基于分时电价机制的电动汽车用户侧有序充放电控制策略

Coordinated Charge and Discharge Control Strategy Based on Time-of-use Price from Electric Vehicle Customer Side

电动汽车正大规模发展,未来可能有电动汽车用户为方便快捷采取家庭充电方式。针对这一方式,提出一种有序充放电控制策略。根据上级系统提供的充放电功率限制和充放电电价,引入激励因子,通过优化各时段充放电功率,建立以用户总支出费用最低为目标的有序充放电模型。在仅充电和充放电案例分析中,应用单纯形方法,求得最优解,为电动汽车用户提供经济的有序充放电方案。

With the large-scale development of electric vehicles, EV users prefer to take a quick and easy way of personal charging in the future. Based on this trend, a coordinated charging and discharging control strategy is proposed in this paper. According to the constraints of charge-discharge power and the electricity price of charging and discharging provided by the superior system, a coordinated charging and discharging model is proposed to minimize the fee of the total expenditure for EV users by introducing incentive factor and optimizing the charging and discharging power each time. In case studies, the economical charge-discharge solution is provided for EV users by applying the simplex method to obtain the optimal solution.
