Abstract: In this paper, the robust excitation control strategies for single-machine infinite bus power system are studied and compared. Effort has been concentrated on comparisons between the linear guaranteed cost robust control strategy and the non-linear robust passive control strategy. It is shown through simulations that both the strategies are effective in improving power system transient stability under bounded uncertainties, but the linear strategy experiences a sustained low-frequency oscillation and on the other hand, the non-linear strategy results in a very complex control law and presents a peaking phenomenon.
Keywords: linear guaranteed cost control; nonlinear passive control; single-machine infinite bus power system; stability; robust control; excitation control.
