摘要
根据局域配电网的特点,建立了满足电网和电动汽车用户需求的充电控制系统模型。该系统包括充电分时电价时段划分模块、有序充电模块和用户响应评价模块。充电分时电价时段划分模块利用模糊聚类和曲线特点辨识的方法,并结合用户响应评价模块的分析结果,对充电分时电价进行了时段划分。根据时段划分的结果,有序充电模块以用户充电费用最低和尽早充电以及电网负荷曲线方差最小为目标对电动汽车进行有序充电管理。对充电控制系统进行了建模仿真,仿真结果表明:与即来即充的无序充电结果相比,该系统不仅以最低的充电费用完成用户的充电需求,而且利用电网昼夜负荷较低处充电,合理分散了用电高峰期电动汽车的充电功率。
A charging control system model is developed based on the characteristics of local distribution network to meet the demands of both power grid and EV（Electric Vehicle） user,which includes three modules：YOU（Time-Of-Use） charging period division module,coordinated charging module and user response evaluation module. Combined with the results of user response evaluation module,the period division module applies the methods of fuzzy cluster and curve feature identification to divide the periods of TOU charging price,based on which,the coordinated charging module manages EV charging with three control objectives： minimum customer charging fee,minimum load curve variance and earliest charging service. Simulative results indicate that,compared with the uncoordinated charging management,users＇ charging demand is met with the minimum charging fee and the EV charging load is reasonably shifted from daily load peak period to valley period.
