Layered real-time scheduling strategy considering frequency response for electric vehicle stations
In this paper,a hierarchical strategy is proposed for real-time scheduling of a large number of electric vehicle loads in charging stations.Taking the three schemes,based on benefit of charging station,tracking refer-ence power,and integration of benefit and tracking respectively,as the upper optimization objective,the optimal load value of charging station is obtained by using particle swarm optimization algorithm.According to the results of upper optimization,a charging power allocation method based on urgency of users'charging demand consider-ing frequency response is proposed to formulate a charging scheme for electric vehicles.Finally,the effectiveness of the layered real-time scheduling strategy is verified by an example,which can meet both the charging demand of electric vehicles and the economic operation of charging stations and power grids.
