H∞ design of wide-area controller for damping inter-area oscillation in power system

This paper demonstrates synthesis of a robust wide-area controller for damping inter-area power system oscillation. A wide-area damping controller is more effective in damping inter-area modes in power system as it takes remote signal as feedback in which inter-area oscillations strongly observable. However, with the involvement of remote signal time-delay is introduced in the feedback loop causing limitation in performance and design. An H∞ controller with regional pole placement controller is designed in this paper. Time-delay is Pade approximated for controller synthesis. Finally, the designed controller is validated through a two-area power system.
