DC最优潮流问题的最坏情况灵敏度

Worst-Case Sensitivity of DC Optimal Power Flow Problems

James Anderson, Fengyu Zhou, Steven H. Low

摘要:

在本文中,我们考虑的问题,分析的影响,在负载矢量的变化可以在直流潮流模型的最佳发电。该方法是基于最近推出的概念的$\mathcal{OPF}$运营商。结果表明,对于一般的网络拓扑结构计算的最坏情况下的灵敏度是计算棘手的。然而,我们表明,某些问题涉及的$\mathcal{OPF}$运营商可以等价地转换为一个图形的离散最优化问题。使用离散公式,我们提供了一个分解算法,降低了计算最坏情况下的灵敏度的计算成本。一个27节点的算例来说明我们的结果。

英文摘要:

In this paper we consider the problem of analyzing the effect a change in the load vector can have on the optimal power generation in a DC power flow model. The methodology is based upon the recently introduced concept of the $\mathcal{OPF}$ operator. It is shown that for general network topologies computing the worst-case sensitivities is computationally intractable. However, we show that certain problems involving the $\mathcal{OPF}$ operator can be equivalently converted to a graphical discrete optimization problem. Using the discrete formulation, we provide a decomposition algorithm that reduces the computational cost of computing the worst-case sensitivity. A 27-bus numerical example is used to illustrate our results.
