Vehicle to grid system for load and frequency management in smart grid

Growing worldwide interest towards alternative energy resources has proved that electric cars are the best alternative of conventional cars. A vast increase of electric cars production has been seen since 2010. Besides proving benefits to the viable growth and road efficiency, electric cars can be used to power utility systems and may provide benefits to car owners. Plugged in electric vehicle either behaves as a load or as an energy resource and this system is known as vehicle-to-grid (V2G). This paper evaluates the services that can be supplied to the consumers by main grid after V2G implantation. It has been analyzed that V2G concept used for frequency regulation in micro grid. This micro grid analysis consists of actual power generation, base load, peak load, EV aggregator and a mixture of renewable energy. For different levels of renewable energy generation in the grid, different scenarios are analyzed, by altering residential loads and EVs numbers. The results proved that V2G system can provide better frequency regulation in islanded grid scenarios.
