressive Integrated
Moving Average models and Neural Networks backpropagation algorithm to predict
wind speed time series for Gwadar, a coastal city of Balochistan. Based on the wind
speed predict, power output has been estimated of a 50MW wind farm, choosing the
appropriate turbine and optimum hub elevation for the installation of wind turbine.
Furthermore, a financial study is presented of such a wind farm at Gwadar. For
turbine selection, 317 turbines of various ratings and manufacturers were surveyed
through software at different elevations - 60m, 80m, 100m and 120m. The results
show that Neural Networks capture the trend in the wind speed time series more
accurately than its statistical counterpart. Also, the optimum hub elevation for installing
wind turbine at Gwadar is found to be 100m. Annual energy production under these
circumstances is found to be 58.31 GWh/year.

Sugarcane bagasse, wheat straw and rice husk are amongst the most abundantly
available agriculture residues in Pakistan. Constant supply and huge quantities of these
residues make them favorable option to replace the fossil fuels. Thermal degradation of
these three samples was studied using TGA at three different heating rates of 5 °C min1, 20 °C min-1 and 40 °C min-1. The three samples were heated from 25 °C to 900 °C
and the influence of heating rate was investigated. Coats-Redfern method was applied
to calculate the apparent kinetic parameters. The results showed that the apparent
kinetic energy varies from 28.27 kJ mol-1 to 31.98 kJ mol-1, 38.39 kJ mol-1 to 70.22
kJ mol-1 and 25.05 kJ mol-1 to 30.42 kJ mol-1 for bagasse, wheat straw and rice husk
respectively. A clear linear fit was obtained using the Coats-Redfern method with
above 0.96 coefficient of regression for wheat straw and above 0.97 for sugarcane
bagasse and wheat straw respectively. For wheat straw at 40 °C min-1 heating rate and
for the first peak in DTG thermogram of sugarcane bagasse at 5 °C min-1, the order of
reaction was found to be 2.0 and for all three samples, order of reaction was found to be
0.5 for rest of the heating rates. Higher heating rates caused the lateral shift in the TGA
thermograms of all three biomass samples but the amount of residual char and ash
were unaffected. It was observed that the higher heating rate caused the sudden
release of volatile matter from the sample merging the different weight loss peaks, as
were evident at lower heating rate in the DTG thermogram of sugarcane bagasse. The
values of pre-exponential factor were found to be varied from 12.77-111.08 min-1,
117.92- 1.17x106 min-1 and 21.45 -5.92x104 min-1 for rice husk, wheat straw
and sugarcane bagasse respectively. For order of reaction of 0.5 at 20 °C min-1 heating

rate, three biomass samples can be arranged in terms of activation energy: wheat straw
> sugarcane bagasse > rice husk.

Electrical energy is a major necessity of every organization of world and the electrical
energy demand is increasing day by day. From past few decades, electricity is
generated centrally and then distributed over the whole areas of the country. But many
problems occur in centrally generated system like huge power loss in transmission line,
intermittent switching of load etc and another major issue arising from last few years is
severe load shedding in our country. Load shedding, a last stage solution of balancing
power generation and consumption, greatly affects the economy of any country because
economy is based upon industrial and commercial sector of any country and an
electrical power is backbone of any industry. Now a days, industries and other
organizations place their own local generation due to severe loadsheding. These
organizations and industries have some standby power to meet their future needs and
these local generations are in the form of renewable as well as nonrenewable sources,
also termed as distributed generation sources.
In this paper, we made an analysis for integration of different distributed generation
sources with existing distribution system feeder. For this we made a survey of some
selected organizations and collected data of their own total power production and
42
standby power. After this Electrical Transient Analysis Program (ETAP) software is
selected for analysis. Whole model of the distribution feeder and standby power is
designed in the software. These distributed generation sources (DGS) are then
integrated and fed into the power system. After successful completion of this whole
modeling, analysis process has done. Analysis of voltage profile, losses in the power
systems, reliability and at the end economic analysis and feasibility study is made. The
results of these analyses are discussed in detail in this paper.

change the role of system from passive to active but also show significant changes in
planning approach, distribution network operations and designing. Planning approach
that is being used for today’s distribution system can’t fulfill the integration method for
distributed generation and conventional system in an economical way because of the
fact that planners are not able to deal with complex environmental decisions and
lower development budgets for renewable. This review paper proposes the key facts

