Abstract In order to solve the problem of power fluctuations caused by the increasing output of volatile new energy sources in the current distribution network, an optimal energy storage configuration method that considers the time and space characteristics of AC/DC hybrid distribution network system power fluctuations is proposed to stabilize the energy storage system. First, a mathematical model for power generation and consumption is established, as well as constraints such as power flow, wind turbines and optical machines, and the alternating iteration method is used to calculate the power flow of the AC/DC hybrid distribution network. Then the model is solved by the fast non-dominated sorting genetic algorithm, and the final output is the comparison chart of the optimization index of the optimal solution and other feasible solutions. Through the optimized configuration of the energy storage system, the deviation value of the distribution network and the network loss are significantly reduced, which verifies the feasibility of the method proposed in the article.

Key words： AC/DC distribution network multi-objective optimization energy storage system configuration fluctuation suppression voltage deviation value sum network loss
