News- The Kerala State Electricity Board (KSEB) and the Indian Institute of Technology Bombay (IIT Bombay) have initiated a pilot project to explore the implementation of Vehicle-to-Grid (V2G) technology across the State.
About Vehicle-to-Grid (V2G) technology
- Vehicle-to-Grid (V2G) refers to a system where electric vehicles (EVs) are capable of sending electricity back to the power grid when not in use.
- When connected to a bi-directional charger, an idle EV acts as a decentralised battery energy storage device, supporting the distribution grid during peak demand or renewable energy (RE) variability.
- Types of Power Flow:
- Grid to Vehicle (G2V): The EV draws power from the grid and functions as a load.
- Vehicle to Grid (V2G): The EV discharges stored power to the grid and functions as a source.
- Benefits of V2G Technology:
- Enhances grid stability and supports RE integration.
- Enables demand response and reduces pressure on the grid.
- Uses tools like Time of Use (ToU) tariffs and smart charging to align EV charging with grid efficiency.
Global Scenario
- U.K., Netherlands, U.S. are actively piloting V2G systems.
- California uses V2G in ancillary service markets to enhance grid reliability.
V2G in India
- Still in the nascent stage.
- Focus is currently on EV charging infrastructure.
- The Central Electricity Authority (CEA) is preparing guidelines for reverse charging.
- Some DISCOMs have initiated pilot projects on V2G and smart charging.
