摘　　要：将一种改进的Tabu搜索算法用于电力系统的无功优化,建立了相应的数学模型,并以有功网损为目标函数。在传统的Tabu搜索算法的基础上,对补偿电容分组投切的二进制优化编码、退出迭代的判定条件、Tabu表深度、不同循环起点的选择等问题做了分析讨论,使得更容易跳出局部最优解,保证可以搜索整个可行域,从而得到最优解的可能性更大。应用改进的Tabu搜索算法对IEEE6节点系统进行了无功优化实例计算,结果表明改进的Tabu搜索算法具有更强的全局寻优能力。A modified Tabu search algorithm is applied to power system reactive power optimization and a corresponding mathematical model is established in this paper in which the cost for line losses are considered to be minimun. On the basis of general Tabu search algorithm are analyzed and some corresponding improvements are made, thus, it is easily to stop the iteration of patial optimization and it is more probable to achieve the globe optimization by use of modified Tabu search algorithm. Comparing the optimized result for IEEE6 system by modified Tabu search algorithm with that by Tabu the result shows that modified Tabu search algorithm performs better in global optimization.
