本文针对GA算法存在的不足,根据电力系统最优潮流具有典型的有约束,非线性的特点,提出了一种改进型DE算法。通过该算法与基本GA算法在IEEE30节点系统上进行算法检验比较。仿真表明,改进DE算法不仅具有良好的应用效果,还有很高的进化效率,求得目标的成功性也有提高。
In this paper, aiming at the shortcomings of GA algorithm, an improved DE algorithm is proposed according to the typical constrained and nonlinear characteristics of optimal power flow in power system. This algorithm is compared with the basic GA algorithm in IEEE30 node system. The simulation shows that the improved DE algorithm not only has good application effect, but also has high evolutionary efficiency, and the success of the goal is also improved.
