最优潮流的一种新方法

A New Method of Optimal Power Flow

对于最优潮流的求解,本文采用变尺度法。在求解过程中,根据拉格朗日乘法构成增广目标函数,涉及到目标函数的一维搜索、梯度的计算和单位矩阵的迭代等。最后通过一个算列,与传统的牛顿拉夫逊法进行比较,从而验证了新算法的优越性。

DFP is adopted to solve the Optimal Power Flow.In the calculate process,this paper adopts Lagrange multipliers and penalty function method to constitute the objective function augmented,it related to the one-dimensional search,the gradient calculation and so on.Proposed approach is examined on one system.The results show that new method has the advantage over Newton method.
