摘要
电网侧储能有效增加了电网的调节手段和能力,有助于电网安全稳定运行。随着新能源高比例渗透和特高压电网的快速发展,系统波动等电网安全问题日益严重,电网需要构建高比例、泛在化、可广域协同的储能形态。因此,针对储能在电网侧应用的技术研究意义重大。介绍了电网侧储能技术国内外研究现状以及商业示范工程;梳理了项目选址以及优化配置方面的研究方法;通过理论以及时序指标分析电网侧储能需求;阐述了储能优化规划技术和经济性评估指标;指出了推广应用存在的难点。最后对电网侧储能技术的发展应用给出相应的建议和展望,为今后挖掘储能应用的效益价值,创新储能应用商业模式提供一定参考意义。
Grid-side energy storage is an effective means of operation regulation,which provides a flexible guarantee for the security and stability of the power grid. With the high penetration of newenergy and the rapid development of UHV power grids,grid security issues such as system fluctuations are becoming increasingly serious. In the power grid,a high proportion,widely existing,and wide-area collaborative energy storage model needs to be constructed. Therefore,it is of great significance to carry out technical research on energy storage on the grid side. This paper introduces current situation of research on grid-side energy storage technology and commercial demonstration project;summarizes methods for grid-side energy storage in site selection and optimization allocation;analyzes the demand of grid-side energy storage through theory and time-series indicators;expounds the optimization allocation technology and economic evaluation parameters in energy storage;and points out the difficult problems in promoting the application. Finally,the paper gives suggestions and prospects for development in grid-side energy storage technology,which has certain reference significance for exploiting the value in energy storage applications and innovating energy storage application business model.
