摘要
储能是促进可再生能源利用、保证电网安全稳定运行的有效手段。据统计,2019年全球已投运储能项目(含物理储能、电化学储能以及熔融盐储热)累计装机规模达183.1 GW,同比增长1.2%。储能技术按照能量转化机制可划分为物理储能、化学储能、其他储能等多种类型,各有不同的适合应用领域。随着新能源发电的迅猛发展,特高压电网的加快建设,储能市场将会迎来快速增长。本文主要介绍了目前储能技术的发展现状,以及在电力系统发、输、配、用等方面的应用情况,并对未来储能技术的发展趋势进行了展望,可为储能技术研究和工程实践提供参考。
Energy storage is an effective approach to achieve the absorption of renewable energy and ensure the safe and stable operation of the power grid.In 2019,the cumulative installed capacity of power storage projects(including physical energy storage,electrochemical energy storage,and molten salt heat storage)that have been put into operation worldwide reached 183.1 GW,a year-on-year increase of 1.2%.According to the energy conversion mechanism,energy storage technology can be divided into physical energy storage,chemical energy storage and other energy storage.Different energy storage technologies are applied in different fields.With the development of new energy technology,the energy storage market will usher in rapid growth.This article mainly introduces the current development of energy storage technology and its application in the four aspects of power system generation,distribution,transmission and use.Moreover,it prospects the development trend of energy storage technology in the future,which can provide a certain reference for technical research and engineering practice of energy storage.
