Abstract :
A controllable series capacitor (CSC) with suitable control schemes can improve power system transient stability and help to damp electromechanical oscillations. This paper examines the improvement of power system dynamics when a CSC is controlled by either a control Lyapunov function (CLF) or variable structure control (VSC). The effectiveness of the proposed control laws are demonstrated in a single machine infinite bus (SMIB) power system.
