本文提出了一种混合解耦最优潮流方法，旨在实现在线应用的最优潮流程序。利用数学规划理论的部分对偶原理和电力系统中实数潮流与无功潮流之间固有的弱耦合特性，通过交替求解一个实数子问题和一个无功子问题来迭代逼近原优化问题的解。采用两种专门定制的技术，一种是基于线性规划的，另一种是基于二次规划的，分别求解这两个子问题。这种混合特性使得该方法非常灵活，同时保持了解耦的效率。该方法已在东北电力管理局控制中心成功实现在线使用。
This paper presents a hybrid decoupled optimal power flow approach aimed at implementing an optimal power flow program for online applications. By taking advantage of the partial duality principle of mathematical programming theory and the inherent weak coupling characteristics between real and reactive power flows in a power system, the solution to the original optimization problem can be approximated iteratively by solving a real and a reactive subproblem alternately. Two special deliberately customized techniques, one (based on linear programming) and the other (based on quadratic programming), are adopted to solve the two subproblems respectively. This hybrid feature makes the approach very flexible while preserving the efficiency of decoupling. The approach has been successfully implemented for online usage in the Control Center of Northeast China Electric Power Administration.
