© 2019 IEEE. The power system is inherently a complex nonlinear system and experiences continuous changes in operating conditions due to sudden variations in load demand. The increasing integration of renewable power sources in current grids brings new dynamics and increases complexity in developing reliable control strategies. In addition, the variability of renewable generation introduce uncertainty and therefore, an advanced controller is required to ensure the systems stability. The wide area measurement systems (WAMS) has made the remote signal much readily available, thus improving the overall systems observability. With considering the changing systems dynamics, an output feedback model reference adaptive damping controller is designed and implemented in this paper. The results show the controllers effectiveness to handle the parametric and nonparametric uncertainties of the system while obtaining satisfactory damping action on inter-area oscillations.
