This paper presents the transient stability enhancement of power transmission system with Static Var Compensator (SVC) by adopting immersion and invariant (I&I) methodology in designing SVC adaptive controller. The controlled system is a single machine infinite bus (SMIB) system with uncertain parameters: damping coefficient, mechanical power, generator rotor angle and line impedance. In the proposed SVC controller, a deduced-order target system is first defined and the dynamics of the controlled system will be “immersed” into it based on I&I stabilization. The proposed SVC controller is then made adaptive by designing adaptive update laws based on adaptive sliding-mode observer to identify the uncertain parameters. The simulation results demonstrate the effectiveness of the proposed SVC adaptive controller.
