• We have proposed application of extremum-seeking control to design power system damping controller.
• SVC supplementary controller has been designed based extremum-seeking control theory.
• Designed controller is compared with H loop-shaping based controller.
• Effect of ditcher frequency and adaption gain on the performance of the controller is also demonstrated.

This paper presents an application of extremum seeking control to stabilize power system oscillations. This control methodology has been implemented as a supplementary control to Static Var Compensator for providing additional damping to power systems. The performance of the designed controller based on extremum seeking method has been compared with the controller based on H loop-shaping technique. With time domain simulations it has been shown that the controller based on extremum seeking methodology successfully reduces power system oscillations earlier than that with the H loop-shaping methodology. The effect of dither frequency and adaption gain on performance of extremum seeking controller has also been examined. The 14-Generator South East Australian equivalent power system has been used as a test system to demonstrate the ability of extremum seeking controller to reduce power system oscillations.
