In this paper, a new procedure is developed for designing power system stabilizers under the constraint of sequential stability. This constraint is an important feature of a large scale decentralized control and deals with the property of a design technique that allows the controllers to be adjusted one at a time such that the system remains stable at all times. This constraint is due to the impossibility to adjust all decentralized controllers to the power system simultaneously (due to unavoidable delays in the communication system). The procedure adopts a linearized model of the power system in the state space representation. The stabilizing signal requires the linear feedback of the local variables only. The suggested design procedure is tested on the standard New England 39-bus system.

Abstract

In this paper, a new procedure is developed for designing power system stabilizers under the constraint of sequential stability. This constraint is an important feature of a large scale decentralized control and deals with the property of a design technique that allows the controllers to be adjusted one at a time such that the system remains stable at all times. This constraint is due to the impossibility to adjust all decentralized controllers to the power system simultaneously (due to unavoidable delays in the communication system). The procedure adopts a linearized model of the power system in the state space representation. The stabilizing signal requires the linear feedback of the local variables only. The suggested design procedure is tested on the standard New England 39-bus system.
