摘　　要：电动汽车充电负荷因受诸多因素影响而充满随机性与复杂性,随着电动汽车的规模化应用,势必会给配电网带来一系列问题,这也成为目前国内外学者和相关科研机构的研究热点。基于电动汽车充电运行数据,选取充电起始时间和充电持续时间作为影响充电负荷时间分布的关键因素,结合用户充电行为的不确定性分析,建立电动汽车充电负荷的时间分布模型。以此为根据,对充电负荷区域进行划分,建立电动汽车充电负荷的时空分布模型。通过算例分析,研究电动汽车充电负荷对配电网运行中的电压质量、网络损耗及日负荷曲线的影响。As the charging of electric vehicles is full of randomness and complexity,the large-scale application of electric vehicles is bound to bring a series of problems to the distribution network,which has become the research hotspot in the domestic and foreign scholars and research institutions. Based on a large number of the measured data on charging load of electric vehicles,choose the charging start time and duration of the charging as two key factors affecting the time distribution of charging load,combined with the analysis of the uncertainty of user charging behavior,build time distribution model of charging load of electric vehicles. According to this,divide the charging load area and the time and space distribution model of electric vehicle charging load was established. Through the example analysis,the impact of charging load of electric vehicle on the voltage drop,power loss and load curve of local distribution network was researched.
