Optimal configuration of ES capacity under the access of EV in V2G mode

The configuration of energy storage (ES) under the access of electric vehicles (EV) in V2G mode can be a research hotspot with a good application perspective. However, the existing research has not obtained compromise among the interests of the grid, ES system and EV users. In view of this problem, a multi-objective optimization model is established for photovoltaic (PV) ES capacity allocation considering EV access, which can balance the benefits of the grid, ES system and EV users. What’s more, the starting time and duration of EV’s time-of-use (TOU) price is taken as optimization variables to guide EV users’ charging and discharging behavior. The simulation results show that the proposed method can not only reduce the difference between peak and valley, but also benefit the users of ES and EV.
