小区规模化电动汽车充电策略

Charging Strategy for Large Scale Electric Vehicle in Residential Area

针对电动汽车规模化接入配电网与小区配电网约束用户充电需求的矛盾,首先将现有充电策略研究内容分为转移负荷和补给容量两大类,列出了基于居民出行习惯的充电特征数学模型,归纳了包括时间、价格、空间、电站/变压器、分布式电源、电动汽车和电网互动(V2G)电源6大影响电动汽车充电的关键因素。其次从不同角度分析各因素之间的关系,提出了符合工程典型应用的多目标协同优化充电研究方向。最后对影响电动汽车充电的其他目标因素研究进行了展望。

In view of the contradiction between the large-scale access of electric vehicles to the power distribution network and the residential power distribution network to restrict users’charging needs.Firstly,the research contents of existing charging strategies were divided into two categories:transfer load and supply capacity.The mathematical model of charging characteristics was listed based on residents’live habits.The key factors affecting electric vehicle charging were summarized,including time,price,space,and power station/transformer,distributed power,V2G power.Then,the relationship between various factors was analyzed from different angles,and the research direction of multi-objective collaborative optimized charging in accordance with typical engineering applications was proposed.Finally,the research on other target factors affecting the charging of electric vehicles was prospected.
