An optimal energy storage configuration method for a micro-grid considering source-charge-storage co-operation

The invention discloses an optimal energy storage configuration method for a micro-grid considering source-charge-storage co-operation. Firstly, the reliable output and load characteristics of distributed generation are obtained by simulating the output characteristics of distributed generation and investigating the load characteristics of micro-grid. Secondly, the power characteristic curve of the micro-grid is generated. By superposing the trusted output and load characteristics of distributed generation, the power characteristic curve of micro-grid is obtained. Thirdly, the upper optimization model and the lower optimization model of energy storage optimal allocation in micro-grid are established. Finally, the upper optimization model and the lower optimization model are solved iteratively, and the optimal energy storage allocation scheme of microgrid is obtained. The invention aims at minimizing the comprehensive cost of the energy storage year, and establishes an upper layer optimization model. In order
