Optimal electric vehicle scheduling in smart home with V2H/V2G regulation

The popularity of electric vehicle (EV) provides both challenges and opportunities. Although EV increases the load pressure to the grid, it can also serve as the potential storage to facilitate the demand response for residential customers. In this paper, we propose an optimal and automatic scheduling scheme to exploit the benefits of EV not only from residential side but also from utility companies. Specifically we consider that the EVs can achieve a two-way discharging, either supply the power usage of its house (i.e., V2H) when the electric price is high or sell back to the Grid (i.e., V2G) if the market price is more attractive. The objective is to minimize the total cost, including electricity expenditure and storage depreciation cost, while satisfying various practical constraints. Simulation results show our proposed scheme can not only lower the cost but also share part of the pressure from utility companies.
