Abstract :
In this paper, robust stabilizing controllers for the synchronous generator speed, series power flows, voltage magnitude and DC link voltage, are designed for a power system with FACTS device (UPFC). To design these controllers combined second order sliding mode (SM) and block control (BC) techniques are implemented. The block control approach is used to design nonlinear sliding manifolds with desired motions. A second SM discontinuous control combined with an exact differentiator is applied to reject perturbations and avoid the chattering effect. The effectiveness of proposed algorithm is illustrated by simulations.
