摘　　要：在“碳达峰、碳中和”背景下,大量分布式电源、电力电子设备接入到电网中,使网络结构面临复杂化,故需要寻求更优的配电网重构方案。为满足直流环节互联配电网可控需求,使网架拓扑结构与系统运行紧密耦合,进而实现组网灵活运行是现阶段研究重点。首先,对基于直流环节互联的交直流混合配电网展开分析;然后对考虑优化运行和故障恢复的几种常用的配电网目标函数及约束条件做了进一步讨论,并从经典算法、启发式算法、其他算法3方面探讨了其在直流环节互联配电网重构中的应用;总结了基于直流环节互联的配电网重构在优化运行和故障恢复面临的一系列挑战和技术需求;最后,展望了基于直流环节互联的配电网重构未来发展方向并给出了建议。With the context of“carbon peaking and carbon neutrality”,a large number of distributed power sources and power electronic devices are connected to the power grid,which complicates the network structure and requires the search for a better distribution network reconstruction scheme.In order to meet the controllable demand for DC link interconnection distribution network,so that the grid topology and system operation is closely coupled,and then realize the flexible operation of the group network is the focus of research at this stage.Firstly,the AC/DC hybrid distribution network based on the DC link interconnection is analyzed.Then,several commonly used distribution network objective functions and constraints considering optimized operation and failure recovery are further discussed,and their applications in the DC link interconnection distribution network reconstruction are explored from three aspects:classic algorithms,heuristic algorithms,and other algorithms.A series of challenges and technical requirements faced by the reconstruction of distribution network based on the DC link interconnection in optimized operation and failure recovery are summarized.Finally,the future direction of development for the reconstruction of distribution network based on DC link interconnection is envisioned and recommendations are given.
