摘要
Abstract
The dimension scale of complementary pairs is one of important factors affecting the convergence of interior point method. In order to avoid large discrepancy among complementary pairs, a centrality corrections method based on constrained slack variables strategy is proposed. In the proposed method, the maximum of slack variables is curtailed by projection method, by which the numerical problem caused by large discrepancy in complementary pairs is settled fully. The proposed method is applied to generation rescheduling considering static voltage stability and the optimization results indicate that the proposed method has a sound convergence performance even when the current inequality constraint variables are far away from their limits, enhancing the practicability of the interior point algorithm greatly.关键词
