With the widespread application of renewable energy in the power system,the role of distributed energy systems(DES)in energy supply is becoming increasingly prominent.The randomness and intermittency of their power output have caused stability and reliability issues in the power system.Therefore,how energy storage technology can better serve the power grid has become an important issue.This article proposes a distributed energy system design and optimization scheme based on energy storage technology to address existing problems.A multi time scale collaborative optimization strategy is proposed by studying the working mode of energy storage systems and the application of energy storage technology in power grid frequency regulation.This strategy can achieve dual optimization of energy system economy and stability.On this basis,the relationship between the efficiency of energy storage systems and the power grid under different conditions was constructed and analyzed,and an optimized energy storage configuration scheme for power grid operation was obtained.The experimental results demonstrate that the proposed optimization strategy can effectively improve the operational efficiency of the power system,which is conducive to achieving economic operation and reliability of the power system.This provides theoretical support and practical application reference for the design and optimization of distributed energy systems based on energy storage technology.
