Energy storage configuration method and device for power grid region

The invention discloses an energy storage configuration method and device for a power grid region, and the method comprises the steps: obtaining a power grid structure and power grid data of a to-be-configured power grid region, and extracting power grid nodes and power grid lines from the power grid structure; according to the power grid data, calculating an electrical relation between power grid nodes as a modularity index; comprehensively considering the electrical connection among the power grid nodes in the to-be-configured power grid region and the transmission capability of the spare capacity to obtain a comprehensive performance index; dividing the to-be-configured power grid region into a plurality of shared regions by taking the optimal comprehensive performance index as a target; calculating an energy storage demand of the shared region in combination with an operation constraint condition of the to-be-configured power grid region; and configuring the stored energy of the to-be-configured power gri
