Deployment and Operational Experience of an Adaptive Wide-Area Damping Controller at the Italian Power Grid to Mitigate Continental Europe North-South Mode Oscillations

A growing number of oscillation events are being observed in large-scale power grids around the world. For instance, on December 3rd 2017, the Continental Europe Synchronous Area system (CESAS) was operating under an unusual low-loading condition, and two consecutive generation disconnections due to regular market operation excited a sustained 0.293 Hz oscillation of the well-known North-South mode, which lasted for more than 10 minutes.
