A synthetic system for the robustness assessment of power system stabilizers

This paper describes a method for the robustness assessment of the generator-voltage regulator-stabilizer set of individual power plants in large scale systems. This is carried out using a 2-bus synthetic system, whose parameters are varied to simulate the presence of electromechanical oscillations over a wide range of frequencies. The method helps predicting the generator-voltage regulator-stabilizer performance, when submitted to electromechanical oscillations of different nature (interarea, local and intraplant) in the actual multimachine environment.
