Analysis of Inter-Area Damping Enhancement by Static VAR Compensators in Longitudinal Power Systems

Abstract The work reported in this paper synthesizes the main findings of an eigen-analysis-based research programme, aimed at assessing the potential for dynamic stability improvement by means of static VAR compensators. The results of the first phase of this research include the determination of modes that are more controllable by existent SVCs, and the use of modulation controls to damp low-frequency inter-area modes of oscillation in longitudinal power systems.
