摘　　要：目前对电动汽车参与电力系统调频的研究,通常把电动汽车作为能量储存系统参与电网互动,并未考虑其作为交通工具的主要特性。事实上,只有处于可控状态的电动汽车,才能通过电动汽车与电网互动(vehicle-to-grid,V2G)技术向电网提供频率调整辅助服务,即电动汽车参与电力系统调频。因此,要研究电动汽车如何有效响应系统调频控制信号及其对系统频率的影响,首先应研究可控电动汽车数量的动态变化情况。为此,提出了基于蒙特卡洛的电力系统调频可控电动汽车数量动态变化模拟算法,该算法可在缺乏大量电动汽车实际运行数据的情况下,计算出各时段处于可控状态的各类型电动汽车数量及可控电动汽车总数,以有效研究电动汽车对系统频率影响。最后,通过仿真结果验证了该算法的有效性和可行性。EVs can participate into the frequency regulation of grid through vehicle-to-grid（ V2G） technique when EVs are in the controllable state. In order to figure out EVs reaction when its receive frequency regulation single and howit influence frequency regulation,the research should be down to figure out the changes of controllable EVs ＇ number. Nowthere is fewresearch about the changes of controllable EVs ＇ number in a period time when participate into grid frequency regulation. Based on that,a arithmetic which based on M onte Carlo simulation was proposed to figure out the changes of controllable EVs＇ number. The proposed arithmetic can figure of the changes of EVs＇ number in 24 time period a day. The proposed arithmetic gives a great help to those who do searching but cannot get the practical data of EVs.
