最近开发了一种称为和声搜索（HS）的元启发式算法，模仿音乐播放器的即兴创作过程。HS算法已经成功地在一些优化问题。HS算法不需要导数信息，并且使用随机随机搜索代替梯度搜索。此外，HS算法概念简单，参数少，易于实现。提出了一种基于指数分布的改进和声搜索算法来求解经济调度问题。一个13单元的试验系统，考虑到阀点加载的影响，以说明所提出的IHS方法的有效性的增量燃料成本函数。数值结果表明IHS方法具有良好的收敛性。此外，IHS方法的发电成本低于经典HS和最近文献中报道的其他优化算法。
A meta-heuristic algorithm called harmony search (HS), mimicking the improvisation process of music players, has been recently developed. The HS algorithm has been successful in several optimization problems. The HS algorithm does not require derivative information and uses stochastic random search instead of a gradient search. In addition, the HS algorithm is simple in concept, few in parameters, and easy in implementation. This paper presents an improved harmony search (IHS) algorithm based on exponential distribution for solving economic dispatch problems. A 13-unit test system with incremental fuel cost function taking into account the valve-point loading effects is used to illustrate the effectiveness of the proposed IHS method. Numerical results show that the IHS method has good convergence property. Furthermore, the generation costs of the IHS method are lower than those of the classical HS and other optimization algorithms reported in recent literature.
