For the purpose, a novel hybrid optimization algorithm, which combines chaos optimization algorithm (COA) and linear interior point method, is proposed. By use of the properties of intrinsic ergodicity, stochastic property, and regularity of chaos, the chaos optimization algorithm can escape from the local minima and approach the global minima. To improve the rate of convergence and accuracy, the linear primal-dual interior point method with the predictor-corrector is used to perform the local search in the neighborhood of the global minima. Through the numerical calculation for IEEE 14, 30 and 57 bus test systems, the effectiveness of the presented algorithm is validated.
