Islanding Detection with Reduced Non-Detection Zones and Restoration by Reconfiguration
Energies, 2023 The development and use of PV (Photovoltaic), Wind, and Hydro-based Distributed Generation (DG) is presently on the rise worldwide for improving stability and reliability, and reducing the power loss in the distribution system with reduced emission of harmful gases.

Unintentional Passive Islanding Detection and Prevention Method with Reduced Non-Detection Zones
Energies, 2022 Islanding detection and prevention are involved in tandem with the rise of large- and small-scale distribution grids. To detect islanded buses, either the voltage or the frequency variation has been considered in the literature. A modified passive islanding detection strategy that coordinates the V-F (voltage–frequency) index was developed to reduce ...

An Intelligent Deep Convolutional Neural Networks-Based Islanding Detection for Multi-DG Systems
IEEE Access, 2022 Unintentional islanding is a problem in electrical distribution networks; it happens when the central utility is unintentionally separated from the rest of the distributed power system.

Journal of Radiation Research and Applied Sciences, 2022 Distributed energy resources (DERs) are an alternative to conventional fossil fuel-based energy resources for a pollution-free operation. But the integration of these DERs to the main grid comes with certain challenges, out of which unintentional ...

Islanding detection scheme for converter‐based DGs with nearly zero non‐detectable zone [PDF]
IET Generation, Transmission & Distribution, 2019 This study presents a new method for detecting an islanding event in a microgrid with embedded converter‐based distributed generation (DG). Unlike other schemes, the proposed scheme injects negligible perturbations into the microgrid after the generation of an alert signal.

Detection/estimation of the modulus of a vector. Application to point source detection in polarization data [PDF]
, 2009 Given a set of images, whose pixel values can be considered as the components of a vector, it is interesting to estimate the modulus of such a vector in some localised areas corresponding to a compact signal.
