The Department of Electrical and Electronics Engineering, School of Engineering, Amrita Vishwa Vidyapeetham, Coimbatore, conducted a Lecture on Smart Grid on March 30, 2016.
Electricity is the most versatile and widely used form of energy and global demand is growing continuously. The electrical power system was built up over more than 100 years. It is now one of the most effective components of the infrastructure on which modern society depends. It delivers electrical energy to industry, commercial and residential consumers, meeting ever-growing demand. A smart grid is an evolved grid system that manages electricity demand in a sustainable, reliable and economic manner, built on advanced infrastructure and tuned to facilitate the integration of all involved.
A shift from a centralized generation to a decentralize generation is happening. The traditional boundaries between generation, transmission and distribution are fast disappearing and the grid is evolving into an integrated smart grid, a unique solution which integrates all type of power generation and helps the consumer becomes a producer and consumer (prosumer). Each household will be able to generate and store electricity for its own use or sell it to the grid. Smart grid technologies can empower customers with real-time control and the choice to generate, store and consume electricity at the lowest cost available or sell it to the grid during the surplus generation while ensuring high quality and availability of power. With the help of programs like demand response (DR), customers can change their consumption patterns by shifting their consumption from expensive peak hours to cheaper off-peak hours making the power flow more interactive, efficient, more environment and customer friendly. “Smart grid is an electricity grid with communication, automation and IT systems that enable real-time monitoring and control of bi-directional power flows and information flows from points of generation to points of consumption at the appliances level.”
Key drivers for smart grids for different stakeholders such as utilities and customers in the Indian context are:
Utilities can have Reduction in Aggregate Technical and Commercial (AT&C) losses, Peak-load management – multiple options from direct load control to price incentives to customers, Reduction in power purchase cost, Better asset management, Increased grid visibility, Self-healing grid- faster restoration of electricity after fault or disturbances, and Renewable energy integration. Whereas the customer can have 24x7 Power for All, improved reliability of supply to all customers – no power cuts, no more DG sets and inverters for back up, Improved quality of supply – no more voltage stabilizers, User-friendly and transparent interface with utilities, Increased choice for customers – including green power, “Prosumer” enablement – can produce own electricity and consume or sell, and Options to save money by shifting loads from peak hours to off-peak periods
This talk introduces the components of the smart grid in generation, transmission and distribution.
