分布式光伏灵活并网集群调控技术综述

Overview of flexible grid-connected cluster control technology for distributed photovoltaic

分布式光伏发电单体可控性差且波动性强,其大规模汇集极大地影响了电网的安全稳定运行。文中从分布式光伏发电系统的集群划分和运行控制两个方面介绍了国内外对光伏发电研究的新趋势,重点评述了集群划分标准的异同和划分算法的优劣,并从三个方面论述了集群控制的概念和方法。

The distributed photovoltaic power generation unit has poor controllability and strong volatility,and its large-scale collection greatly affects the safe and stable operation of the power grid.This paper presents the novel trend of photovoltaic power generation research at home and abroad from two aspects of cluster division and operation control of distributed photovoltaic power generation systems,emphasizes the similarities and differences of cluster division standards and the advantages and disadvantages of the division algorithm,and discusses the control concepts and methods of clusters from three aspects.
