Energy-Storage-Device-Enabled Adaptable Fast/Slow Synchronization Control …
Previous adaptive fast/slow synchronization control methods depended on stiff DC-side sources and may not work in scenarios with limited DC-side power capacity. To address this limitation, the paper introduces an adaptable fast/slow synchronization control structure for a dual-port grid-forming (DGFM) VSC with an energy storage device (ESD).
