Wide-area damping control schemes with grid-forming as actuators

This paper explores the use of grid-forming converters as actuators for wide-area damping control, relying on a novel control strategy termed Wide-Synchronization Control (WSC). The proposed WSC adopts a centralized architecture, where frequency measurements collected from phasor measurement units are used to compute a global feedback signal, defined as the system average frequency. This signal is broadcast to participating grid-forming converters, which extend their synchronization loop to process the remote reference. By acting on the difference between the local converter frequency and the wide-area average frequency, the
