SOP-based double-loop network wiring power distribution network fault recovery method and device

The invention relates to a power distribution network fault recovery method and device for double-loop network wiring based on SOP, and the method comprises the steps: determining a typical fault scene of a power distribution network, and obtaining the fault line condition of the typical fault scene; a robust fault recovery model of the power distribution network is established, the model aims at minimizing the sum of load power loss, network loss cost and distributed power supply operation cost, and constraint conditions comprise multi-port intelligent soft switch operation constraints; camp is adopted; the CG algorithm decomposes the established robust fault recovery model of the power distribution network into a main problem and a sub-problem, then the main problem and the sub-problem are solved, and according to a solving result, the power flow regulation and control capability of the intelligent soft switch and the power supporting effect of the distributed power supply are utilized, and power supply of
