配电网重构算法的研究

文章对以网损最小为目标函数的配电网重构算法进行了研究，提出一种改进的进化算法进行重构。算法改进了用遗传算法或者差异进化算法进行重构时产生大量不可行解的不足，根据梯度的概念和配电网络的结构特点，对可行解进行加速操作，使之迅速靠近并最终成为一个局部最优解，然后进行移民操作，以保持种群的多样性。最终选择所有局部最优解当中最优的个体为全局最优解。算例结果证明了此算法的优越性，表明该算法有较好的搜索效率。

Research on the Restructuring Algorithm of Distribution Network

Based on the research on the restructuring method in distribution network with the goal function as minimum power loss, the article proposes one improved-computing method with the minimum power loss as the goal function. The improved method eliminates the disadvantages in the genetic algorism and difference reducing algorism. According to the concept of grads and the structural features of the distribution network, the new method can quicken up the pace of solving, have a best partial solving and keep a diversified species group. Consequently, it can produce the best result by choosing among the best partial solving. The experimental resuhs prove volumes of its advantages and its efficiency in search.
