VSS-GFM: A Voltage-Source-Sustaining Grid-Forming Strategy for Seamless Operation Under Severe Disturbances

Grid-forming (GFM) control strategies face critical challenges in fault response, protection coordination, and grid code compliance. Conventional voltage-controlled GFM (VC-GFM) and current-controlled GFM (CC-GFM) each possess distinct advantages but individually fail to fully address these challenges. This paper systematically analyzes both VC-GFM and
