A smart grid is an electricity network based on digital technology that is used to supply electricity to consumers via two – way digital communication. This system allow for monitoring, analysis, control and communication within the supply chain to help improve efficiency, reduce energy consumption and cost and maximize reliability of the energy supply chain.

9. INTRODUCTION : Smart Grid
 A smart grid is an electricity network based on digital
technology that is used to supply electricity to consumers via
two – way digital communication.
 This system allow for monitoring, analysis, control and
communication within the supply chain to help improve
efficiency, reduce energy consumption and cost and maximize
reliability of the energy supply chain.

10. Comparison of existing grid vs smart grid
Existing Grid Smart grid
1. Electromechanical Digital
2. One - way communication Two – way communication
3. Centralized Generation Distributed Generation
4. Manual Monitoring Self Monitoring
5. Few Sensors Sensors throughout
6. Lack of control Robust control
7. Failure and blackout Adaptive and Islanding

11. Components of a smart grid :-
Smart meter
Phasor measurement
Information transfer
Distributed generation

12. Smart meter :-
 Will replace traditional meters
 Recognize and detail electrical consumption
 Power outage notification
 Transfer of information to central monitoring station
 Monitor time of the day consumption
 Power quality monitoring

13. Phasor Measurement :-
 Measure AC waveform
 Monitor power quality
 Wide area measurement system
 Communicate with central
monitoring system

14. Information Transfer :-
 Sensors or data
 Two way communication
 Low energy
 Fast startup time
 Mesh technology

15. Distributed Generation :-
 Allow small scale renewable generation
 Solar, wind, fuel cell, bio gas, microturbine
 Generation close to the load
 Better efficiency
 Increase Realibility

16. Benefits of a smart grid :-
 Efficiency
1. Distributed Generation
2. Smart metering
3. Energy measurement system
 Reliability
1. Wide area network
 Environmwnt
1. Renewable generation
2. Reduce demand on centralized generation facilities

17. Barriers :-
 Regulations
 Technological issues
 Large economic investment

18. Current implementation in India :-

19.  The National Smart Grid Mission was approved by the Indian Ministry of Power27
March 2015. Currently, it has allocated 14 smart grid pilot projects across India that
will be implemented by state-owned distribution utilities. They are in the initial phase
in their pilot project management timeline, finalizing budgets and contractors. Civil
work has started in few places and the government updates the progress monthly on
its website.
 The pilot projects sanctioned are being implemented across Assam, Gujarat, Himachal
Pradesh, Haryana, Karnataka, Punjab, Telangana, Tripura, Puducherry, Uttar Pradesh
and West Bengal, at a total cost of Rs 4.8 billion (including Rs 1.8 billion funding
support).
 These include a smart city demonstration project at the Indian Institute of Technology
(IT)-Kanpur campus and the Smart Grid Knowledge Centre being developed by Power
Grid Corporation of India Limited (Powergrid) in Manesar, Haryana All projects are
being partially funded by the MoP, except the project developed by Uttar Haryana Bijli
Vitran Nigam (UHBVN), which was funded by the New Energy and Industry
Technology Development Organisation (NEDO)

20.  Completed projects
In January 2018, UHBVN completed and inaugurated its smart grid
technology demonstration project in Panipat, with grant from Japan under
NEDO. The project entailed the installation of the SCADA system as well as
nearly 10,000 smart meters. The project demonstrated technology for the
reduction of aggregate technical and commercial losses and peak load, as
well as for monitoring and control of distribution lines.
 Projects at an advanced implementation stage
The Chamundeshwari Electricity Supply Company (CESC) pilot project at
Mysore is at an advanced Implementation stage with the installation of
21,824 smart meters and the commissioning of the associated distribution
control unit (DCUS), distribution transformer monitoring units (DTMUS) and
modems. Assam Power Distribution Company Limited’s (APDCL) project in
Paltan Bazaar covering 15,938 consumers is also at an advanced stage, and is
scheduled for completion Telangana State Southern Power Distribution
Company Limited’s (TSSPDCL) pilot project in the Jeedimetla industrial area,
covering about 11,904 consumers is also progressing at a fast pace.
