针对具有阀点效应的经济负荷调度问题，提出了一种将内点法与差分进化相结合的混合算法。该算法包括两个阶段。第一级在不考虑阀点效应的情况下，采用IPM最小化成本函数。第二阶段考虑阀点效应，利用DE最小化代价函数。DE的初始种群在第一阶段得到的解周围2π/f的窄范围内生成。通过对13台和40台火电机组的三种不同系统进行大量测试，验证了该算法的有效性。该方法优于现有的考虑阀点效应的经济负荷调度方法。
The paper proposes a novel hybrid algorithm connecting interior point method (IPM) and differential evolution (DE) for solving economic load dispatch problem with valve point effect. The algorithm involves two stages. The first stage employs IPM to minimize the cost function without considering the valve point effect. The second stage considers valve point effect and minimizes the cost function using DE. The initial population for DE is generated in a narrow range of 2π/f around the solution obtained in the first stage. The effectiveness of the algorithm is validated by carrying out extensive tests on three different systems involving 13 and 40 thermal generating units. The proposed method outperforms other existing techniques for economic load dispatch considering valve-point effects.
