摘　　要：电动汽车作为一种移动储能资源,可以通过运营商聚合参与电网紧急调控服务。针对电动汽车运营商参与紧急调控的功率分配策略问题,分析了电动汽车参与紧急调控的手段,并对不同类型的电动汽车用户参与紧急调控的灵活性和经济性开展分析。综合考虑负荷转移、充电量减少和反向充电3种调控方式,建立电动汽车参与紧急调控的功率分配优化模型,并对其进行松弛简化从而得到线性规划模型。算例分析表明,所提功率分配策略能够快速有效地实现车辆间的紧急调控功率分配,在传统有序充电调控外有效挖掘站内电动汽车的灵活性。As a mobile energy storage resource,electric vehicles can participate in the emergency control service of power grids through the aggregation of operators.The power distribution strategy of electric vehicle operators participating in emergency control is proposed,and the means of electric vehicles participating in emergency control is analyzed.The flexibility and economy of different types of electric vehicle users participating in emergency control are discussed.The power distribution optimization model of electric vehicles participating in emergency control is established by comprehensively considering the three control modes of load transfer,charge reduction,and vehicle-to-grid(V2G),and the model is further simplified to a linear programming model by relaxation.The case study shows that the proposed power distribution strategy can quickly and effectively realize the power distribution of electric vehicles for emergency control and effectively activate the flexibility of electric vehicles within stations beyond traditional orderly charging control.
