Ring topology Gaussian dynamic particle swarm optimization algorithm-based ship power grid reconstruction method

Abstract

The invention discloses a ring topology Gaussian dynamic particle swarm optimization algorithm-based ship power grid reconstruction method and belongs to the field of swarm intelligent computation. Essentially, the ship power grid reconstruction problem belongs to a multi-target multivariable discrete optimization problem, and in the prior art, the defects of being long in computation time and easy to search non-satisfactory solutions during the processing of ship power grid reconstruction problems and the special requirements of the ships for the safety and instantaneity are difficult to satisfy. According to the ring topology Gaussian dynamic particle swarm optimization algorithm-based ship power grid reconstruction method, a ring topology is introduced in a discrete GDPS optimization algorithm to ensure that the information exchange among particles is relatively slow; when several particles get into local extremum, the influence on the other particles is small so that the search of globally optimal solution is more facilitated. Meanwhile, the ring topology is relatively simple so that the computation time can be remarkably shortened. The method provided by the invention can be used for keeping the swarm diversity in the whole search process so as to obtain quicker and better global optimization effect.

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...
