【摘要】 内点法已成功的应用到无功优化当中,但当不存在所有满足等式和不等式约束的解时,内点法就是不可行的。本文对原对偶内点法的不可行问题进行了研究,通过借助于约束的对偶变量和互补间隙提供的信息进行不可行探测,并将互补间隙作为惩罚项引入目标函数,解决了不可行问题。算例结果通过与非线性内点法相比较证明,本文算法较好对不可行问题进行探测和处理。更多还原

【Abstract】 Interior point has successfully applied to reactive power optimization,but when the solution satisfied all of the equality constraints and inequality constraints don’t exit,infeasibility occurs.This paper made study on infeasibility of primal-dual interior point method and detected infeasibility by means of dual varieties and complementary gap,furthermore,proposed a new algorithm incorporating complementary gap as penalty function.Results of test systems in comparison with that of conventional algorithm demonstrate the proposed method can effectively detect and solve infeasible problem.更多还原
