Adaptive Synthetic Inertia Control Framework for Distributed Energy Resources in Low-Inertia Microgrid

IEEE Access, 2022
Bulk integration of Distributed Energy Resources (DERs) into the power grids reduces the system’s inherent inertial response.The reduced inertial response causes a high Rate-of-Change-of-Frequency (RoCoF) and poses formidable operational ...
