Distribution Network Reconfiguration Based on the Combination of Adaptive Genetic Algorithm and ant Colony Algorithm

The economics,power quality and reliability of distribution system operation can be improved through the combinative optimum of the switches.The article is based on the combination of adaptive genetic algorithm and ant colony algorithm to reduce the line loss,improve system voltage and optimize speed.The end adaptive genetic algorithm and is based on the concept of Chromosome similarity,Population similarity and the adaptive adjustment to the crossover rate and mutation rate,not based on the set maximum iteration.the combination of adaptive genetic algorithm and ant colony algorithm is based on the rapid global search capability of genetic algorithm and convergence of positive feedback mechanism of ant colony algorithm,beginning use adaptive genetic algorithm to produce pheromone distribution,then use positive feedback mechanism of ant colony algorithm to seek exact Solutions.Thus time efficiency of the combination of both algorithm is superior to the ant colony algorithm,Finding exact solutions in the efficiency of genetic algorithms better than that.As far as a new intelligent algorithm be concerned,time and efficiency have it both ways.At last,the simulation result of the IEEE69 note system verified the efficient and feasible of the algorithm.
