摘要：
In response to the possibility of extreme disasters causing communication and physical network failures in the smart distribution network information system (smart distribution network CPS), existing fault recovery strategies are inefficient in dealing with such problems and cannot obtain optimal solutions. The article proposes a post-disaster fault recovery strategy for active distribution networks, considering the coupling relationship between communication and physical networks. Firstly, the coupling relationship between communication networks and physical networks is modeled using graph theory. Based on this, a coordinated recovery model for active distribution network communication networks and physical networks is established by considering island partitioning, network reconstruction, and dynamic coordination of communication and physical system maintenance strategies. Solving this fault recovery strategy yields the optimal post-disaster coordinated recovery plan for active distribution networks that considers the coupling relationship between communication and physical. Finally, taking the communication network and the improved IEEE33 node system as examples, the results of various optimization schemes proposed in this paper are analyzed to verify the superiority of the proposed strategy. © 2024 Power System Technology Press.
