The effective energy storage capacity allocation methods are studied for microgrid with wind /PV power generation in order to improve the optimal configuration of the distributed power supply,and meet the minimum operating cost requirements. The planning method for schedulable storage capacity of wind /PV power generation is researched and the energy management model for microgrid energy storage unit and power generation unit is established. In combination with the relationship among energy storage power,generation output and microgrid power,the objective function and constraint function are built for microgrid storage capacity allocation planning. The investment cost for the energy storage service life and the power generation cost are taken as objective functions,and the method of neural network based on genetic algorithm are used for solving. Example shows that the energy storage capacity allocation planning method effectively implements the microgrid energy configuration and power energy management control,and improves the utilization of resources.
