Research on Layout of Energy Storage Stations Connected to Grid Based on Optimal Grid Impact

With the rapid development of distributed power generation with renewable energy as the core, the proportion of energy storage stations connected to the grid is constantly increasing. The access of a large number of energy storage stations will inevitably affect the voltage level and line flow level of the distribution network. Therefore, by reasonably optimizing the access location and capacity of the energy storage station to ensure that its impact on the distribution network is optimal. On this basis, this article uses a multiobjective optimization method to define the minimum voltage deviation, the optimal transmission line margin, and the minimum network loss as the optimization goals. And the firework algorithm is used to solve the problem, and the best access location and access capacity of the energy storage station are obtained. Finally, the IEEE35 node case is used in MATLAB to carry out the simulation calculation to prove the validity of the conclusion. Therefore, the planning scheme of energy storage station proposed in this article has effective theoretical significance and practical value.
