Community Energy Management with Electric Vehicles for Effective Use of Solar Energy

Photovoltaic generation (PV) output varies depending on the time, weather, and season. In these days, batteries equipped in electric vehicles (EVs) can be utilized as substitutes for the storage systems, and are expected to use output of PV generation efficiently. In this paper, authors propose an energy management method with EV batteries to improve the rate of utilization of PV output in the community consisting of houses with PV and EVs. As the result, it demonstrates that power interchange between houses with the appropriate charge-discharge management of EV batteries can improve the effective use of PV.
