中文摘要：

计及爬坡速率限制、机组禁行区域、阀点效应、网损和多燃料的电力系统经济调度（economic dispatch，ED）模型具有非凸、非线性和不可微特性，近年来国内外大量的学者对该模型的求解进行了研究。提出了一种快速智能协调和声搜索法（FITHS），并将其应用于ED模型求解之中。以经典的6机系统、15机系统以及含多种燃料选择的10机系统为算例，通过与其他方法相比较，结果表明，FITHS比其他算法收敛速度更快，计算时间更短，能得到更小的发电费用值。FITHS用于求解复杂的ED模型是可行的、快速的和有效的。

英文摘要：

Power system economic dispatch （ED） model, considering ramp rate constraints, prohibited operating zones, valve-point effects, transmission losses and multiple fuels, is non-convex, non-linear and non-differentiable, so in recent years a large number of scholars at home and abroad have studied on the model solution. This paper pres- ents a fast intelligent tuned harmony search optimization （FITHS）for the ED model solution, whereby calculation has been conducted for 6-unit system, 15-unit system and 10-unit system with multiple fuel choices. In comparison, the obtained results show that the proposed FITHS is superior to previous methods in convergence speed, calculation time and power cost value, proving that FITHS is feasible, fast and effective in solving the complex ED model.
