Improved Three-Phase AFD Islanding Detection Based on Digital Control and Non-Detection Zone Elimination [PDF]
Energies, 2018 This paper proposes an improved active frequency drift (AFD) islanding detection method of a three-phase inverter. Different than the existing single-phase AFD method, in the three-phase system, the disturbance is added to the phase angle, which takes ...

A Novel Islanding Detection Scheme without Non Detection Zone
The Transactions of the Korean Institute of Power Electronics, 2015 Unintentional islanding results in safety hazards, reliability, and many other issues. Therefore, the islanding detection of a power conditioning system of a distributed generation, such as a grid-connected photovoltaic inverter, is a key function for standard compliance.

A simple technique for islanding detection with negligible non-detection zone [PDF]
2009 IEEE Power & Energy Society General Meeting, 2009 Although active islanding detection techniques have smaller nondetection zones than passive techniques, active methods could degrade the system power quality and are not as simple and easy to implement as passive methods. The islanding detection strategy, proposed in this paper, combines the advantages of both active and passive islanding detection ...

IEEE Transactions on Smart Grid, 2021 This article proposes a fast and reliable two-level islanding detection method (IDM) for grid-connected photovoltaic system (GCPVS)-based microgrid. In the first level of the proposed IDM, the magnitude of the rate of change of output voltage (ROCOV) is computed.
