Distributed network construction type energy storage configuration method and system, terminal and storage medium

Abstract

The invention relates to the technical field of distributed power supplies, and particularly provides a distributed network construction type energy storage configuration method and system, a terminal and a storage medium, and the method comprises the steps: collecting the topological data of a whole network frame of a power distribution network, obtaining the source load characteristics of the whole network frame, and building a whole network frame structure model; calculating the voltage stability index of each node based on the topological data and source load characteristics of the whole grid of the whole grid structure model, obtaining the necessity degree of each node based on the voltage stability index of each node in combination with a preset evaluation threshold, and carrying out distributed grid construction type energy storage pre-site selection; constructing an outer-layer network construction type energy storage locating and sizing model, and constructing an inner-layer scheduling model; and respectively optimizing the locating and sizing result of the outer layer model and the power supply output of the inner layer model based on a swarm intelligence algorithm, and outputting a final distributed network construction type energy storage configuration result based on the locating and sizing result and the power supply output. And the problems of voltage stability and economy caused by the access of the distributed power supply and the multi-type load to the power distribution network are effectively solved.
