Abstract
Electric vehicles (EV) can be used as not only transportation equipment but also energy storage and leveling of renewable energy generated fluctuations by using EV batteries. In this paper, an advanced V2H(Vehicle to Home) system which is combined with photovoltaic power generator (PV), EV and heat pump (HP) water heater has been studied in order to use renewable energy effectively. In this system, PV power is charged directly to EV battery and surplus electricity that is not used for driving the car is supplied from EV battery to the home. As a result, the advanced V2H system is able to reduce CO2 emissions by 80% in comparison with the conventional system. And, it is clarified that the V2H system can utilize PV power more efficiently than the mega-solar system in which EV is charged from power system. Additionally, EV battery can be used in the same way as the stationary battery to adjust PV power and the electricity demand.
