锂电池储能系统在重要用户配电网的应用设计

Application Design of Lithium Battery Energy Storage System in Important User Distribution Network

摘要: 近年来，新型储能技术的应用领域不断拓展，并且已成为组成电力系统不可或缺的一分子。本文简明阐述了锂电池储能技术的发展以及锂电池电池储能系统应用于配电网的概况，且以某400 kW的典型用户为例，设计一个整套400 kW∙h磷酸铁锂电池储能系统，并基于PSCAD对该系统进行电磁暂态的仿真，仿真结果表明，该储能系统能够很好的应对此典型重要用户的电磁暂态过程，进而更好的保障该用户的用电可靠性与安全性。

Abstract: In recent years, the application fields of new energy storage technologies have been expanding and become an indispensable part of the power system. This paper briefly describes the development of lithium battery energy storage technology and the application of lithium battery battery energy storage system to the distribution network. With a typical user of 400 kW as an example, we design a complete set of 400 kW•h lithium iron phosphate battery energy storage. The system and the electromagnetic transient simulation of the system based on PSCAD; the simulation results show that the energy storage system can well respond to the electromagnetic transient process of this typical important user, and thus better protect the user’s power reliability and security.
