重载变电站中电化学储能站的应用

Application of Electrochemical Energy Storage Station in Heavy-duty Substation

储能是构建新型电力系统的重要灵活性资源,其中电化学储能是储能发展的“新星”。电化学储能站在电网侧的应用越来越广泛。在分析储能应用场景的基础上,结合电网侧电化学储能站布局的主要思路,提出针对单个重载市区变电站的储能布局分析思路,并在此基础上提出分区电网的储能配置分析,同时提出储能站的调度运行方式,对电化学储能站应用场景的选择具有指导意义。

Energy storage is an important flexible resource for building new power systems,among which electrochemical energy storage is a"new star"in the development of energy storage.The application of electrochemical energy storage stations on the power grid side is becoming increasingly widespread.On the basis of analyzing the application scenarios of energy storage,combined with the main ideas of electrochemical energy storage station layout on the power grid side,an analysis approach for the energy storage layout of a single heavy-duty urban substation was proposed.On this basis,an analysis of energy storage configuration for partitioned power grids was proposed,and the scheduling and operation mode of energy storage stations was proposed,which has guiding significance for the selection of electrochemical energy storage station application scenarios.
