Adaptive Stabilization of Multimachine Power Systems Through Decentralized Eigenvalue Estimation and Assignmen

This paper will investigate the possibilities of decentralized modal (eigenvalue) control of multimachine power systems. An adaptive power system stabilizer will be used for local electro-mechanical eigenvalue estimation and assignment. The coordination of the adaptive controllers will be realized through the continuation method of decentralized pole placement in a multimachine environment. A three machine system example will illustrate the developed concepts.
