摘要采用二项分布描述电动汽车用户充电习惯的不确定性,本文建立了含有不确定性因素的充电负荷需求计算模型。基于此计算模型,分析了不确定性充电习惯、充电起始时间延时和充电功率对电动汽车充电负荷需求的影响;然后以配电网负荷方差最小为目标函数,以充电起始时间和充电功率为控制变量,考虑电动汽车充电功率约束和电动汽车用户充电能量需求约束,建立了基于不确定充电习惯的充电负荷优化调节模型。以北京市汽车行驶数据和典型配电网负荷数据为例,验证了本文所提充电负荷优化调节方法的优越性。

Abstract：A calculating model of electric vehicles’(EVs’) charging load demand concerning uncertainty factors is established in this work, in which, users’ charging habits is represented by binomial distribution. Based on this model effects of uncertainty factors including charging habits, charging start time delay and charging power to EVs’ charging load demand and distribution power load are investigated; and then an optimization model to adjust EVs’ charging load for uncertainty charging habit is proposed taking EVs’ charging start time and charging power as control variables, and the object function is to minimize the load variance with charging power limits and users’ charging energy demand as constraints. Taking EVs’ operating data and distribution power load data of a certain city as test case, advantages of the charging load regulation method is verified.
