摘要(Abstract)：

随着电动汽车大规模发展,电动汽车充电负荷将会对配电网的安全与经济运行产生不容忽视的影响。以居民区配电网为研究对象,基于现有居民区负荷的计算方法,考虑单个居民区住户数量分布,结合不同类型居民区用电特性,负荷增长特性,电动汽车驾驶以及充电行为差异,建立了居民区电动汽车数量分布及单个居民区内电动汽车充电功率需求的数学统计模型,提出了居民区接纳电动汽车充电能力的评估方法。算例评估结果表明,随着电动汽车渗透率的增加,居民区配电变压器接纳电动汽车充电能力存在明显差异。所提方法可有效评估各类居民区配电网接纳电动汽车充电的能力,评估结果具有实际指导意义。

关键词(KeyWords)： 配电网;电动汽车;充电负荷;接纳能力
