Interconnected power systems are subject to low frequency oscillations. These oscillations, if poorly damped, threaten the stability of the system and limit its power transfer capability. Power System Stabilizers (PSS) are widely used to enhance the damping of electromechanical oscillatory modes. Conventional methods to tune power system stabilizers attempt to provide the required magnitude/phase shift compensation through frequency response or mode sensitivity analysis. However, these methods do not operate directly on the damping sensitivity of the mode. A novel method to calculate the damping sensitivity has been developed in this work. It operates on mode damping directly to achieve optimum damping for the under-damped oscillatory modes. The proposed method has been used to tune simple stabilizers for the well-known two-area four-machine power system problem and the IEEE9-Bus system. It is compared with results obtained from complex and robust PSS designs, and found to offer comparable outcomes.
