Abstract

A decentralized control system for stabilizing a longitudinal power system is studied. The system is designed by a design methodology proposed earlier for decentralized control. In the process of the design, it is found that only the control information of phase angles from other areas is indispensable for maintaining the system stability. New measurements of the tieline power flow are substituted for the indispensable information. Simulation studies demonstrate that the resulting decentralized control system using tieline power flow measurements has as excellent performance in enhancing the stability of a longitudinal power system as a centralized control system
