非线性同伦参数在不可行性探测中的数值分析

Infeasibility Detection of Optimal Power Flow Problem

以发电机的有功耗量作为目标函数,以发电机功率输出的上下限、节点电压的上下限作为变量型不等式约束条件,以节点潮流方程作为等式约束构成最优潮流的数学模型,运用非线性同伦内点法求解最优潮流问题.对IEEE6、IEEE118节点试验系统的计算表明,其计算结果与运用内点法所得的结果十分接近,同时能够及时探测出不可行情况.

<Abstrcat> In this paper,the active power of the generator was used as objective function,the up and down limits of the output of power and the bus-voltage were used as the restrictive condition,and the bus-flow function was used as the mathematics model of optimal power flow.nonlinear homogeneous interior method was used to solve the optimal power flow problem.The numerical computation on Ward & Hale 6-bus and IEEE 118-bus test systems showed that the result based on the proposed algorithm is close to the result based on interior point method and this algorithm can detect infeasibility conditions in immediately.
