A Multistage Passive Islanding Detection Method for Synchronous-Based Distributed Generation

IEEE Transactions on Industrial Informatics, 2022
A multistage approach to passive islanding detection is proposed that utilizes a decision-tree-like classification algorithm. The novelty of the proposed method is centered on the way in which features are passed to subsequent stages of the decision tree (DT).

Superimposed Impedance-Based Passive Islanding Detection Scheme for DC Microgrids

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2022
Due to improved efficiency, reduced conversion stages, integration of distributed generators (DGs), and increased use of DC loads, DC microgrids (MGs) are earning extensive approval in modern power grids. Islanding detection is a critical issue for both AC and DC MGs. If the detection technique fails, it may lead to instability in the system, affecting

A passive islanding detection technique for distributed generations

2017 7th International Conference on Power Systems (ICPS), 2017
Passive islanding detection techniques based on the rate of change of voltage, phase angle and frequency perform well in case of large mismatch of power at the distributed generation terminalsduring islanding. However, such methods find limitation in detecting islanding conditions when power mismatch is very low.

Comparative assessment of passive islanding detection techniques for microgrid

2017 International Conference on Innovations in Information, Embedded and Communication Systems (ICIIECS), 2017
The increased requirement for clean, cost effective and uninterrupted electricity has led to the incorporation of microgrid including distributed generation (DG) units. One of the major issue with DG interconnection is islanding detection. This paper presents the comparative assessment report of islanding detection techniques on the basis of their non ...

A passive islanding detection method based on interharmonic impedance

2017 IEEE Conference on Energy Internet and Energy System Integration (EI2), 2017
In this paper, a passive islanding method based on PCC point interharmonic impedance measurement is proposed to solve the problem that the passive passive islanding detection method is too large to detect the dead zone. Which also overcomes the problem that the traditional impedance measurement method increases in the non-detection area (NDZ) when the ...

Enhanced Multi-Criteria-Based Passive Islanding Detection Scheme

International Review of Electrical Engineering (IREE), 2014
In 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.

Performance assessment of IMF-based passive islanding detection method in various islanding and non-islanding events

2015 IEEE Eindhoven PowerTech, 2015
This paper evaluates the performance of a passive islanding detection method in various islanding and non-islanding events and different network conditions. The method is based on calculating the intrinsic mode functions (IMFs) of the voltage of point of common coupling (PCC) using the empirical mode decomposition (EMD) technique.
