Coordinated Switching Controller Design for the Power System with SVC and Steam Valve

For the single-machine infinite-bus steam valve system, the coordinated control problem of SVC and steam valve sliding mode is addressed by means of backstepping method with the control input constraints. In the design process, the non-linear features are kept without any linearization used here, thus improving effectively the transient stability of power system even under the effect of the mechanical disturbance and short-circuit faults in power system. Also by introducing switching mechanism, we solve the problem of the control input constraints. Simulation results prove the effectiveness of the proposed controller in this paper.
