Power distribution network feeder automation terminal configuration method based on multiple intelligent algorithms

Abstract

The invention discloses a power distribution network feeder automation terminal configuration method based on multiple intelligent algorithms. The power distribution network feeder automation terminalconfiguration method comprises the following steps: (1) inputting data required by power distribution network feeder automation terminal configuration; (2) randomly generating a plurality of feeder automation terminal configuration schemes to form an original population; (3) calculating the fitness of each individual in the population; (4) selecting an individual with the minimum objective function value in the current population, and updating a historical optimal solution; (5) judging whether a set number of iterations is reached or not, if yes, outputting a current historical optimal solution, and ending optimization; if not, executing the step (6); and (6) performing operation according to the optimization rules of different intelligent algorithms, and generating a new population on the basis of the previous generation of population. And then skipping to the step (3). The power distribution network feeder automation terminal configuration method can provide a more scientific and reasonable power distribution network feeder automation terminal configuration scheme, and can avoid the situations of feeder automation terminal configuration redundancy, investment waste and the likeon the premise of ensuring that the power supply reliability reaches the standard.
