Dynamic Frequency Support from a DFIG-Based Wind Turbine Generator via Virtual Inertia Control
Applied Sciences, 2020 As the penetrated level of wind in power grids increases, the online system inertia becomes weak. Doubly-fed induction generator (DFIG)-based wind turbine generators (WTGs) are required to provide virtual inertia response to support system frequency. The
