A dissipativity-based approach to the decentralized analysis of power systems stability

This paper describes a dissipativity-based methodology for the stability analysis of power systems. Sufficient conditions for dissipativity assessment which are based on classical results of the control theory are introduced. These conditions allow conclude the dissipativity of the overall power systems from decentralized dynamic information. The overall stability analysis is shown to need additional information on interconnected dynamics. The decentralized dynamical tests are shown to be easy to verify for several classical power system models.
