Global power system control using generator excitation, PSS, FACTS devices and capacitor switching

Abstract

A novel power system control scheme is developed in this paper using a framework for coordinating dissimilar controllers at different locations. The control actions are formulated in the so-called global controller as a set of local controllers, namely the generator excitation controller, power system stabilizer (PSS), unified power flow controller (UPFC) and capacitor switching, which are coordinated to maintain transient angle stability, transient voltage stability and damping of long-term inter-area oscillations following a disturbance. The proposed coordinated control scheme is tested on a nine-bus example system. © 2005 Elsevier Ltd. All rights reserved.link_to_subscribed_fulltex
