摘要
市场环境下,实现电动汽车(EV)的有序用电调度,将为电网提供多样化的功率调节手段,支撑“双碳”目标下新能源为主体新型电力系统的建设。其中涉及多方市场参与者的决策博弈,是能源的信息-物理-社会系统(CPSSE)的典型应用之一。EV聚合商作为连接EV用户与电网的中间环节,需要处理好与用户之间的合约博弈,以及做好电力市场中的决策策略。该文以EV集群提供运行备用为背景,首先,分析了多方市场参与者的交互关系,提出EV聚合商与用户之间的合约机制;然后,分析了EV集群同时参与电能量市场与备用市场的耦合效应,通过聚合商参与备用辅助服务市场的机制设计,实现了EV正常充电与参与备用服务的解耦;最后,以聚合商风险收益最大为目标,构建多场景下聚合商同时参与日前电能量市场与备用市场的联合调度优化模型,通过算例仿真揭示了模型的有效性,实现了日内备用调度不确定性时的日前最优风险预防控制。
Electric vehicle(EV)is a kind of distributed electrochemical energy storage resource.As the intermediate link between EV users and power grid,EV aggregator needs to manage the contract game with users and the decision-making strategy in the power market,and faces the coupling problem of trading products when EV participates in multiple markets.In order to solve the above problems,the contract mechanism between the aggregator and EV users is proposed,the reserve auxiliary service market mechanism compatible with the aggregator’s participation is designed,and a joint dispatching optimization model of the aggregator participate in the day-ahead electricity energy market and the reserve market at the same time under multiple scenarios is constructed.Firstly,the interaction relationship between various market participants in the process of providing reserve by EV is analyzed,and the contract mechanism between aggregator and EV users is put forward:aggregator gives discount coefficients of charging price corresponding to different pricing element parameter values,that is,the types of orderly charging/discharging contract packages that users can participate in,and users compare which contract package meets the expected discount coefficient,and submit the information of using EV demand(that is,set the corresponding parameter values of each pricing element).Then,two kinds of coupling effects(the first kind of coupling effect:the coupling of reserve electricity and reserve capacity;the second kind of coupling effect:the coupling of reserve electricity and spot electricity)of EV clusters participate in the electricity energy market and reserve market at the same time are put forward and analyzed,and the prevention control before the occurrence of reserve shortage events are carried out through risk optimization in multiple scenarios to eliminate the influence of the first kind of coupling effect;for the second kind of coupling effect,the actually dispatched reserve electricity will be included in the electricity energy ma
