动态经济调度（DED）在电力系统运行中发挥着重要作用，是一个复杂的非线性约束优化问题。考虑机组阀点效应后，该方程具有非光滑、非凸的特性。提出了一种改进的差分进化算法（MDE）来求解具有阀点效应的DED问题。在所提出的MDE方法中，可行性为基础的选择比较技术和启发式搜索规则的设计，有效地处理约束。与惩罚函数法相比，约束处理法不需要惩罚因子或任何额外的参数，可以快速地将种群引导到可行域。特别地，它可以精确地满足DED问题的等式约束。此外，两个关键参数的影响，以及对性能的MDE DED问题进行了研究。应用实例验证了该方法的可行性和有效性，并与文献报道的其他方法的测试结果进行了比较。结果表明，该方法是能够产生更高质量的解决方案。
Dynamic economic dispatch (DED) plays an important role in power system operation, which is a complicated non-linear constrained optimization problem. It has nonsmooth and nonconvex characteristic when generation unit valve-point effects are taken into account. This paper proposes a modified differential evolution approach (MDE) to solve DED problem with valve-point effects. In the proposed MDE method, feasibility-based selection comparison techniques and heuristic search rules are devised to handle constraints effectively. In contrast to the penalty function method, the constraints-handling method does not require penalty factors or any extra parameters and can guide the population to the feasible region quickly. Especially, it can be satisfied equality constraints of DED problem precisely. Moreover, the effects of two crucial parameters on the performance of the MDE for DED problem are studied as well. The feasibility and effectiveness of the proposed method is demonstrated for application example and the test results are compared with those of other methods reported in literature. It is shown that the proposed method is capable of yielding higher quality solutions.
