Wide-Synchronization Control for Power Systems with Grid-Forming Converters

The article presents a novel wide-area control for power systems with grid-forming converters. The concept of the proposed wide-synchronization control is first introduced, and a theoretical proof is offered. A simple yet effective methodology for the tuning of the control is also derived. The concept of wide-synchronization control is then applied to the actual case of the European power system, taken into examination with an appropriate large-scale dynamic model. The results of the analysis indicate that the proposed wide-synchronization control leads to a considerable improvement of the dynamic characteristics of the system. The aspects related to latencies and energetic requirements are also investigated. A roadmap for further developments of the concept is finally discussed.
