【摘要】：提出一种基于同步逆变器技术的电动汽车V2G充放电控制策略。首先,设计了一个T-S型模糊控制器,用来决定电动汽车与电网之间的功率流向关系,以及同步逆变器的工作模式。其次,提出了一种基于同步逆变器的电动汽车充放电控制方法,实现了有功功率、无功功率在电动汽车与电网间的双向可控调节,使电动汽车具备了向电网提供频率调节和电压调节服务的功能。在不同初始电池状态以及不同电网状态下对所提出的控制策略进行了仿真测试,结果表明,提出的控制策略能够有效地根据电网负荷情况和电动汽车的荷电情况实现功率在电网和电动汽车之间的双向调节,从而在满足电动汽车用户用车需求的同时有利于维护电网的稳定,提高电网效率。
[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.
