摘要
分析了电动汽车的充电电池结构,给出了单台电动汽车充电功率的计算公式.研究了对电动汽车充电负荷起决定作用的电池剩余荷电量和电动汽车返回时间两个随机因素的分布特性,并用蒙特卡洛法模拟这两个随机因素,提出了居民区电动汽车充电负荷的建模方法.方法能够较好地切合居民区电动汽车充电负荷的实际情况,对制定引导电动汽车用户有序充电的措施和配电网优化运行意义重大.
The structure of the rechargeable battery of electric vehicles was analyzed and the formula for calculating the charging power of a single electric vehicle was proposed.The distribution of the two key factors for charging load,as the residual charge of the battery and the return time of the electric vehicle,was studied.These two random factors were simulated with the Monte Carlo method.Then the modeling of electric vehicle charging load in residential areas was examined.The modeling could meet the actual situation of electric vehicle charging load in residential areas better,and it was of great significance to guide the charging of electric vehicle users and optimize the operation of distribution network.
