Vehicle to Grid System Integration for Frequency Regulation of Renewable Based Microgrid

This work presents the role of vehicle to grid (V2G) integration in frequency regulation of renewable based microgrid. The renewable based micro grid is consisting of intermittent nature solar photovoltaic and wind sources; diesel power generator is taken as a backup power source along with residential and industrial load. Complete system is modelled and simulated in MATLAB/Simulink environment. Different types of vehicle profiles are considered for simulation purpose. Simulations are carried out for abnormal operating conditions such as partial shading of solar photovoltaic, discontinuation of wind farm power due to high wind speed and sudden change in load demand. Simulation results shows the effectiveness of V2G integration in power control and grid frequency regulation under abrupt conditions.
