A comprehensive review of damping of low frequency oscillations in power systems

Abstract

The low frequency electromechanical oscillations, with frequency ranging from 0.1-3Hz, are inherent to electric power systems. The low frequency oscillations are related to the small signal stability of the power system and are detrimental to the goals of maximum power transfer and power system stability. Problems due to inadequate damping of such oscillations have been encountered through the history of power systems. This paper presents a comprehensive overview of damping of low frequency oscillations in power systems.
