虚拟电厂(virtual power plant,VPP)可聚合多利益主体的分布式资源(distributed energy resources,DER)参与电力市场,以深入挖掘分布式能源的调度潜力,如何考虑各运行主体的协同调度,提高整体收益成为当前亟需解决的重要问题。基于此,...虚拟电厂(virtual power plant,VPP)可聚合多利益主体的分布式资源(distributed energy resources,DER)参与电力市场,以深入挖掘分布式能源的调度潜力,如何考虑各运行主体的协同调度,提高整体收益成为当前亟需解决的重要问题。基于此,提出了计及风光及市场电价不确定风险和多主体协同的虚拟电厂参与主辅市场联合优化策略。首先,建立电动汽车群体(electric vehicle duster,EVC)的可调度域评估模型,在此基础上考虑VPP与EVC两主体的利益均衡,提出VPP与EVC主从博弈的主能量市场日前竞标模型;其次,考虑电池储能系统(battery energy storage system,BESS)快速充放电的特性,进一步提出VPP参与主能量市场和辅助调频市场的日前联合投标模型和VPP实时调整及调频响应模型;最后,在日前联合投标模型中引入条件风险价值(condition value at risk,CVaR),衡量日前投标收益与不确定风险的关系。基于某省电力市场规则进行算例仿真表明,所提VPP优化策略能通过提供调频服务和鼓励EV响应调度提高VPP的综合收益。展开更多
