中文摘要:

      为进一步提高电动汽车有序充电用户参与度，降低峰期电动汽车充电负荷，延缓配电变压器过载，结合住宅小区电动汽车停留时段，综合考虑用户充电意愿及峰谷分时电价时段划分，设置中长期有序充电和长期有序充电两种管理模式，满足不同充电需求的用户参与有序充电。其中，中长期管理模式根据住宅小区居民负荷曲线变化特征，采用倒序法选取充电开始时刻，达到削峰、移峰的效果；长期管理模式采用最小值最大法选取充电开始时刻，达到填谷的效果。仿真结果表明，通过协调控制不同管理模式的用户参与度，可进一步降低负荷峰谷差，减小负荷方差，降低充电费用，所提策略为用户提供更多样的选择。

英文摘要:

      In order to improve the participation ratio of electric vehicle users in orderly charging, reduce the charging load ofelectric vehicles in the peak period, and delay the overload of distribution transformers, the medium charging management mode and longterm charging management mode are setted. According to the user’s willingness to charge, time of use electricity price period,and the residence time of electric vehicles in residential areas,which can meet different charging needs in orderly charging.Among them, the charging start time of the medium charging man agement mode is selected by the reverse order method to achieve the peak cutting and peak shifting effect, according to the residen tial load change characteristics, and the long term charging manage ment mode uses the maximum minimum load value method to select the charging start time to achieve the effect of filling the valley.The proposed strategy provides users with more choices and the simulation results show that the load peak and off peak difference,the load variance, and the charging cost can be further reduced,through coordinating the user participation ratio of different man agement modes.
