Disturbance decoupling control of the swing equations

Abstract

This paper initiates an investigation of the application of nonlinear disturbance decoupling theory to the emergency control of electric power systems. The nonlinear classical swing equation model for a network of generator buses is employed. A complete characterization of the set of decoupling feedback controllers is presented. The disturbances considered are generation and load loss, and the control mechanism employed is variation of mechanical input power.
