一种经典法与线性规划结合的无功优化方法

A Reactive Power Optimization of Classic Method Combined with Lincar Programming

提出了一种两阶段无功综合优化模型。第一阶段用无功经济调度的经典法快速求得，只计及无功平衡方程和无功源无功的最优解；第二阶段建立基于敏感度的线性增量模型，用线性规划校正越界的状态变量，使第一阶段所得的最优解逐步过渡到最优可行解。并用算例与有关文献的结果进行了比较。

A tow-stage VAR optimization model is presented in this paper.First.the optimal solution is quickly solved by VAR classic method,which only considers the limitaryconditions of Reactive Power and reactiue power equation and yet linear increment model based onsensitivity is set up and linear programnung is employed to correct the overlimit varlables,Theoptimal resnlts in the tirst stdge are corrected to be feasible.The proposed method has beensuccessful in the sample systems and reai systems.
