A New Passive Islanding Detection Solution Based on Accumulated Phase Angle Drift
Applied Sciences, 2018 The existing passive methods for islanding detection are mainly based on the detection of voltage and frequency deviation after islanding, using protections such as voltage vector shift (VVS) and rate of change of frequency (ROCOF).

A passive communication based islanding detection technique for AC microgrid
International Journal of Electrical Power & Energy Systems, 2022 Abstract This paper presents a secured communication based passive anti-islanding technique, using phase angle difference information of superimposed impedance computed at both distributed generation (DG) and point of common coupling (PCC) ends. In the approach, the PCC end signal information is transmitted every cycle to DG sites to analyze the ...

Islanding Fault Detection in Microgrids—A Survey
Energies, 2020 This paper provides an overview of islanding fault detection in microgrids. Islanding fault is a condition in which the microgrid gets disconnected from the microgrid unintentionally due to any fault in the utility grid.
