Islanding Detection of Grid-Forming Inverters: Mechanism, methods, and challenges

Over the past decades, because of boosted energy demands and the serious concerns of climate change, inverter-based resources (IBRs) have been widely deployed to integrate renewable energy into power systems for the goal of carbon neutrality. Thanks to the full controllability of power electronic devices, IBRs have the capability to implement reliable and flexible power regulation, which makes them technically feasible for enhancing the resilience and energy efficiency of power systems.
