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.

An Integrated Framework for Sensing Radio Frequency Spectrum Attacks on Medical Delivery Drones

, 2020
Drone susceptibility to jamming or spoofing attacks of GPS, RF, Wi-Fi, and operator signals presents a danger to future medical delivery systems. A detection framework capable of sensing attacks on drones could provide the capability for active responses.

Fermi Large Area Telescope View of the Core of the Radio Galaxy Centaurus A [PDF]

, 2010
We present gamma-ray observations with the LAT on board the Fermi Gamma-Ray Telescope of the nearby radio galaxy Centaurus~A. The previous EGRET detection is confirmed, and the localization is improved using data from the first 10 months of Fermi science

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 ...

An Effective Index for Islanding Detection Based on Fast Discrete S-Transform

Advances in Electrical and Electronic Engineering, 2019
Passive methods of islanding detection have the advantage of not perturbing the system, but they suffer from large Non-Detection Zone (NDZ) and unpredictable detection time. In this paper, a new passive scheme for islanding detection, based on estimating

Solar-like oscillations in massive main-sequence stars. I. Asteroseismic signatures of the driving and damping regions [PDF]

, 2009
Motivated by the recent detection of stochastically excited modes in the massive star V1449 Aql (Belkacem et al., 2009b), already known to be a $\beta$ Cephei, we theoretically investigate the driving by turbulent convection.

An innovative hybrid method for islanding detection using fuzzy classifier for different circumstances including NDZ

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 ...
