Robust decentralized turbine/governor control using linear matrix inequalities

Abstract

A new scheme is presented for the robust decentralized stabilization of multimachine power systems, based on linear matrix inequalities (LMI). The proposed method is computationally efficient and can easily incorporate additional design requirements. The efficiency of this control strategy is illustrated on the IEEE 39 bus system for a variety of large disturbances. Experimental results indicate that transient stability can be significantly improved with this approach.
