Economic Evaluation Method for Cooperative Optimal Dispatching of Clustering Energy Storage and Wind-Driven and Coal-Fired Generator

Economic evaluation method for cooperative optimal dispatching of clustering energy storage(CESs) and CFGs generators(WDGs) and CFGs(CFGs) is presented in this paper. In order to effectively quantify the role and value of the CESs, an evaluation method for the business model of a power system with collaboration and interaction of WDGs, CFGs and energy storage(ES) is proposed. Considering the factors such as the life cycle cost of the CESs, the coal consumption of CFGs, and the wind abandonment of WDGs, the objective function is established to minimize the operative cost of the CESs for participating in peak shaving and valley filling of power system. From the perspective of power grid, WDGs, CFGs and CES, the corresponding constraints are established respectively, and the operation curve of CESs is solved through CPLEX solver.