Pakistan suffers a continuous energy crisis and needs all out efforts to overcome this
problem. The use of locally available renewable energy and energy conservation offers
a viable solution to the energy crisis. As Pakistan consumes 50% of its primary energy
in the building sector, and therefore, it offers a huge potential for energy saving.
The study estimates the energy consumption in buildings as a function of heating and
cooling degree days for all climate zones of the country. Both components (weather
independent and dependent) of the energy used in buildings are calculated using
EnergyPlus software. Energy consumption is estimated both for conventional buildings
and buildings built approximately Building Energy Code of Pakistan (BECoP). The
results show a huge reduction in energy consumption in BECoP buildings. The paper
also demonstrates how to calculate energy consumption in houses in all zones of
Pakistan.

Cooperative routing is a cross-layer technique uti-lizing the benefits of cooperative
communication at physical layer and appropriate route selection at the network layer.
This reduces not only the power consumption but also the delay in the data transfer
between nodes. Cooperative routing is a potential scheme for lowering the effects of
channel fading and increasing the transmission energy efficiency in Wireless Sensor
Networks (WSNs). In this paper, a new protocol Cooperative Power and Energyefficient routing protocol (COPE) has been proposed and its performance has been
compared with Low Energy Adaptive Cluster (LEACH) and Power Efficient Gathering
in Sensor Information Systems (PEGASIS) routing protocols. The comparison is based
on performance metrics of energy efficiency, packet delivery ratio and throughput.
Simulations are conducted to validate the performance of COPE with that of two other

Jordan is a developing non-producing oil country; the major part of its needed
energy is imported from the neighboring countries in the forms of oil and gas, for
example, in year 2007 the demand for primary energy reached about 7438 million tons
of oil equivalent, with a growth rate 3.5 % which is 1.2% more than the year before and
is expected to be much more in the future due to the immigration from the neighboring
countries because of the war crisis in the neighboring countries. The cost of this
imported energy creates a heavy financial burden on the national economy which
reflects on the development plans and the standard living of the people. Therefore it is
of great necessity to look for utilizing other energy resources. Investigations and
research work carried out by universities staff and the National Energy Research Center
have shown evidence that Jordan has a potential geothermal source of energy which can
be utilized in producing heat and electricity.
In this paper Bouguer gravity data, obtained from a detailed gravity survey that was
conducted at the Zarqa Main Zara geothermal field, east of the Dead Sea, are evaluated
and combined with other previously obtained geophysical results including
aeromagnetic, deep seismic soundings and seismicity. The observed gravity data clearly
reflect the complex nature of the structural geology and tectonics of the study region. It
revealed the presence of a number of local and regional Bouguer anomalies with
different sizes, amplitudes and orientations. These anomalies are interpreted to have
been caused by subsurface basic to ultrabasic igneous intrusions located within the
uppermost part of the crust, mostly at depths 0.5km – 1.5km or shallower. With a
density 3.15 g/cm³ – 3.2 g/cm³, these have originated from the upper mantle. Travel
times of P and S-waves propagating through the study region indicate that some of the
subsurface bodies may be in a semi-solid state. The elevated temperature of the
geothermal springs of the study area is suggested to be caused by deep water circulation
that is facilitated by the permeability of the sedimentary and igneous rocks and both
47
local and regional faults. The hot igneous intrusions remain the major source of heating,
though normal geothermal gradient may add slightly to this heating process. The
temperatures of the water springs in Zarqa Main- Zara thermal springs are below the
boiling point; several applications are suggested to be utilized in the agricultural and
industrial fields. Finally, the binary thermodynamic cycle is suggested to utilize this
geothermal source in a power plant for generating electricity as the total flow of this
thermal water is 25X 10^6 m3/year with an average temperature of 50 degrees
centigrade. An approximate estimation of the output power is 3-4 Mega- Watt.

