Research on integrated bidirectional control of EV charging station for V2G

With the increasing number of electric vehicles, the interaction between the electric vehicle and the power grid is becoming more and more obvious, V2G (Vehicle to Grid) technology has become a hot research. EV charging station is an electric vehicle energy supply station, how to efficiently realize the bidirectional interaction, reduce the EV charging damage and power pollution between vehicle and grid in EV charging station is a focus of attention. At present, charging or discharging usually requires separate equipment, in this paper, we realizes a high quality integrated operation of single charger for charging and discharging combined with space vector control and instantaneous reactive power theory, realized a effectively bidirectional interaction of V2G.
