摘要

推动分布式光伏集群并网是实现中国双碳目标的有效举措之一。然而，强随机性、间歇性的分布式光伏集群分散无序的接入，给电网带来了系统惯量不足、系统强度减弱等系列问题。为此，文中对分布式光伏集群优化控制技术进行系统梳理和总结归纳。首先，归纳并阐述分布式光伏集群优化控制技术的研究方式及现状；其次，分析不同并网方式之间的差异及大力推广集群并网的原因，及集群划分算法和判据；紧接着，介绍储能和控制等集群优化控制关键技术。最后，考虑实际工程需求，对分布式光伏集群面临的挑战和未来发展趋势做了进一步阐述，并基于国内外分布式光伏集群优化控制的先进经验，提出了分布式光伏集群优化运行发展的建议。

Abstract

Promoting the grid connection of distributed photovoltaic clusters is one of the effective measures to achieve dual carbon target in China. However

the scattered and disordered access of highly random and intermittent distributed photovoltaic clusters has brought a series of problems to the power grid such as insufficient system inertia and weakened system strength. To this end

in this paper the distributed photovoltaic cluster optimization control technology is systematically sorted out and summarized. Firstly

the research mode and current status of the distributed photovoltaic cluster optimization control technology are summarized and elaborated. Then

the differences between different grid connection methods

the reasons for vigorously promoting cluster grid connection as well as cluster division algorithms and criteria are analyzed. After that

the key technologies for cluster optimization control such as energy storage and control are introduced. Finally

considering the actual engineering needs

the challenges and future development trends of the distributed photovoltaic clusters are further elaborated and

based on the advanced experience of optimal control of distributed photovoltaic clusters both at home and abroad

suggestions for the optimal operation and development of distributed photovoltaic clusters are proposed.
