摘　　要：电动汽车的时空行为包括时空转移行为和时空充电行为。如何对电动汽车时空行为进行精确建模已成为大规模电动汽车与电网进行有效互动的关键。该文引入活动分析法将出行行为理解为活动的派生行为,建立用户一天中不同活动-出行链间的时空转移关系;基于累计前景理论描述了用户在活动-出行链中的出行方式、出行路径、出发时刻选择上的有限理性心理;在此基础上考虑交通网络的动态特性和电动汽车的充电特性,研究了电动汽车在每条活动-出行链上的时空分布特性和充电特性;并在典型网络(Nguyen-Dupius网络)中对不同用户心理、电动汽车占比、充电站服务能力约束下的电动汽车时空转移和充电特性进行算例分析。计算结果表明所提方法能够更加合理地刻画用户选择心理及描述电动汽车用户时空行为,且发现电动汽车占比和充电站服务能力均对其有较大影响。The spatiotemporal behavior of electric vehicles(EVs) includes spatiotemporal transfer behavior and charging behavior. The accurate modeling of the spatiotemporal behavior of EVs has become the key to the effective interaction between large-scale EVs and power grid. The idea of activity-based analysis to understand the travel behavior as the activity derived behavior was applied in the paper, and the transfer relationship between different activity chains was established. Based on the cumulative prospect theory, the bounded rationality psychology of users in the choice of travel mode, travel path and departure time was described. Considering the dynamic characteristics of traffic network and the charging characteristics of EVs, the spatiotemporal distribution characteristics of EVs on each activity chain were studied. Finally, the Dupius network, a typical traffic network, was used to study the spatiotemporal transfer and charging behavior characteristics of EVs with different users’ psychologies, proportions of EVs and service capabilities of charging stations. The simulation results show that the proposed method can more reasonably describe the user s’ choice psychology and the spatiotemporal behavior, and it is found that the proportion of EVs and the service capacity of charging station have great effect on them.
