Abstract :
The scope of this paper is to show that an extended quasi-steady-state model of long-term dynamics that includes low-frequency interarea oscillations can be used effectively for the design of power system stabilizers (PSSs). All local and intra-area electromechanical oscillations are replaced in this model by equilibrium (algebraic) equations. In addition, prime mover models are reduced by eliminating one state variable. The proposed model is applied to several operating points of an 11-bus, four-generator test system commonly used for interarea oscillation studies. The PSSs designed using the simplified model provide adequate interarea damping for all operating points without affecting oscillation frequency. These results are verified through detailed system simulation.
