Abstract

The invention discloses a distribution network resource repair optimal scheduling method based on a tabu search algorithm. According to the distribution network resource repair optimal scheduling method based on the tabu search algorithm, a plurality of factors of repair resource scheduling are comprehensively considered, a repair resource optimal scheduling model is established, and a global optimal engine based on the tabu search algorithm relates to the specific operations of a neighborhood, a tabu list, a tabu length and an amnesty rule. According to the method, the disadvantage that a highly-efficient repair resource optimal scheduling strategy is difficult to make with human experiences caused by the factors of a complex distribution network structure, complex branches and multiple involved repair resources is overcome, the working efficiency of fault repair and the utilization efficiency of the resources are improved, thus the time of fault recovery is shortened, and the customer satisfaction is enhanced.

Description

technical field [0001] The invention belongs to the technical field of distribution network resource scheduling algorithms, and in particular relates to a distribution network resource emergency repair optimization scheduling method based on a tabu search algorithm. Background technique [0002] At present, the optimal scheduling method of emergency repair resources in distribution network is mainly genetic algorithm. Carry out genetic coding for the fault location, then perform crossover, selection, and mutation operations on the population, and perform fitness evaluation, and iterate repeatedly to obtain the best emergency repair plan, and finally decode the genetic code to generate an optimal scheduling strategy for emergency repair resources, so that the grid power failure load is minimized or The repair path is the shortest. [0003] The existing optimal dispatching methods mainly aim at the size of the outage load, but seldom consider multiple factors comprehensively,...