The people in Palestine are facing critical situation concerning the achievement of
reliable and sustainable energy. The absence of fossil fuel, the scarcity of conventional
energy resources and lack of a Palestinian infrastructure for about four decades due to
the continuous Israeli occupation had resulted in hindering the development of the
country. Palestine has to import all its needs of petroleum products and about 92% of
its needs of electrical energy from the Israeli Occupier. This resulted in continuous
deterioration of the development plans and also hindered the development initiatives.
Recent exploration of natural gas in Gaza Strip gives hopes and new opportunities for
gas industry in Palestine; these hopes are constrained by the Occupation. In spite
of all these challenges, Palestine has gone forward to utilize its natural resources for
rehabilitation and construction. In this study the possibility of utilizing the available
renewable energies in Palestine is taken into consideration, these include: wind, solar,
geothermal and biomass energies. Obstacles facing renewable energy development
were discussed in terms of Policy and politics obstacles, technical obstacles and social
obstacles. Suggested policies were proposed to overcome those obstacles,

as

the creation of a national fund, the development of governmental policies,
regulations,

Palestine is taken into consideration, its availability and practical applications, as a
source of renewable energy, which is identified by the reliability and sustainability. It
has been found that the Palestinians should depend on their own free energy,
geothermal energy has a notable role in reducing the residential energy consumption
especially for the heating and cooling purposes. Geothermal energy could also be used
to reduce the electrical bill that overloading the Palestinians shoulders by using low

Approach
Engr. Akhtar Saeed

Ea.saeed@dsu.edu.pk, akhtar_123@hotmail.com
Pakistan is facing an acute shortage of electricity power since former few decades. The
main reason behind the fact is that there has always been a lack of courtesy by the
policy and decision makers of the country towards enhancing the installed capacity of
the sector, as well as discovering other ways to implore the power from renewable
resources. Pakistan is an agricultural country whose economy is primarily based on the
agronomic yields, one of which is sugarcane – a cash crop. Thru the process of
extraction of sugar from the sugarcane, a stuff named Bagasse is leftover which has
been evidenced as a viable bio-fuel. Numerous countries across the globe are
consuming Bagasse to generate electricity, but regrettably in our country, this valued
51
renewable resource has mostly been thrown away as a mere trash. Keeping in view the
country's existing yield of Bagasse, Pakistan has an estimated capacity of about 3000
MW of electricity generation by its usage.
The rest of the paper is structured as follows: The first part involves a brief description
of Bagasse, its recent usage and significance as a bio-fuel across the globe. The second
part highlights its existing usage in Pakistan - stressing its importance. The third part
focuses the prospects of its consumption in the country, based on both the existing as
well as the projected outputs. In the concluding part, some recommendations are
underscored for its optimal usage to counter the electricity shortfall.

following paper presents a quantitative and analytical study on the current energy
situation of Pakistan, along with a methodology to reduce the gap. The paper
emphasizes the urge for a need to use energy models in order to forecast an increase in
demand. This can be achieved by using TIMES, a model which shows a detailed
relationship between energy commodities and the relevant processes required to
achieve those particular commodities. This methodology helps in developing an

The major factor influencing the feasibly of any power
generation
project
is
comparison of its production against the commodity or the energy utility it is
going to replace. In this case cost of energy is that parameter. As the trend shows
an increase in utility bills, continually increasing prices of energy will make
renewable and hybrid energy projects even more attractive. This paper describes the
effect of increase in prices of energy utilities (like electricity, natural gas) that can make
the project more feasible if considered during planning phase.

With increase of distributed generators (DG) in power system, there arise the potential
for operation of power system during islanding mode as well.
Along with its
advantages, there come challenges with protection system due to change in short circuit
current (which is the primary factor for overcurrent relay setting).
In this paper,
investigation of impact of Distributed Generators (DG) in protection system of the
distribution network has been carried out. Simulation based study regarding
protection issue during islanding condition has been carried out for distribution network
in mid Himmerland (Denmark). Use of definite time overcurrent relay along with
directional overcurrent relays has been proposed for the reliable protection scheme.
Simulation in ‘DIgSILENT Power Factory’ shows the proper selectivity and
53
coordination of overcurrent relays for 3 phase faults during various cases, such as
islanding or shutdown of some DG.

