Spectral Kurtosis-Based Island Detection Technique
2021The increasing rate of energy demand in the recent times is unprecedented and it is driving the increasing demand of renewable distributed generations in distribution system on a large scale. This significantly brings uncertainty to grid operation. Inadvertent islanding of microgrid is a major issue in today’s smart distribution grid.

2018 IEEE 7th World Conference on Photovoltaic Energy Conversion (WCPEC) (A Joint Conference of 45th IEEE PVSC, 28th PVSEC & 34th EU PVSEC), 2018
This paper describes and explores the effectiveness of a novel power line carrier-based islanding detection and prevention system in which a dynamic voltage restorer (DVR) is usedto transmit a low-frequency power line carrier permissive (PLCP) signal. The approach itself is briefly described, and then results are provided showing the effectiveness of ...

Neuro-wavelet based islanding detection technique
2010 IEEE Electrical Power & Energy Conference, 2010Connecting distributed generators to the normal radial distribution system improve the power quality and increase the capacity of the electric grid. However, they disturb the radial nature of the network and thus give rise to many problems. Unintentional islanding is one of the encountered problems.

Smart grid opportunities in islanding detection
2013 IEEE Power & Energy Society General Meeting, 2013The performance of many existing islanding detection methods for cases with multiple distributed generators within a single island is either inadequate or unknown. The deployment of Smart Grid technologies offers opportunities for improving the islanding detection of a circuit.

Islanding detection using decision tree approach
2010 Joint International Conference on Power Electronics, Drives and Energy Systems & 2010 Power India, 2010Islanding occurs when part of a distribution network is disconnected from the rest of the power system but continues to be energized by a distributed resource (DR). Failure to trip the islanded DR can lead to serious problems for this DR and the connected loads.

Satellite Detection of Urban Heat Islands
Monthly Weather Review, 1978Abstract On 28 July 1977 an unusually cloud-ftee nighttime thermal infrared image of the midwestern and northeastern United States from the NOAA 5 satellite enabled detection of more than 50 urban beat islands. Analysis of digital data from the satellite for selected cities yielded maximum urban-rural temperature differences ranging from 2.6 to 6.5°C ...

Detection of Islanding for Microgrid Based on Discrimination Factor of Islanding
2020 21st National Power Systems Conference (NPSC), 2020The present work proposes an islanding identification scheme based on the discriminating factor of islanding (DFI) extracted by the superimposed angle of impedance. The suggested methodology effectively identifies islanding within half of the cycle, discriminates islanding events (IEs) from non-islanding events (NIEs) at 0% power mismatch (PM), and ...

Active ROCOF Relay for Islanding Detection
IEEE Transactions on Power Delivery, 2017Intentional frequency perturbation by recently researched active islanding detection techniques for inverter based distributed generation (DG) define new threshold settings for the frequency relays. This innovation has enabled the modern frequency relays to operate inside the non-detection zone (NDZ) of the conventional frequency relays.

Islanding detection for distributed generation system
2016 IEEE 1st International Conference on Power Electronics, Intelligent Control and Energy Systems (ICPEICES), 2016Distributed generator (DG) is widely used to fulfil additional power requirement and to improve the performance of the system. Distributed generator gives reliable and qualitative power. Islanding is a challenge for DG. It must detect islanding as soon as possible.
