Synthetic Power System Models for PSS Tuning and Performance Assessment

This paper presents four low-order synthetic power system models for the tuning and performance assessment of power system stabilizers (PSS). Each synthetic system comprises a family of two or three-bus power system models in which one or more parameters are changed in order to reproduce oscillatory poles in the whole range of the typical electromechanical frequencies, from the intra-plant to the inter-area. PSS tuning requirements are compared for synthetic systems of variable and fixed transmission angle, variable generator size and variable equivalent grid inertia.
