Islanding detection in microgrids

2013 IEEE Power & Energy Society General Meeting, 2013
The idea of reshaping existing centralized electricity networks to decentralized small scale local power networks namely micro-grids, operating whether autonomous or interconnected to main distribution grid, became an important discussion. Islanding of a generator inside the micro-grid can cause problems in operation and management of the network ...

Detecting genomic islands using bioinformatics approaches

Nature Reviews Microbiology, 2010
Bacterial genomes contain clusters of genes that are acquired by horizontal transfer, called genomic islands (GIs). GIs are frequently associated with microbial adaptations that are of medical and environmental interest, and they have had a substantial impact on bacterial evolution. Therefore, there is growing interest in efficiently identifying GIs in

Islanding detection and connection requirements

2007 IEEE Power Engineering Society General Meeting, 2007
This paper reflects how anti-islanding protection has developed with increasing DG penetration. Starting from a local issue it has developed to possibly affect system security. The focus here is on how islanding detection methods and anti-islanding protection settings relate to distribution level and TSO requirements.

Islanding detection in smart grids

2010 IEEE Energy Conversion Congress and Exposition, 2010
All distributed generators (DG), especially those connected to low voltage distribution grids are required to detect islanding conditions. The methods for detecting islanding are classified in three main categories: passive, active and communication based.

Islanding detection in DC network

2017 52nd International Universities Power Engineering Conference (UPEC), 2017
Nowadays, the expansion of renewable energies (the wind, solar, ocean wave, fuelcell-some of them are natively DC) in power system as a potential solution for the environmental protection and lack of energy when the traditional energies are going to be exhausted.

Synchrophasor-based anti-islanding detection

2013 IEEE Grenoble Conference, 2013
During a loss-of-main or islanding situation, distributed generation units remain feeding a part of the electrical system without connection to the main power system. Although many islanding detection methods have been proposed in literature, and some of them are being used, there is currently no islanding detection technique that meets utilities ...

Unintentional islanding detection in microgrid

2017 International Conference on Energy, Communication, Data Analytics and Soft Computing (ICECDS), 2017
With the growing demand of electricity, conventional generation is no longer the most efficient method. This brings the concept of distributed generation in the picture, in which there are generation sources at load end. This type of structure is called microgrid. The concept of microgrid is still under development.

Hybrid ROCOF Relay for Islanding Detection

Journal of Electrical Engineering & Technology, 2021
Distributed generation (DG) is increasing in day to day life to meet the global energy consumption demand. One of the major problems with such DG is islanding. The islanding is caused in the grid connected system when a part of DG is disconnected from the main grid and continues to feed the load connected.

Islanding detection in distributed generation

2016 International Conference on Circuit, Power and Computing Technologies (ICCPCT), 2016
In the present times, distributed generation has acquired lots of importance in the power industry. The consequences on the power system develop further significance with the increase in the contribution of distribution energy resources to the electric power production.

Islanding and Non-Islanding Detection for Grid Connected Distribution System

Applied Mechanics and Materials, 2014
In this paper, wavelet transform based approach is proposed for islanding detection in a distribution system. The negative sequence voltage and negative sequence current obtained due to disturbances are measured at the point of common coupling (PCC) and given to the wavelet processing module to extract features like standard deviation and energy ...
