Abstract :
The design of power system stabilizers using linear quadratic Gaussian regulator methodology with loop transfer recovery (LQG/LTR) is considered. A one-machine infinite-bus system is used to test the effectiveness of the proposed stabilizer. The stabilizer is designed using a low-order linear model of the power system. A computer simulation was performed with a complete high-order nonlinear model. It is shown that the closed-loop system with the proposed stabilizer is very robust; i.e. it remained stable for a large amount of disturbance and/or perturbation
