Ship grid reconstruction method based on ring topology gauss dynamic particle swarm optimization algorithm

Abstract

The invention discloses a ship grid reconstruction method based on a ring topology gauss dynamic particle swarm optimization algorithm and belongs to the field of swam intelligent computing. The ship grid reconstruction problem essentially belongs to multi-target multi-variable dispersing, optimization and combination problems. The defects that in the prior art, computing time is long and an unsatisfied solution can be easily searched exist when the ship grid reconstruction problem is solved, and special requirements of ships for security and instantaneity are difficult to meet. The ring topology is introduced into a dispersed GDPS optimization algorithm, information communication among particles is made to be relatively slow, the influence on other particles is small when a few of particles drop in a local extreme value, and therefore searching for the globally optimal solution is more facilitated. Meanwhile, the ring topology is relatively simple, and the computing time can be obviously shortened. According to the method, population diversity can be kept in the whole searching process, and the globally optimal effect can be more rapidly and better obtained.

Description

technical field [0001] The invention relates to a method for reconfiguring a ship power grid based on a ring topology Gaussian dynamic particle swarm optimization algorithm, belonging to the field of group intelligent computing. Background technique [0002] The ship power system is significantly different from the land power system, so the power grid reconfiguration problem is different from the distribution network reconfiguration of the land power system, and has the following characteristics: Compared with the land power system, the power line of the ship power system is shorter and the impedance It is very small, and its active network loss is negligible; the main goal of ship power grid reconfiguration is to maximize the continuous power supply to high-priority loads and maintain the most basic load demand of ships when a fault occurs or battle damage occurs; There are some important loads in the power system that must ensure continuous power supply, and the grid recon...
