The paper analyzes the factors that affect the energy storage configuration caused by the integration of renewable energy generation, analyzes the charging and discharging scheduling strategies of the energy storage system, and establishes corresponding mathematical models. The paper proposes an improved particle swarm optimization algorithm. Simulation and case analysis show that the algorithm can stably achieve optimized configuration, stable frequency regulation, and reduce carbon emissions of the energy storage system.
