Improved control strategy to mitigate electromechanical wave propagation using PSS

This paper addresses the problem of electromechanical wave propagation in power systems. To mitigate this type of disturbance, this paper proposes a remote control strategy that could be applied to power system stabilizers. This strategy is based on wide-area measurements, and exploits the disturbance propagation speed to introduce an extra damping torque simul-taneously with the disturbance arrival. Simulation results show that the application of such strategy improves the power system dynamics.
