中文摘要：

在主动配电网中,电动汽车是一种十分灵活的需求响应资源。对集群电动汽车充、放电过程进行合理有序控制,可以实现电动汽车和主动配电网的协调互动,提高主动配电网运行效率。该文在不违反电动汽车用户充电需求约束的前提下,提出了考虑放电模式的单台电动汽车迟滞控制模型。在此基础之上,提出了一种基于迟滞控制模型的集群电动汽车参与实时需求响应的V2G控制策略,该策略利用提出的电动汽车状态优先综合指标,有序控制电动汽车的充、放电过程,实现了集群电动汽车充、放电功率大小的实时调节。最后,仿真算例表明,利用文中提出的控制策略,集群电动汽车能够精确、快速地跟踪响应配电系统控制中心给出的功率跟踪目标,验证了文中提出方法的有效性。

英文摘要：

Electric vehicles（EVs） are flexible demand response resources in active distribution networks（ADN）. With proper control of charging and discharging of aggregated electric vehicles, a friendly interaction between ADN and EVs can be achieved and ADN operating efficiency can be improved. Under premise of meeting customers＇ charging needs, this paper proposed a hysteresis-based control model of one electric vehicle with discharging mode taken into consideration. Based on the model, a vehicle-to-grid（V2G） control strategy is developed for aggregated electric vehicles to participate in real-time demand response. The proposed strategy regulates charging power of aggregated electric vehicles by selectively changing charging states of electric vehicles based on state priority index. Finally, this control strategy is evaluated with several simulations and the results indicate that EVs are capable of accurately and quickly tracking target power received from system operator with the proposed method, validating effectiveness of the method.
