摘要
以原－对偶内点算法（Ｋａｒｍａｒｋａｒ内点法的一种变形）为基本算法解算最优潮流问题，综合考虑非线性目标函数和约束条件，结合牛顿法最优潮流先进的稀疏矩阵技术，并且提出了一种新的原－对偶内点算法迭代步长选取原则和障碍参数修正策略。算例表明本算法有较好的数值稳定性，优化结果精确，对不等式约束有较强的处理能力，显示了内点算法应用于大规模电力系统优化问题的良好前景。
In this paper, a new OPF algorithm based on Karmarkar's interior point (Ip) method, which is called as Primal-Dual Interior Point (PDIP ) algorithm, is presented.Both the non - linear objective and the non - linear equality and inequality constraints for OPF problems are considered in this optimization method and the implementation of the algorithm is integrated with the advanced sparse matrix techniques of Newton OPF approach. One new way about how to select the computation step-size and to update the barrier parameter in each iteration for the PDIP algorithm is also presented. The numerical results of the IEEE - 30 buses system have shown that the Ip algorithm used for OPF problems has good robustness and can get a more precise solution, besides its strong ability to treat the inequality constraints.
