ABSTRACT
This paper presents the economic analysis and perfect utilization of electrical energy in domestics and industrial consumers
and to send message to a single consumer for perfect time of utilisation so that each and every consumer will get electrical
energy . In this method the efficiency of distribution system can be increased. Smart grid encourages consumers to prefer
suitable energy in co operation with power grid at the most suitable time.
The main aim of this, is the load sharing and
minimize the stress on the distribution lines like Transformer , neighbor consumer etc. by motivating consumers to operate
only the most essential appliances at peak load periods and to transfer the operation of less needed appliances at off peak hours
when tariff may be lower. A case study has been developed to provide information to enable the user Mr. Krishna Murty who is
a LT consumer, The results and analysis which have been presented in this has been generated by a real time data collected for
mogulthur, Andhra pradesh .
Keywords:- Smart consumer, peak load, consumptions and appliances
1.INTRODUCTION
The smart energy information management system was developed with the ability to record, store and process power
consumption data of every major appliance in the domestic and industrial sector. The power consumption data is
accessible through the smart way like consumer energy portal, emails and handheld devices. Consumers can track their
power usage by device, room or appliance, which helps better regulate power consumption by analyzing minute wise,
half-hourly, hourly, daily and monthly and smart appliances, and automatically respond to increased demand in smart
grid. The case studies is developed for LT consumers, build complete power analysis, develop different types of reports
and save the power consumption amount by using power during off peak or mid peak. The TOU (Time of Use) Tariff is
used to reduce peak loads. The power analysis reports provide the deep insight into their consumption patterns like on
peak, off peak, mid peak and cost per appliances.
Appliances wise consumption for LT consumer
The following case study has been developed to provide information to enable the user to act. Mr. Krishna Murty is a
LT consumer and category is LT1-domestic . The below analysis provides deep insight for Mr.Krishna Murty to take
effective decisions
The consumers does not know about their
1) Daily energy consumption
2) Daily/hourly/half hourly/minute wise consumption
3) Which appliances are causing more energy consumption
4) How they can manage their consumption better
The below reports clearly demonstrates the net savings by the use of TOU tariffs and the designed reports like cost by
appliances.
Appliances wise consumption for LT consumer
For the LT consumers of Mogulturu circle we have consider Krishna Murty with service no.000017 . The data is
physically collected by appliances and analyzes the power consumption by appliance for Krishna Murty and provides
deep insight on overall consumption.

Total load of the particular consumer can depends on the below equation
LTotal required = LCW + LDI +LFC+LL+LR+LTC+LWH+LOther
(1)
Total unit consumed for the above load given by
UTotal = UCW+UDI+UFC+UL+UR+UTC+UWH+UOther
(2)
Total cost can be calculated by the equation
CT=CCW+CDI+CFC+CL+CR+CTC+CWH+COther

Monthly peak wise consumption for LT consumer
The consumer can visualize every month power consumption sliced into the MID PEAK,OFF PEAK and ON PEAK
and can perform what if analysis on moving from the on peak load to off peak load. it will be direct saving to
consumers in TOU Tariff and reduce the demand – supply mismatch. Krishna Murty Can login to consumer energy
portal and he can do the different types of analysis.

Daily- Month peak wise consumption for LT consumer
Daily data provides enough details for consumers to relate day- to- day activities to electricity usage.examples include
vacation days,holyday events,working days versus non working days,extreme weather days versus mild days and so on.
Only the days that are unusual stand out and those are the days the consumer care about.Krishna Murty Can login to

Hour wise consumption for LT customer
Hour wise consumption instantly knowing through consumer energy portal and also HAN automatically control the
power consumption with help of smart appliances. The consumer can visualize the load pattern of the power
consumption and take necessary action. Krishna Murty can logon to consumer’s energy portal and he can do the
different types of analysis.

TOU tariff calculation for LT consumer
Power companies charges consumers different prices for electricity on the basis of the time of use the electricity used so
that it will encourages consumers to shift some of their electricity uses to lower cost,non peak hours many consumers
able to reduce their electric bills and also reduce stress on the electricity generation and transmission infrastructure.
In the LT case study by seeing these reports he can able to shift the small amount of peak load into mid peak and half
peak and directly reduce the electricity bill in the TOU tariff compare to regular Tariff and in the following table will
provides the net savings to Krishna Murty.

2.CONCLUSION
It will reduce the demand supply mismatch, smart grids will be able to self heal, provide high reliability and power
quality, be resistant to cyber attacks, operate with muLTi-directional power flow, increase equipment utilization,
operate with lower cost and offer customers a variety of service choices. Smart appliances should be used in conjunction
with smart grid for reducing the peak demand. Real time information feedback regarding peak load conditions sent to
smart appliances at customer site. Reduced variability in consumption leads to lower breakdowns and lower operating
costs. The different types TOU tariff can be designed by analyzing the different load patterns. Master data
standardization can be developed for strong analysis.
