Passivity-based sliding mode control of power systems

A sliding mode decentralized excitation controller for multimachine power system is designed to stabilize the speed and regulate the terminal generator voltages. In order to design a sliding manifold the passivity technique is used. Then, with this manifold a sliding mode integral controller is proposed. This combination enables to reject internal and/or external perturbations and take advantage of the energy properties of the power systems. The designed controller was tested through simulation on an equivalent of WSCC (Western System Coordinating Council).
