6. 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

7. 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

8. 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

9. 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 having Indian companion standard
New type of interface
OBIS identifiers

10. Energy Meters AMR meters AMI – Automatic Meter Infrastructure
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

11. 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

12. 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)

13. 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

14. 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.
