A Passive Islanding Detection Technique for Grid-Connected Photovoltaic Inverters
2018 IEEE International Students' Conference on Electrical, Electronics and Computer Science (SCEECS), 2018One of the problem associated with grid connected distribution generator is islanding, which occurs when a disconnected distribution generator is energized unintentionally. If islanding is not detected quickly it could pose a serious threat to the distribution generator and to the personnel working.

Modeling, control and islanding detection of microgrids with passive loads
Proceedings of 14th International Power Electronics and Motion Control Conference EPE-PEMC 2010, 2010This paper presents a control scheme for microgrids with passive loads. The existing control techniques for distributed generation systems are designed to operate either in the grid-connected or in the islanded mode. In the grid-connected mode of operation, a current-controlled scheme based on d-q variables is used for the regulation of real and ...

A new impedance-based approach for passive islanding detection scheme
2013 4th IEEE International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2013This paper presents a new approach for islanding detection that is based on monitoring measures of impedance at the point of common coupling (PCC). A frequency dependent model that characterizes the change in circuit topology when an island occurs is developed as a first step in systematically selecting impedance metrics and thresholds for islanding ...

Principal component based passive islanding detection technique for distributed generations
2016 21st Century Energy Needs - Materials, Systems and Applications (ICTFCEN), 2016This paper presents a new technique for islanding detection using the phase angle between positive-sequence voltage and current signals. In order to discriminate between islanding and non-islanding situations, the phase angle derived at the rotating machine or inverter-based distributed generation terminal is used an input feature vector for the ...

Comparative Assessment of Passive Islanding Detection Techniques for Distributed Generations
2019In this paper, a comparative study of the available important passive islanding techniques used for distributed generation is carried out. The following passive methods are compared and analyzed: under/over voltage, under/over frequency, rate of change of frequency, voltage unbalance and total harmonic distortion, rate of change of active and reactive ...

Grid code compatible islanding detection schemes using traditional passive methods
13th International Conference on Development in Power System Protection 2016 (DPSP), 2016The focus in this paper is on development of voltage vector shift (VVS) based passive islanding detection as a part of grid code compatible combined islanding detection scheme or alone as a back-up for combined scheme. Islanding detection during utility grid frequency fluctuations could be made more reliable and also non-detection zone (NDZ) could be ...
