提出了一种考虑阀点效应的电力系统经济调度（艾德）问题的新方法。该方法是基于混沌粒子群优化算法（CPSO）和序列二次规划（SQP）技术组成的混合算法。CPSO是算法的主要优化器，SQP用于微调其结果以改进解。所提出的方法被应用到三个不同的情况下的电力系统。通过与已有的考虑阀点效应的艾德问题求解方法的比较，探讨了该方法的经济效果、解的质量、收敛性和计算效率。仿真结果表明了该算法对实际艾德问题的适用性和有效性。(C)2011爱思唯尔有限公司保留所有权利。
This paper developed a new method for solving the economic dispatch (ED) problems considering the valve-point effects in power systems. The method is based on a hybrid algorithm consisting of chaotic particle swarm optimization (CPSO) algorithm and sequential quadratic programming (SQP) techniques. The CPSO is the main optimizer of the algorithm and the SQP is used to fine tune its results to improve the solution. The proposed method was applied to three different cases of power systems. The economic effect, solution quality, convergence property and computation efficiency of the proposed method have been explored through the comparison with the existing techniques for the ED problems considering the valve-point effects. The simulation results demonstrate the applicability and effectiveness of the proposed algorithm to the practical ED problems. (C) 2011 Elsevier Ltd. All rights reserved.
