Multi-period robust fault recovery method for power distribution network

The invention discloses a multi-period robust fault recovery method for a power distribution network. The method comprises the steps of S1, acquiring and utilizing historical data of new energy output to establish an ellipsoid uncertainty set; s2, constructing a convex hull polyhedron uncertainty set on the basis of the ellipsoid uncertainty set; s3, constructing a power distribution network multi-period fault recovery model; s4, on the basis of the power distribution network multi-period fault recovery model and the convex hull polyhedron uncertainty set, establishing a power distribution network two-stage robust fault recovery optimization model; and S5, solving the two-stage robust fault recovery optimization model of the power distribution network, and outputting an optimization result. According to the method, the robustness of the system can be improved, the total fault recovery amount and the load recovery amount of the convex hull polyhedron set system are better than those of a box type set, the cons
