Description

technical field [0001] The present invention relates to the technical field of restoring power supply, in particular to a method, device, electronic equipment and storage medium for restoring power supply. Background technique [0002] Failure process simulation of key components of the power grid, consequence simulation deduction, and power grid optimal recovery plan calculation are one of the key issues in building a digital twin power grid and improving power grid analysis and accident emergency response capabilities. At present, there are patents related to the risk analysis of equipment failure consequences and the analysis of the optimal path of power restoration after an accident, which can realize the analysis of the consequences of a single equipment failure, and can also realize the calculation of possible power restoration schemes in a given post-failure operation mode. [0003] At present, the existing fault analysis methods for simulating key equipment have the ...
