Distributed power distribution network fault positioning method based on improved grey wolf optimization algorithm

The invention relates to the technical field of power distribution network fault positioning, in particular to a distributed power distribution network fault positioning method based on an improved grey wolf optimization algorithm, and the method comprises the steps: constructing a switching function capable of adapting to multi-power switching for each node of a power distribution network; based on the switching function of each region of the power distribution network, analyzing the association relationship between the section state and the switching state of each region, and further realizing hierarchical division of the power distribution network and generating a corresponding power distribution network hierarchical model; introducing crossover operation and mutation operation into the position updating model of the grey wolf optimization algorithm to generate a corresponding improved grey wolf optimization algorithm; positioning a fault area in the power distribution network hierarchical model through an
