摘　　要：电动汽车规模化应用后,其充电功率需求将会对原有的电网负荷产生很大的影响.对不同类型的电动汽车不同的充电功率,采用蒙特卡洛法抽取起始充电时间和日行驶里程来计算电动汽车的充电负荷,给出了多台汽车的充电负荷曲线.以某市夏季日负荷曲线为例,计算出不同规模电动汽车对原负荷曲线的影响.结果表明,电动汽车的自由充电特性使电网的峰荷产生了一定的增长.After large-scale application of electric vehicles, the charging power requirements of them will have a huge impact on the original grid load. The charging powers of different types of electric vehicles are analyzed in this paper. The charging loads of electric vehicles are calculated by extracting the start charging time and the day mileage using the Monte Carlo method, then the charging load curves of many electric vehicles are given. Taking the daily load curve of a city during a certain summer day for an example, the impacts of power demand of electric vehicles on different scales on original load curve are calculated. The results show that the free charging characteristics of electric vehicles give rise to an increase in the peak load of the grid to some extent.