The basic aim of this work was to explore the possibilities of producing the bio-fuels by
green waste recycling from the available, inexpensive & echo-friendly resources. The
state of the art recovery of green energy from green waste & algal biomass was
explored with less energy intensive processes. Many different methods are in use to
produce bio fuels; however this new technique stands out among them due to its choice
of raw materials and processing. Mixing of residue algal biomass after extraction of oil
& green waste is suggested to prepare the feed for further extraction.
The lipid
extractor and Anaerobic Digester (AD) form the heart of this process. Bio-ethanol, biodiesel, omega 3 and astaxanthin will be extracted from micro-algae and while the
biogas will mainly result from AD. Bio-ethanol can be used in vehicle transportation,
bio-diesel can be blended with fossil diesel in a specific ratio to produce B20. The
omega 3 is an important supplement for human body metabolism while astaxanthin is
an antioxidant which is used on the skin to protect it from sunburn. Complex chemical
reactions take place in AD, resulting in the production of biogas that contains 50-60%
methane and 30-40% CO2 with traces of H2S, H2 and NH3.

To avoid blackouts in the energy system, the knowl- edge of the state of the power lines
has critical importance. To get the timely conscience, Phasor Measurement Units
(PMUs) are used to provide real-time synchronized measurements of voltage and
current phasors of the buses. The deployment of PMUs is done to first detect any single
or multiple line outage, and further to identify the correct line in outage. But if these
approaches are applied to more multiple line outages, the search space grows
exponentially. To reduce the computational complexity in case of multiple line outage
detection, stochastic optimization methods can be used. These methods give near
optimal solution with an acceptable computational complexity. In this paper, the use of
phasor angle measurements and optimal deployment of PMUs to identify multiple
power line outages is investigated. An adaptive version of estimation of distribution
algorithm (EDA) is proposed to detect and identify the lines in outage. In this adaptive
EDA thresholding technique is introduced in order to get better solutions. It is shown
that
the
proposed algorithm is achieving a better success rate than the other
evolutionary techniques.

As solar energy is a renewable energy that has the capacity to lessen the energy crisis in
the world, so there is a strong need to harvest and utilize this energy. Solar power is
readily available in the regions like UAE, South Asia, etc. so there is a strong need to
implement solar power harvesting techniques to lower the energy crisis. This paper
57
describes the simulation and implementation of a solar energy based MPPT battery
charger. The proposed design uses a microcontroller (Arduino Mega 2560 based upon
ATmega2560) that works on feedback from a PV panel and voltage of a battery, which
is to be charged, and controls the operation of a buck-boost DC-DC converter in order to
draw maximum power from the PV panel. Perturb and Observe algorithm is used to
operate the circuit at maximum power point irrespective of the present humidity,
temperature and irradiance conditions of the PV panel. The battery is used to store the
solar power so as to get energy when required and as per use i.e. if AC, then an inverter
can be connected after the battery and if DC, then a DC-DC converter can be used
according to need. The proposed design is simulated in MATLAB/Simulink and
implemented on hardware.

Non- Linear Analytic Approaches of Power Flow
Analysis and Voltage Profile Improvement
Raheel Muzzammel, Muhammad Ahsan, Waqas Ahmad
Department of Electrical Engineering, University of Lahore, Lahore, Pakistan
Power-flow analysis or load flow analysis is a numerical analysis of the flow of electric
power in an interconnected system. The goal of this analysis is to obtain complete
information of angle and magnitude of voltage for each bus in a power system for
specified load and generator real power and voltage conditions. Once the required
information is achieved, real and reactive power flow on each branch as well as
generator reactive power output can be analytically determined. Due to the nonlinear
nature of this problem, numerical methods are employed to obtain a solution within an
acceptable tolerance. In this paper, Gauss-Seidel, Newton-Raphson and FastDecoupled methods are compared with respect to their performances, convergence rates
and outputs for IEEE 14 bus system. Further, fact controllers i.e., static VAR
compensator for improvement in the voltage profile is also designed and implemented
and a comparison will also be drawn between the voltage profiles with or without the
absence of fact controllers.

The new Electronic ballast as a starting element has replaced the conservative ballast
system of fluorescent lamps. These highly efficient electronic ballasts are preferred
over conventional electromagnetic ballasts due to their excellent features, such as
weight reduction, increased efficiency in terms of light output and decreased flicker to a
large extent. This is particularly achieved by increasing the frequency of operation from
normal 50/60 Hz to 40 kHz, hence improving the lamp efficiency by approximately
10%. Numerous research studies are being conducted in order to reduce production
60
costs and to make the electronic ballasts a more attractive alternative. The dimming
control capacity in electronic ballasts for fluorescent lamps has been quickly increased
due to high potential of energy saving and the comfort to users but has new challenges
in the design of electronic ballast.

