Methods to Detect the Occurrence of an Unintentional Island with Passive Approach: A Review
Journal of The Institution of Engineers (India): Series B, 2021Unintentional islanding is one of the serious concerns to be addressed when interfacing a distributed generation source, as it causes damage to the equipment and personnel. Many algorithms have been proposed for islanding detection in the literature which are classified into local methods (passive, active and hybrid), communication-based methods, and ...

A passive islanding detection index based on variation of signal energy
2012 3rd IEEE International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2012A new index for passive islanding detection is proposed. The approach exploits the inherent harmonic distortion produced by grid-connected power converters as well as the frequency dependent changes in the grid impedance as seen by the distributed generator before and following islanding.

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.

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 ...

Enhanced Multi-Criteria-Based Passive Islanding Detection Scheme
International Review of Electrical Engineering (IREE), 2014In this paper enhanced multi-criteria-based passive islanding detection scheme is presented. Multi-criteria based islanding detection is based on measuring the change of voltage unbalance and voltage total harmonic distortion of all phase-to-phase voltages which are also multiplied by voltage sequence components dependent value.
