| Abstract | ||||
| This paper teals with aproblem of dynalaic instability facing a real power system. Evidence of a problem arose in studies of a proposed generationexpansion of the system using a comprehensive nonlinear dynamic simulation for the system. The procedure followed to stabilize such non-linear system was to linearize the system into state space form and to use modal control approach and an optimization approach to design the stabilizers. Two alternative solutions are illustrated; the first is based on the centralized approach in which a single stabilizer controlling the whole system is designedoand the second is based on a decentralized approach in which local-controllers are designed for the individual machines. Dynamic simulation tests, again on the non-linear dynamic simulation confirm the effectiveness of the alternative approaches. | ||||
