Abstract

Under some circumstances, conventional power system stabilizers (PSS) suffer shortcomings and cannot enhance small-signal stability of the power systems especially when it comes to inter-area oscillation damping. This along with the advanced technology in phasor measurement units (PMUs) has lead to an increasing interest in developing global controllers using wide-area measurements to solve the deficiencies of local PSSs. The focus of this paper is to use fuzzy logic principles to develop supervisory power system stabilizers (SPSS) to enhance damping of inter-area oscillations to improve stability and reliability of power systems subjected to disturbances.
