摘　　要：围绕国家“双碳”战略目标,配电网将加速向灵活互联、柔性可控的能源互联网资源配置平台转型升级,而在这一过程中需要重点解决配电网合环热倒的问题。探讨了配电网无法合环热倒的场景及原因,对目前已有的配电网合环热倒方式进行了研究,对不同合环热倒方式的经济效益及其对配电网的影响进行了对比分析,剖析了合环时短路故障对配电网的影响。在此基础上,总结出目前最适合我国配电网的合环热倒方式。Focusing on the national dual carbon strategy goal,the distribution network will accelerate its transformation and upgrading to a flexible,interconnected,and controllable energy internet resource allocation platform.It is necessary to focus on solving the problem of grid integration and hot swapping.This article explores the reasons why the distribution network cannot be closed for hot swapping,studies the existing methods of closed loop hot swapping,compares and analyzes the economic benefits of different closed loop hot swapping methods and their impact on the distribution network,and analyzes the impact of short circuit faults on the distribution network during closed loop.On this basis,the most suitable closed-loop hot swapping method for China’s distribution network is summarized.
