摘要：
Taking typhoon disaster as an example, the automatic switch optimization configuration model considering the disaster resilience of distribution network is studied. Firstly, typhoon wind field, the fault state of distribution system and the uncertainty of system load are considered to generate random scenes. Secon-dly, the fault treatment of the distribution network during typhoon disaster and the power supply situation in the load area during power restoration are analyzed. Therefore, the automatic switch optimization configuration problem is modeled as a two-stage mixed integer linear programming framework. In the first stage, an automatic switch configuration scheme is obtained, which aims at minimizing the total cost of investment, ope-ration, maintenance and resilience. In the second stage, the power supply state of the load area is solved, which aims at minimizing the system resilience index during typhoon. Finally, the analysis of the example of IEEE 33-bus system shows that the automatic switch configuration scheme based on the proposed model has better economic efficiency and resilience improvement efficiency. © 2019, Electric Power Automation Equipment Press.
