the method comprises the steps of comparing the standard power grid scheme for power grid fault event handling generated based on the standard power grid fault handling strategy knowledge graph with the steps of historical power grid schemes for power grid fault event handling generated based on the historical power grid fault handling strategy knowledge graph one by one, and removing, adding and sequencing all the processing steps in the standard scheme according to the handling sequence and the handling steps of the historical schemes to form a final power grid fault handling scheme.
13. A controller comprising a memory and a processor, the memory storing a computer program, characterized in that the processor, when executing the computer program, implements the steps of the method of any of claims 1 to 6.
14. A computer-readable storage medium, on which a computer program is stored, which, when being executed by a processor, carries out the steps of the method of any one of claims 1 to 6.
