摘要
Abstract
In order to solve the problem of distribution network reconfiguration more effectively,an improved bacterial foraging algorithm(BFA)is proposed by combining the characteristics of particle swarm optimization(PSO)algorithm. Firstly,group optimization mechanism of PSO is introduced to BFA. Secondly,considering the defects of BFA in the later stage such as single particle swam and the vulnerability of being easily trapped in a local optimum ,the average variation of reproduction and new dispersal rules are proposed through mechanism analysis,which not only changes the random search of BFA into a guided search but also diversifies the swarm after reproduction,thus the searching speed and global searching ability of the proposed algorithm are effectively improved. Finally,the improved algorithm is ap?plied to distribution network reconfiguration. The simulation result of an example shows that the proposed algorithm can fast and effectively find the optimum solution,thus it is feasible.关键词
