Islanding detection in three-phase and single-phase systems using pulsating high-frequency signal injection [PDF]
, 2015 This paper analyzes the use of pulsating high-frequency signal injection for islanding detection purposes. Active islanding detection using high-frequency signal injection is an appealing option due to its reduced nondetection zone, reduced cost, and ...

Islanding Detection Using a Micro-Synchrophasor for Distribution Systems with Distributed Generation
Energies, 2020 Distributed Generation (DG) has changed the power generation system to small-scale instead of large-scale generation. The demanding issue with the interconnection of DG is the detection of unintended islanding in a network.

Islanding detection method based on a Thevenin‐like model
IET Generation, Transmission & Distribution, 2015 Reliable detection of islanded operation is essential in distribution systems with large penetration of the distributed generation. Commonly‐used protections present performance limitations in terms of sensitivity and stability. To overcome such limitations, this study proposes to enrich classical protections by adding a passive islanding detector ...

Islanding detection method for microgrids based on CatBoost
Frontiers in Energy Research, 2023 The occurrence of unintentional islanding will seriously threaten the stable operation of a microgrid (MG). Therefore, detecting the islanding of an microgrid timely is an important premise to ensure the microgrid operates safely and stably. However, the problem of dead zone exists in the traditional islanding detection process because the threshold of

Coordinated operation of parallel-connected inverters for active islanding detection using high frequency signal injection [PDF]
, 2013 The high frequency impedance measured at the terminals of inverters connected in a microgrid by means of the injection of a small magnitude, high frequency voltage, has been shown to be a reliable metric to detect islanding.
