摘要提出了基于虚拟电价理论的电动汽车(EV)充放电优化调度思想,构建了以削峰填谷为目的、兼顾配电系统负荷信息与用户电能损失费用及电池损耗成本的EV充放电优化调度和实现机制模型。在所建的模型中,通过虚拟电价将充放电功率与系统负荷信息相关联,并研究了根据虚拟花费最小进行EV充放电优化的功率调节方法。在此基础上,综合小波分析和模糊聚类确立了用于EV充放电的动态分时电价机制,以保障调度策略的可实施性。最后,以某小区充电设施集群为例对5种优化模式进行了仿真分析,算例结果说明了所述模型的基本特征。

Abstract：The optimal scheduling of electric vehicles’ (EVs) charging and discharging based on virtual time-of-use (vTOU) tariffs is put forward.By taken the load information of the distribution system,the power loss cost,and the battery consumption cost of customers into consideration,the models of the charging and discharging optimal scheduling and the implementation mechanism are developed for the purpose of peak shaving.In the proposed models,the charging and discharging power is associated with the load information by vTOU tariffs.Then the power adjustment of the EVs is researched based on minimizing the virtual cost.Accordingly,a dynamic time-of-use tariff for EVs’ charging and discharging is established based on the wavelet analysis and the fuzzy cluster to ensure the implementation of the scheduling strategy.Finally,five optimization modes are simulated by charging piles in a residential district.The results illustrate the basic characteristics of the proposed models.

Key words： Electric vehicle (EV) virtual time-of-use tariff peak shaving charging and discharging optimization adjustable power implementation mechanism
