摘　　要：提出了一种改进的Bat算法,用于寻求火电厂经济调度的最优解。由于火电厂运行同时考虑了热电联产机组的发热量和发电量,因此对于优化工具来说是一个复杂而又巨大的挑战。应用改进Bat方法来提高传统Bat算法的高质量求解搜索能力和搜索速度。这种方法是建立在三个修改的Bat基础上。首先是自适应频率调整,其次是更新速度的最佳范围,第三是良好解的保留条件,目的是改善传统Bat的搜索性能。通过对7、24和48单元系统和IEEE 14总线系统的测试,并与传统Bat方法和其他现有方法的结果进行比较,评价了该方法的有效性。结果表明,该方法是求解火电厂运行优化调度问题的一种有效的元启发式算法。In this paper,an improved Bat algorithm is proposed to find the optimal solution of economic dispatch in thermal power plants.Thermal power plant operation takes into account both heat and power generation capacity of cogeneration units,so it is a complex and huge challenge for optimization tools.Therefore,we apply the improved Bat method to improve the high-quality search ability and search speed of the traditional Bat algorithm.This approach is based on three modifications of Bat.The first is the adaptive frequency adjustment,the second is the optimal range of update speed,and the third is the good solution retention condition.The test results of 7,24 and 48 unit system and IEEE 14 bus system are compared with the results of BAT method and other existing methods,and the effectiveness of this method is evaluated.The results show that the proposed method is an effective heuristic for economic dispatch of thermal power plants.
