This application relates to the field of power system emergency control technology, specifically to a method and system for generating rolling clearing schemes for post-disaster distribution network recovery. The method includes: acquiring real-time data of the distribution network; constructing a context feature vector for the current moment, inputting it into a pre-trained decision generation network for forward inference, and outputting a preliminary clearing decision within a rolling window; using a pre-trained physical feasibility discrimination network to perform security verification on the preliminary decision; if the confidence level is lower than a threshold, correcting it through linear projection to obtain the final clearing decision; issuing and executing the first step instruction in the final clearing decision, and then rolling the decision time to the next time step for cyclical execution. The decision generation network and the discrimination network are co-trained using a simulation dataset, which is generated by solving a single-leader-multiple-follower model reconstructed from a post-disaster recovery single-layer mixed integer linear programming model. This invention enables dynamic closed-loop adjustment and rapid generation of post-disaster recovery schemes.
