Abstract

An optimal controller for damping of sub synchronous resonance (SSR) due to a series compensated line connected to a DFIG-based wind farm is presented in this paper. The design procedure includes system modeling, analysis of sub synchronous phenomena, linearization of system about an operating point and controller design. The proposed controller is designed based on LQR method and the eigenvalue analysis is utilized to describe the behavior of system. IEEE SSR first benchmark used to show the effectiveness of the proposed controller.
