Dynamic control of a unified power flow controller

Abstract

The performance of a unified power flow controller (UPFC) with four different controllers is evaluated through simulation and implementation in an experimental laboratory model. The controllers which were investigated are the PI controller, PI controller with decoupling, cross-coupling controller and robust H/spl infin/ controller. It is found that the cross-coupling and robust H/spl infin/ controllers have the best performance when the exact value of the power transmission parameters are unknown.
