摘　　要：本文介绍了一种改进的自由搜索算法,在搜索优化过程中对搜索半径进行自适应调整,融入了遗传算法中的交叉操作以及精英保留策略,当算法收敛时,对个体进行人为迁移以增加寻优能力。将该算法用于电力系统经济负荷分配,通过实例计算证明了该算法的有效性。The paper presents an improved Free Search algorithm. The searching radius is adaptively adjusted during the searching optimization. The crossover operation in Genetic Algorithm and the elitist strategy is used during the optimization procedure. Besides, in order to improve the optimizing capacity, the individuals are moved into a minimal neighborhood of the Optimal Solution when the algorithm converges. The proposed algorithm is used in the Economic Dispatch problem of power systems. The test results show that the method proposed in this paper is feasible.

关 键 词：经济负荷分配 自由搜索 自适应 交叉
