摘要： 风力发电具有明显的随机性,间歇性,不可控性和反调峰特性,风力发电的大规模并网给电网调峰和稳定,安全运行带来了巨大压力,造成弃风限电现象愈加严重,严重影响了风力资源的有效利用和经济效益.全钒液流电池储能电站在能量管理系统的调度下,对风力发电输出功率进行平滑,配合风电场功率预报系统,提高风电场跟踪计划发电能力,改善了风电场并网电能质量,降低了对电网的冲击与影响,同时也提高了风电场输出功率可控性,有利于提高电网对风电的接纳能力.国电龙源卧牛石风电场配套的5 MW/10 MW∙h全钒液流电池储能系统为目前世界上最大规模的全钒液流电池储能系统.本文介绍了该全钒液流电池技术特点和储能系统的设计,成组方案及功能,并对储能技术在可再生能源发展中的作用进行了展望.

Abstract: Wind power generation is featured by variability, uncertainty, difficult to control and abundance at off-peak hours. These present challenges in large scale integration of wind power into electrical grids including peak-shaving, safety and grid stability, which contribute to serious wind power curtailment and reduction in economic benefits of many wind farms. Vanadium redox flow battery energy storage systems provide a solution to smooth the power output of wind farms and enhance the capability of tracking generation plan coordinate with the power forecasting system which are helpful to integration of wind power. This paper gives an introduction to the 5 MW/10 MW∙h all-vanadium redox flow battery energy storage power station, co-developed by Dalian Rongke Power Co. Ltd. and Dalian Institute of Chemical Physics of Chinese Academy of Sciences, for Woniushi wind farm of China Guodian Longyuan Power Group. This all-vanadium redox flow battery system is currently the world's largest one.

Key words: wind power, all-vanadium redox flow battery, energy storage technology
