Decentralized robust control for FACTS using hankel reduced order models

Abstract

This paper presents a decentralized robust control scheme for two types of FACTS devices: SVC and TCSC, to enhance the voltage and angular stability in a power system. The robust control scheme is based on reduced order models, which are computed using the Hankel reduction theory. After that, computation of decentralized robust controls is proposed and tested in a two-area 68 nodes system.
