Elastic power distribution network element key analysis method, system, medium and equipment

The invention discloses a critical analysis method and system for elastic power distribution network elements, a medium and equipment. The method comprises the following steps: abstracting vulnerable elements of a power distribution system and a mutual connection relation into a power distribution system graph model based on a graph model theory; modeling is carried out on the power distribution system elements, and the element fault rate and the fault repair time of the potential key elements are determined; performing time sequence Monte Carlo sampling on all elements of the power distribution system to generate an element time sequence state transition sequence; obtaining a time sequence state transition sequence of the power distribution system according to the topological relation among the nodes of the power distribution system graph model; according to the power distribution system graph model and the power distribution system time sequence state transition sequence, analyzing the influence of key elem
