Abstract :
A multivariable adaptive LQ control strategy for static VAr compensators is described which can be added to an existing fixed controller to enhance the robustness and effectiveness of the VAr unit in damping power system oscillations. The control strategy uses only local network information to damp oscillations between machines in the network. Simulation results are presented for a nine-bus network. The controller is effective in reducing local machine oscillations even in cases where the oscillatory disturbance is not controllable
