A Power System Stabilizer (PSS) is a complementary excitation controller used in the synchronous generator for damping electromechanical oscillations present in an electric power system. The PSS is a dynamic system subject to disturbances and uncertainties, which can lead to unstable system operating conditions. In this paper, a robust stability test is proposed to found the stability bounds for a family of PSS using an unstructured modeling approach. The proposed test is verified using computational simulations. The results obtained show the parameters that are more sensitive to disturbances and that may cause the system to lose stability.
