摘要：

Aiming at the chain failures of active distribution network caused by natural disasters，an island partition method of active distribution network after disaster considering the importance of information-energy coupling nodes is proposed to realize the continuous power supply to important nodes. Based on the coupling relationship between power network and power communication network，the network architecture of distributed cyber-physical system is constructed with power network as the basic network. Combining the business characteristics of energy flow and information flow，the importance of coupling nodes is obtained by the weighting method combining subjective and objective. Based on the global information discovery model，the global information is obtained through local information exchange to complete the acquisition of the input parameters for the island partition model and meet the communication requirements after disaster. By controlling the switching state of automatic switchgear，distributed generation（DG） and energy storage，the active distribution network is divided into several microgrids powered by DG or DG in cooperation with energy storage to maximize the equivalent recovery load. The effectiveness of the proposed method is verified by the example simulation. © 2023 Electric Power Automation Equipment Press. All rights reserved.
