多元复合储能系统及其应用

现代电力系统中，储能技术的作用日益凸显．然而，就目前储能技术的发展而言，没有一种储能装置可以同时满足电网多方面需求．主要研究多元复合储能系统及其在电力系统中的应用，通过合理组合和配置不同类型的储能装置，使其拥有优于单一储能方式的理想性能．并对比分析几种典型储能装置的性能参数、技术优势及发展现状．从应用场合、配置方式、拓扑结构以及经济性等方面人手，重点研究多元复合储能类型的配置及构建，提出多元复合储能系统的能量管理策略．

Composite energy storage systems and its applications

Electric energy storage （EES） system becomes more and more important in modern power systems. However, single type of EES device cannot satisfy the various demands simultaneously. In this paper, the CESS （composite EES） system and its application in power systems were studied. By combining and configuring various types of EES devices, the CESS system can achieve the required performances. Firstly, the performance parameters, technology advantages and current development conditions of several typical EES systems were introduced. Then, considering the application occasion, the EES devices configuration, the typology and the economy, the configuration and construction of CESS were studied. Finally, the energy management strategy, which acts as the key issues of the proposed CESS system, was analyzed.
