摘　　要：高比例分布式电源接入后的故障配电网,具备主动恢复与自治能力,有利于提升电力系统适应气候变化和灾害风险管理的水平,顺应配电网技术的发展方向。当前,配电网主动孤岛自恢复和稳定运行的研究受到广泛关注。首先,概述多源配电网主动孤岛的内涵,以及多源配电网孤岛与微电网孤岛的区别,分析归纳配电网主动孤岛在分布式电源高比例接入下稳定运行存在的关键问题。其次,从主动孤岛划分、孤岛自组网波动平抑控制以及组网完成后主动孤岛小干扰稳定控制3个方面阐述国内外研究现状,并进行总结。最后,基于电力物联网、高电力电子化下的小干扰抑制以及能源互联网背景下的主动孤岛方案,对多源配电网主动孤岛的发展前景进行展望和总结。The fault distribution network with a high proportion of distributed power supply access possesses active recovery and self-governance capabilities,which is conducive to enhancing the power system's adaptability to climate change and disaster risk management,aligning with the development direction of distribution network technology.Currently,research on active islanding self-recovery and stable operation of distribution networks has received widespread attention.This paper begins with an overview of the connotations of active islanding in multi-source distribution networks,as well as the distinctions between multi-source distribution network islands and microgrid islands.It then analyzes and summarizes the key issues that arise in the stable operation of active islands in distribution networks with a high proportion of distributed power supply integration.Subsequently,the paper elaborates on the current research status from three aspects:active islanding partitioning,fluctuation mitigation control for island selfnetworking,and small signal stability control for active islands after networking completion,followed by a summary.Finally,based on the internet of things for power,small signal suppression in the context of high power electronics,and active islanding solutions within the framework of the energy internet,the paper provides an outlook and summary on the development prospects of active islanding in multi-source distribution networks.
