Stabilization via interconnection and damping assignment: First order model of the CSC

Abstract

While studying the role of the CSCs for power system stabilization, the dynamics of the CSC can be accounted for by modeling it as a dynamical system. However, for stability studies it is not necessary to have a detailed model. It is adequate to assume that the desired value of the CSC reactance is achieved within a specified time interval. Hence, a first order model is sufficient for this purpose [1]. In this chapter we apply the IDA-PBC methodology to the SMIB system with a CSC, where the CSC is modeled by a first order model and synthesize stabilizing control laws.
