摘要
随着可再生能源在电力系统中的广泛应用,分布式能源系统在能源供应中的作用日益凸显,其功率输出的随机性和间歇性引发了电力系统的稳定性和可靠性问题。因此,储能技术如何更好地服务电网成为重要议题。文章针对现存问题,提出基于储能技术的分布式能源系统优化方案。通过研究储能系统的工作模式和储能技术在电网频率调节中的应用,提出了一种多时间尺度的协同优化策略,这种策略可以实现能源系统的经济性和稳定性的双重优化。在此基础上,通过构建和分析不同情况下储能系统的工作效率与电网的关系,得到了优化电网运行的储能配置方案。试验结果证明,所提出的优化策略可以有效改善电力系统的运行效果,有利于提高电力系统的经济性和可靠性。这为基于储能技术的分布式能源系统的设计和优化提供了理论支持和实际应用借鉴。
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.
