Abstract

This study presents discusses the small-signal stability analysis of the application of a unified power flow controller (UPFC) to enhance the damping of low frequency oscillation (LFO) in a single-machine infinite-bus (SMIB) power system. A UPFC supplementary damping controller design using a fuzzy logic schemes is considered to enhance damping. The advantages of the proposed method are their feasibility and simplicity. To show effectiveness of fuzzy approach in damping power system oscillation, the proposed method is compared with a conventional method (lead-lag compensation). Validity of the proposed method has been confirmed by linear time-domain simulation results.
