Eigenvalue Sensitivities for Design of Power System Damping Controllers

Abstract

This paper presents a comprehensive review of methods to compute eigenvalue sensitivities in large linear dynamic systems. Sensitivities with respect to parameters of feedback controllers are of interest since they are suggested as tools for controller design in such demanding environment. These methods have been developed in the context of small-signal stability of electric power systems and the design of damping controllers. The paper also presents new results obtained in the development of expressions of eigenvalue sensitivities with respect to parameters of damping controllers of series FACTS devices.
