A novel wide-area control for general application to inverter-based resources in power systems

The article illustrates the wide-synchronization control, a novel wide-area control for general application to inverter-based resources. The principle is first introduced from a theoretical point of view, including a mathematical proof of the concept, a technological assessment of grid-following and grid-forming converters as actuators, and the examination of the effects of the latencies. The wide-synchronization control is then demonstrated with the application to two case-studies, the standard two-area benchmark system and the large-scale European power system. Analysis and results indicate that the proposed control can remarkably improve the dynamic characteristics of the system, securing a stable operation with a high degree of flexibility and even under critical conditions.
