This article proposes an optimization method for energy storage configuration in isolated microgrids considering new energy output. Considering the output of new energy and the capacity of islanded microgrid energy storage systems, based on the output power of energy storage equipment, calculate the optimization parameters of energy storage configuration, establish the objective optimization function, calculate the fitness value of multi-objective optimization function, and thus obtain the optimal configuration scheme. The experimental results indicate that the proposed method is beneficial for improving the energy utilization efficiency of islanded microgrid systems and ensuring power supply stability.

Key words: new energy output, island microgrid, energy storage equipment, configuration optimization
