Integration of Electric Vehicles to DC microgrid Enabling V2G and G2V

Storage systems play an imperative role in asset utilization and optimization as backup power at peak load conditions in the emerging microgrid energy management. Electric vehicle (EV) batteries have the potential to be employed as energy storage devices depending on the surplus energy present in the system. Depending on the surplus energy and peak demand, it can work in both grid-to-vehicle (G2V) and vehicle-to-grid (V2G) modes. The implementation for the control is vital for proper operation of these modes. With a low-power solar panel, the DC-DC High Gain converters (HGC) will equip the requisite output for EV charging. This paper deals with the integration of PV, HGC, and EV to a common bus bar, where the Bidirectional inverter is connected to the utility Grid. Most of the EVs are parked for a long time in a day, which is considered an ideal asset. From this concept, retrieving the stored energy and giving it back to the grid, will help to reduce the consumption of fossil fuels during peak hours on the grid. Thus, it will also contribute more towards a green environment by reducing CO2 emissions. Based on demand and available PV power and battery power specific operation is performed, the Grid inverter control is developed in the PSCAD environment.
