Research on Optimal Configuration of Active Distribution Network Energy Storage Security Based on Improved Particle Swarm Optimization Algorithm

Exploring the optimal allocation method of energy storage in the overall operation of active distribution network, improving the performance of configuration model and Algorithmic efficiency. This paper first analyzes the safety characteristics of active distribution network including energy storage, and constructs the safety observation index and safety domain model. On this basis, improved multi-objective particle swarm optimization algorithm is used to study the optimal allocation method of energy storage safety of active distribution network, and simulation experiments are conducted to verify the optimization effect of the algorithm and allocation method. The results show that this article has made improvements to the initialization stage and speed update stage of the MOPSO algorithm, which can greatly improve the stability of the algorithm and increase computational time. The two-step energy storage optimization configuration method proposed in this article has significantly improved the overall security of the system, and prioritized the allocation of energy storage in areas with weak security in the system, making the system security more balanced.
