Main focus of conference
• Transmission, Distribution & Metering
• Technology upgradation
• Renewable Energy Sources
• Smart Metering
• Advanced Metering Infrastructure
•
•
•
•
•
•
Dynamic Distribution Networks
Generation Portfolio
Demand Side Management
Energy Efficiency
Developments to improve Grid connectivity
Business Opportunities
6
Smart Grid & Smart Meters
• Basic requirements
– Grid management (SCADA)
– Grid Energy Management (upto DT)
• HT Technical loss evaluation
–
–
–
–
–
–
Management of distribution network
Automated metering infrastructure (AMI)
Consumer Energy management
Demand side management
Transformer load management
Consumer Services
• Same system can be used for Water and Gas
networks
7
Smart Grid
• Traditional Power Grid need upgradetion to meet prompt consumer
services, Increase of Power demand, Higher reliability and quality
power
• Smart Grid is a vision of a better electricity delivery inftrastructure.
• Requirements:
–
–
–
–
–
Different sources of power generation connection to Grid
Centralised and Distributed generating stations connection to Grid
Integrated Grid network
To meet peak demand
Distributed Energy Resource (DER) integration with the Grid
• It needs effective regulatory frameworks to deploy smart metering
and smart grid programmes.
• Smart metering, AMI, automated distribution, grid security,
interoperability etc
8
Energy Meters
• Different types of Energy meters available but
not having common data communication media
(i.e. common protocol)
• Use of DLMS / COSEM meters - Three phase
are the requirement in RAPDRP
– DLMS: Device language message specification
– Standard: IEC 62056 having Indian companion
standard
– New type of interface
– OBIS identifiers
9
Energy Meters
• AMR meters
– Reduction of Expenses
– Increase of Income
– Improvement of Customer Services
• AMI – Automatic Meter Infrastructure
– Consumer meters, intermediate communication
meters, data concentrator, GPRS, server and its
software
– Metering, Billing, remote meter connect/disconnect,
Energy audit, report generation
• Smart Meters
– Two way communication facility and programmable
10
Meter Interoperability
• MIOS – Meter inter-operability solution
– IEEMA Meter Division has promoted this Forum
called MIOS
– Objective to provide possible way forward by the
metering companies so that utilities can use common
IT infrastructure to gather information from meters of
all makes to ensure vendor independent integration of
meter data for their business processes through
interoperability.
– API – Application Programme Interface
• All meter manufacturers have to give API complying to
specifications and they can continue their existing Protocols
11
Smart Grid
• Smart grids presents
–
–
–
–
–
–
–
growth in economy
Reduction of Expenses
Reduction of Energy Losses
Better load management
Smart appliances
Controlling of supply
Remote monitoring of network
• AHAM (Association of Home Appliance Manufacturers)
have completed technical evaluation and assessment of
communications standards for smart appliances
• The Dutch association of energy network operators
(Netbeheer Nederland) has released privacy and
security requirements for the country’s advanced
metering infrastructure (AMI)
12
• DLMS: Device language message specification
– A Guideline paper issued by CPRI, Banglore for “Data
Exchange for Electricity Meter Reading, Tariff and Load
Control: A companion specification.
• IDIS: Interoperable device interface specifications
• DLC: Distribution Line Carrier communications
protocol
– has been implemented as part of smart metering and
smart grid solutions at a number of utilities including
Energie AG in Austria, Arbon Energie in Switzerland
and EnBW Ostwürttemberg Donau Ries AG (EnBW
ODR) in Germany
13
UGVCL experience
• 100% AMR used in HT consumers and introducing upto
50KW load LT Industrial consumers.
• Implemented e-Urja ERP solution upto sub-division level
• IT implemented and capable to take benefit of Smart grid
system
• Undertaken one pilot project of AMI at our Kalol Division
– Software and equipments were provided by SPML, Hydrabad
– Consumer meter not removed. Its accuracy compared with
series interface meter
– LT side PLC communication used
– HT side GPRS communication used
– Data concentrator fixed on DT
– Server at SPML centre being pilot project
– From any offices you can see the online data and reports
– It helps a lot to improve the system in short duration without trial.
