摘要
针对电动汽车聚合商参与电网调频的调度与用户结算问题,提出了结合日前电量/备用优化、实时功率分配、聚合商与用户收益分成3个部分的运行框架。通过提出基于充电需求的裕度评估并将其作为核心参数,在日前阶段降低了充电/调频双重变量的复杂性,能够在日前联合优化充电电量和备用容量;并在实时功率调度,和各用户的调频贡献结算这2个过程中解耦充电功率和调频功率,实现快速求解、公平分配,并确保用户的充电需求得以满足。仿真验证了所提框架,并为了鼓励电动汽车用户参与,设计了2种不同参与程度的合约机制,展示并比较了用户视角下2种合约的充电情况和收益情况,证明了所提框架能够满足充电和调频的需求,并给用户带来收益。
To solve the problem of the dispatching and the users’settlement for the participation of EV aggregators in frequency regulation services,this paper proposes a three-part operation framework that combines the day-ahead energy/reserve optimization,the real-time dispatching,and the revenue sharing between aggregators and EV owners.By defining the operating margin restricted by the charging demand,the complexity of the dual charging/regulation variables is reduced,and the charging energy and reserve capacity can be jointly optimized day-ahead.In the processes of the real-time power dispatching and the frequency regulation settlement for each user,the charging power and regulation power can be decoupled to achieve a quick solution and a fair distribution,and the user’s charging demand can be ensured.Simulation results validates the proposed framework,and to encourage the participation of the EV owners,two contract mechanisms with different levels of participation are designed to demonstrate and compare the charging and revenue under the two contracts from the user’s point of view.
