Abstract

The authors present a method of coordinating multiple adaptive power system stabilizer (PSS) units in a power system. The method is based on a decentralized adaptive control scheme. Self-tuning adaptive controllers are used as PSS units on given generators. The generators that tend to strongly dynamically interact are coordinated by communicating the controlled inputs between them. The communicated information is used in such a way that the controllers are robust to any communication failures. Simulation results that compare noncoordinated controllers with coordinated ones are presented for a 17-machine system. Two different system operating points were tested. It is shown that better system damping is obtained if the adaptive PSS units on the strongly coupled generators were coordinated
