摘要
针对内点法处理离散变量比较困难,以及和声搜索算法随机性强、方向性差等缺点,在充分利用内点法寻优速度快和和声搜索算法局部搜索能力强的基础上,提出一种改进和声搜索(improved harmony search,IHS)算法的电力系统无功优化新算法。采用IHS算法进行优化,可有效规避内点法处理离散变量困难的问题,并加快了和声搜索算法的收敛速度,提高其寻优能力。以IEEE算例验证了IHS算法具有更强的寻优能力,更快的收敛速度。
In allusion to defects of interior point method being difficult in dealing with discrete variables and strong random and bad directivity of harmony search algorithm,a kind of new algorithm for reactive power optimization of power system based on improved harmony search（IHS）was proposed on the basis of fully using rapid optimizing speed of interior point method and strong capacity of partial searching of harmony search algorithm.It was effectively to avoid problem of being difficult in dealing with discrete variables by interior point method and speed up convergence speed of harmony search algorithm and improve its optimizing capacity by using IHS algorithm for optimization.IEEE example was used for verifying stronger optimizing capacity and faster convergence speed of IHS algorithm.
