Abstract:

This work emphasizes the utilization of plug-in electric vehicle as a backup power supply for residential loads in developing and underdeveloped countries as a part of the residential microgrid, without affecting its operation as an electric vehicle. The proposed V2H system also uses solar PV based charging of vehicle so that the whole system works as a nanogrid. The PEV is considered as a load of home when its batteries are charged by solar PV or grid. However, the main emphasis is given to utilize the solar energy to reduce charging from the grid. Both slow DC charging and fast DC charging are applied besides constant voltage and constant current charging modes during the daytime to harness and utilize more solar energy.

The main objectives of the proposed work are to minimize the energy cost of a household, to reduce the dependency on the grid, to enhance the reliability of power supply to residential loads during load shedding and blackouts, and to maximize the utilization of power produced by solar PV array mounted on rooftop.
