摘　　要：在原对偶对数障碍法的基础上,提出一种改进算法用于解决最优潮流问题.利用障碍参数对改进障碍函数的影响,使改进算法能有效地处理最优潮流问题中的不等式约束,避免了计算中对有效约束的识别问题.将改进算法与原有算法用于IEEE 30节点系统无功优化问题的仿真计算,结果证明了改进方法是有效可行的,且与原有方法相比,可求得更优解.Based on the primal-dual logarithmic-barrier method, a novel method for optimal power flow problem is presented in this paper. The barrier function is improved in the modified primal-dual logarithmic-barrier method which solves the constrained optimization problem and avoids the identification problem to the active constraints boundary. The simulation results of reactive power optimization for IEEE 30-bus system demonstrate the effectiveness and feasibility of the proposed method.
