摘要
随着我国风力发电和光伏发电的大规模建设,上网容量逐年增加,由于风能和太阳能的间歇性及波动性,为电网运行调度与保护控制带来了困难,弃风和弃光现象日益严重。为解决这一难题,大容量电池储能系统的研究十分必要,而能量变换系统PCS是电池储能系统的一个重要组成部分。为此本文介绍了基于三天平的大功率PCS功率拓扑结构分析研究。
With the large-scale construction of wind power and photovoltaic power generation in China,the network capacity is increasing year by year.Due to the intermittence and volatility of wind and solar energy,it is difficult for the operation and protection control of the power grid,and the phenomenon of abandonment and light abandonment is becoming more and more serious.In order to solve this problem,the research of large capacity battery energy storage system is very necessary,and the energy conversion system PCS is an important part of the battery energy storage system.Therefore,the power topology analysis of high-power PCS based on three balance is introduced in this paper.
