Intelligent islanding detection with grid topology adaptation and minimum non-detection zone

Electric Power Systems Research, 2020
Abstract Islanding is the condition in which a distributed generator (DG) continues to power an area even though the electrical grid power is no longer present. This can be extremely dangerous to utility workers, and many techniques are dedicated to detect such a situation.

Islanding Detection of Hybrid Distributed Generation Under Reduced Non-Detection Zone

IEEE Transactions on Smart Grid, 2018
Future distribution systems are faced with more challenges on islanding detection due to the increasing penetration level of inverter-based distributed generators (DGs). Different DG technologies, inverter control as well as other advanced inverter functions, such as fault ride through are challenging the capability of islanding detection schemes.
