Frequency Regulation by Electric Vehicle

Electric vehicles (EVs), connected to the grid, acts as a distributed load or distributed storage. Integration of EVs into microgrid is able to provide many services like ancillary services, active power control, reactive power compensation and specially frequency regulation. EVs with vehicle-to-grid (V2G) technology, provides frequency regulation service to overcome an infrequent generation of renewable sources and balances the load. This paper provides analysis of V2G technology for regulating the frequency of microgrid. The microgrid consists of different renewable energy sources, load and EV system. With different penetration level of EVs, frequency behavior of microgrid is analyzed. The results show that V2G technology is very effective in frequency regulation.
