| 摘 要： | 通过研究拉格朗日乘子的特点，结合电力系统支路参数特性，本文解决了牛顿法最优潮流算法海森矩阵元素合理常数化问题，在此基础上，提出了快速解耦牛顿法。该算法在选代过程中不必重新形成扩展海森矩阵的因子表，显著地缩短了每次选代时间。本文讨论了不同解耦方式对最优潮流的收敛性影响。计算实例表明，本文算法的收敛性好。

| Abstract: | By researching the characteristics of the lagrangian multipliers of power flow equations and the ratio relationship between resistance and reactance of both transmission lines and transformers,the problem how to make Hessian matrix elements in Newton OPF constant is solved.Based on this,a fast decoupled Newton optimal power flow(FDOPF)algorithm is presented.In this method it is not necessary to recompute the two sparse decoupled Hessian matrices during iteration therefore the execution time for one iteration process is extremly shortened.The effects of decouplins and modifying schemes on convergency of FDOPF is studied.The convergency of FDOPF is almost as the same as md decoupled power flow. |
