Research on the Application of New Hybrid Energy Storage Technology in Micro Grid

储能系统作为微电网中必不可缺的能量管理单元,已成为国内外电力领域研究的热点。为了满足电力负荷的需求和提高供电的可靠性,储能技术对微电网的供电可靠性、经济运行和安全具有重大影响性。文中从储能技术应用模式和分类的角度,简述了在微电网中应用混合储能技术的必要性,着重介绍了应用在微电网中的几种新型混合储能方式,如压缩空气和钒液流电池混合储能,超导和蓄电池混合储能,超级电容器和锂电池混合。

The energy storage system viewed as essential in the micro grid power management unit, has become a hots- pot in research of domestic and foreign power. In order to meet the requirements of power load and improve the reliability of power supply, energy storage technology for micro power grid has a great influence on power supply reliability, economic operation and safety. This paper expounds, in micro power grid, the necessity of the application of hybrid energy storage from the perspective of energy storage technology application model and classification. Several new hybrid energy storage methods for the application of micro grid are emphatically introduced, such as compressed air and vanadium flow battery hvbrid energv storage, superconducting and hybrid energy storage battery, super capacitor and lithium batteries.