Residential sector constitutes major portion of electricity market and majority of the
worldwide consumers are not able to interact with grid dynamically according to
fluctuating conditions. Smart Grid is proposed to overcome the shortcomings of the
existing grid with integrated bidirectional communication and control infrastructure
including dynamic Demand Side Management (DSM). This paper presents a detailed
review of the DSM and its applications for flattening of load curve and reduction of the
peak to average ratio. The paper reviews the optimization techniques used in smart
homes at individual user level and cooperative DSM for optimal usage of electricity.
For optimization purpose, the residential consumers are mostly treated at individual
level and work on the cooperative DSM, also known as community base DSM, is in
initial stages and has great potential of research. In traditional DSM, consumers actions
are not coordinated but in cooperative optimization the DSM is applied for entire
community. Comparison between individual DSM and cooperative DSM optimization
techniques has also been added

Our country is facing immense energy deficit, local businesses and industries
operating in day time such as steel, clothing, and groceries are getting affected. All
these sectors need some reliable and low cost alternative power generation systems
other than the conventional ones that can provide them power in day time because most
of the industries production takes place in the day time. The idea is to provide
renewable energy power system, but currently the renewable energy systems available
in market requires a large amount for capital investment and their maintenance after a
year or two because of batteries being used in it. Thus renewable energy power
system
which
does
not contains batteries has very low maintenance cost in
long-run, suggested system is a battery less MPPT based voltage regulator that
be

The objective of this paper is to verify the steady state analysis of PARR-I using CFD
code in Fluent, compare its result with 1-Dimensional code and to study the
hypothetical accidental case of flow blockage in one of its coolant channel. Pakistan
Research Reactor (PARR-I) is a pool type research reactor with peak thermal power of
62
10 MW. Three dimensional steady state thermal hydraulic analysis for average as well
as hot channel had been performed. Key parameters of flow have been calculated using
different turbulence models. For comparison, outputs have been compared with the data
available in First Safety Analysis Report (FSAR) of PARR-I. Range of variations in
results of each of these turbulence models have been compared with literature. This
helped in selecting the final model and grid for steady state thermal hydraulic analysis.
Buckling in average as well as hot channel has been applied on the selected grid for
both average and hot channel conditions. Three case studies of buckling have been
considered with 50%, 75%, and 95 % blockage to the coolant flow. Clad temperatures,
bulk temperature rise and increase in pressure drop are computed and integrity of core
has been computed.

Maintain a perfect sine wave voltage and constant magnitude is really challenging,
due to different aspects like the load unbalance, distribution line impedance, poor
power factor, non-linear loads etc. Increase in the usage of the semiconductor
devices in the appliances that are used in the consumer level as well as industrial
level is distorting the voltage quality. Some of the major voltage quality issues that are
faced by the utility as well as the consumer are discussed. Those voltage quality issues
have deleterious effect on the customer appliances, and make them prone to failures.
These failures monetarily affect the consumers that have sensitive equipment.
Different mitigated solutions are proposed to improve the voltage value fluctuations.
The paper mainly covers the different reasons of the voltage value distortions that are
caused by the different aspects, starting from the distribution network constraints to
the faults that are very common in the low voltage system. The voltage quality
problems that are severe from customer point of view are:
-voltage magnitude variation
-voltage sags
-voltage harmonics

The most important commodities in our life are energy and water. Many techniques
were used to save water and energy, including water recycling, energy recovery and
energy efficient devices. In this study the effect of using a cover on the cold water inlet
of hot water storage tank with a discrete usage type was investigated experimentally.
The selected flow rate was 8 lpm and the waiting periods were 5, 10, and 15
min respectively. The temperature distribution through the tank, and temperature
stratification were achieved and analyzed. A positive influence of using a covered inlet
on saving higher amounts of hot water was observed. It has been found that using a
suitable cover on the cold water inlet reduces the turbulent mixing in the hot water
storage tank, thus saving much of the hot water within the tank for later usage. Most of
the cold water was accumulated at the bottom side which increases the efficiency of the
solar collectors when used. The best waiting period was 10 minutes under the
experiment circumstances, this result is not absolute, and more investigations regarding
the water flow rate and the waiting periods should be done.
