Abstract :
An adaptive linear quadratic Gaussian control strategy is presented for static VAr compensators to enhance power system damping and stability. The control strategy utilizes only local information to dampen oscillatory modes present in the network. The controller calculates an appropriate value of static VAr compensator susceptance to present to the network at each sampling interval based on a reduced-order model of the power system. The reduced-order model is obtained online by a least-squares identifier. Simulation results for a nine-bus network are presented
