摘　　要：提出一种基于T-S模糊控制器、用于实现电动汽车接入电网(V2G)技术的电动汽车智能充电站控制策略,阐述了该智能充电站的结构和原理,研究电网在不同负荷状况以及电动汽车在不同荷电状态下,进入智能充电站的每一辆电动汽车和电网之间的功率流向关系。仿真结果表明,所提出的控制策略可以有效地根据电网负荷情况和每辆电动汽车的荷电状态实现功率的双向智能分配,从而保障电网的稳定性、提高电网效率。This paper presents a control strategy for electric vehicle smart charging station in vehicle-to-grid （V2G） scenario. Firstly, the architecture and principle of the smart charging station are introduced. Then, a Takagi-Sugeno fuzzy logic controller is designed to control the power flow between EVs and grid depending on the battery state of each EV and the present grid condition. After that, a power distribution method is presented to distribute power to each individual EV according to its battery state and preset charging time. Simulation results demonstrate that the proposed control strategy can effectively allocate charging/discharging of the electric vehicle based on the grid condition and each EV＇s battery state.
