Abstract

The rate of dissipation of transient energy is usually used as a tool to measure dynamic system damping. This paper applies and discusses the above control strategy for suppressing undesirable electromechanical oscillations in power system with a STATic synchronous COMpensator (STATCOM), static synchronous series compensator (SSSC) and unified power flow controller (UPFC). A single machine infinite bus power system was studied over a several disturbance. The obtained results show the effectiveness and robustness of these devices on power system stability.
