| 摘 要： | 针对电力系统经济负荷分配本质上的非线性约束优化问题,提出一种双种群混合差分进化算法.采用两个种群且以较小的计算量实现目标函数的寻优并保持解的可行性,同时引入单纯型法来提高算法的局部搜索能力.基于典型算例对该算法的进化行为进行测试,并通过仿真和比较验证了所提出算法的有效性.

| Abstract: | Economic distribution of power systems can be regarded as a non-linear constrained optimization problem.In this paper,a hybrid double-population differential evolution is proposed,which uses two populations to optimize objective function and to maintain feasibility of solutions with a little computational effort.In addition,simplex method is embedded to enhance the exploitation ability.The evolving behavior of the algorithm is tested based on a typical instance.Simulation and comparison show the effectivene... |
