Conservative linear line flow constraints for AC optimal power flow

2017 IEEE Manchester PowerTech, 2017
The AC optimal power flow problem is a non-convex optimization problem that is difficult to solve quickly and reliably for large-scale grids. To enable the application of efficient and robust solution algorithms, various linear approximations of the nonlinear system model are used.

A Feedback Linearization Based Unified Power Flow Controller Internal Controller for Power Flow Control

Electric Power Components and Systems, 2012
Abstract This article presents a feedback linearization based controller design methodology for a unified power flow controller to achieve rapid reference signal tracking in the internal control level. Feedback linearization is a non-linear control technique based on the differential geometry theory and overcomes the drawback of traditional linear ...

On the Formulation of Power Distribution Factors for Linear Load Flow Methods

IEEE Power Engineering Review, 1981
Fast linear load flows used in contingency analysis, interchange studies and many optimization schemes often utilize power distribution factors. The success of many of these methods has hinged greatly on the use of the Z matrix reference to swing or an arbitrary ground tie. This paper furnishes a mathematical basis for these heuristic methods.
