Bi-Level optimization model of energy storage systems under new energy generation integratio
A bi-level optimization model of energy storage system under wind and solar power access is proposed to solve the problems of increased network loss and reduced power quality caused by the access of renewable distributed power sources such as wind and photovoltaic power generation to the grid.Considering the coupling effect of energy storage planning and operation,the upper model takes the location and capacity of energy storage configuration as the decision variables,the planning cost of energy storage system as the objective function,the lower model considers the economy and stability of the power grid when the energy storage system is running,the output of the energy storage system at each moment(time scale is 1h)as the decision variables,and the vulnerability of the power grid,active network loss Power purchase cost is the objective function.The improved whale optimization algorithm and the YALMIP+CPLEX joint method are used to solve the problem in MATLAB.The improved IEEE33-bus system is selected for simulation verification.The results verity that the proposed model is reasonable.The optimal configuration scheme and operation strategy of energy storage are obtained by comparing different scenarios and results.
