This paper presents an adaptive LOG control strategy 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 SVC 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 on-line by a least squares identifier. Simulation results for a nine bus network are presented.
