Comparison and Technology Outlook of Distribution Network Reconfiguration Methods

Under the goal of "carbon peaking and carbon neutral", the power distribution system is evolving into a platform for the optimal allocation of regional resources. It will play a key role in supporting the low-carbon transformation of energy supply and consumption in China. At the present stage, the research focuses on how to break through the tight coupling of network topology and system operation to achieve flexible network operation, to adapt to the flexible and controllable demand of large-scale distributed energy access. In this context, this paper first summarizes the distribution network reconfiguration methods from six aspects, including network topology, system load, distributed power sources, optimization objectives, constraints, and reconfiguration algorithms. Then, it analyzes and outlooks the key issues faced by it, such as the AC-DC distribution network reconfiguration algorithm, spatial and temporal decoupling of AC-DC distribution network under double high, and quantification of flexibility.
