在研究中国电动汽车相关政策、发展趋势的基础上,基于调研结果,分析了不同类型电动汽车不同充电行为对应的充电方式及充电时段。根据不同类型电动汽车不同充电行为的充电功率,提出采用蒙特卡洛模拟抽取起始荷电状态、起始充电时间的电动汽车充电负荷计算方法。该方法将不同车辆的不同充电行为按充电需求进行分类,根据充电方式、起始荷电状态、充电需求、起始充电时间计算充电时间,获得充电负荷曲线。对中国未来电动汽车充电负荷水平进行了计算和分析。分析结果表明：随着中国电动汽车的发展,充电负荷将对电网的运行和规划带来较大的影响;充电负荷具有明显的峰谷差,负荷调控的潜力大。

The policy and the development of plug-in electric vehicles（PEVs） in China are analyzed first.Then the charging modes and charging time of different kinds of PEVs＇ charging behaviors in China are proposed according to the field survey.The charging periods of different kinds of PEVs＇ charging behaviors are divided.The Monte Carlo simulation method is applied to determine the starting state of charge（SOC） and the initial charging point.With the charging methods（either on slow,regular,or fast mode） and initial charging point,together with the sampled starting SOC and charging needs of different PEVs＇ charging behaviors,the charging time can be calculated to get the charging curve.Based on the study,the future charging load in China is forecasted.The results indicate that the charging of PEVs will have significant impacts on the planning and operation of the power system.The huge difference between charging peak and off-peak provides a substantial potential to coordinate the charging of PEVs.
