This paper presents the design of two decentralized state-feedback controllers to ensure system stability and voltage regulation in multimachine power systems. The power system is decomposed in n subsystems each of them contains a generation node. Two state-space models for each subsystem are proposed both presenting parameter uncertainties while the couplings between the others generators through the transmission lines are modeled as time functions. The controllers are sequentially designed and counteract the effects of model input disturbances. The proposed design is simple to apply and does not require to solve difficult equations. Numerical results obtained on 2 machines power system test show the performance exhibit by the designed controllers in presence of severe contingencies.

Abstract

This paper presents the design of two decentralized state-feedback controllers to ensure system stability and voltage regulation in multimachine power systems. The power system is decomposed in n subsystems each of them contains a generation node. Two state-space models for each subsystem are proposed both presenting parameter uncertainties while the couplings between the others generators through the transmission lines are modeled as time functions. The controllers are sequentially designed and counteract the effects of model input disturbances. The proposed design is simple to apply and does not require to solve difficult equations. Numerical results obtained on 2 machines power system test show the performance exhibit by the designed controllers in presence of severe contingencies.
