Analysis of sustained oscillations in power systems observed through wide measurements
Wide area monitoring of power systems through synchrophasors is now established technology. There are several ongoing projects throughout the world that utilize WAMS technology for performing online oscillations modes identification. Existing literature concentrate on electromechanical oscillations between generators due to power system events like faults and load generation imbalance. In this paper we analyze a different kind of oscillation that are caused by nonlinearities in control systems. Such oscillations have been observed in the system from time to time, but have remained difficult to characterize. Here an attempt is made to reproduce these oscillation in simulation models.
