摘要
为了获得合理的分时电价来引导电动汽车进行有序充电,提出了一个基于负荷需求响应的电动汽车充电控制双层优化模型,在上层模型中系统调度旨在通过利用分时电价引导电动车用户将其充电负荷从负荷峰时段转移到谷时段以平滑系统总负荷;在下层模型中电动汽车代理商目标是在考虑电动汽车个体使用需求和停车区间等约束情况下制定出与上层充电命令偏差最小的实际充电计划;进一步提出了一种基于AMPL/IPOPT求解器的迭代求解算法;最后,采用改进的30节点系统来验证所提出方法的有效性。
To design a reasonable time-of-use(TOU)pricing mechanism to guide electric vehicles(EVs)charging for the purpose of load leveling and economic dispatch,a bi-level EV charging optimization model based on load demand response was presented.On the upper-level model,the system operator aimed to smooth the total load by applying TOU price to guide EV owners to shift their charging load from the peak period to the valley period.On the lower level,the EV aggregator aimed to minimize the deviation between the scheduled charging load commanded from the upper level and the real charging load on the lower level considering EV individual driving and parking constraints.AMPL/IPOPT was employed to solve the developed optimization bi-level model.Finally,the effectiveness of the proposed method was verified using a modified30-bus testing system.
