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 algo-rithm 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.
