[Abstract]:This paper presents a charging and discharging control strategy for electric vehicle V2G based on synchronous inverter technology. Firstly, a T-S fuzzy controller is designed to determine the power flow relationship between electric vehicle and power grid, as well as the operation mode of synchronous inverter. Secondly, a charging and discharging control method of electric vehicle based on synchronous inverter is proposed, which realizes the bi-directional controllable regulation of active power and reactive power between electric vehicle and power grid. The electric vehicle has the function of providing frequency regulation and voltage regulation service to the power network. The proposed control strategy is simulated and tested under different initial battery states and different grid states. The results show that, The proposed control strategy can effectively realize the bi-directional regulation of power between the power grid and the electric vehicle according to the load of the power grid and the charging condition of the electric vehicle. Therefore, it is beneficial to maintain the stability of power grid and improve the efficiency of power grid while meeting the needs of electric vehicle users.
