“…Power mismatches between source and load during islanding conditions lead to harmonic distortions that are calculated by THD. It is a signal‐harmonic distortion measurement strategy being specified as the proportion of the total harmonic component and the basic frequency and typically a percentage value 70 . If the parameter being monitored and surpasses the set limit value, the DG must be disconnected from the inverter 71 .…”

Summary Renewable sources of energy are used extensively in the distribution grid to meet the need for growing electricity demand and to resolve the global heating crisis caused by traditional energy sources. They offer many advantages like better efficiency, power quality, and lower air pollution. One of the vital issues with these integrations is islanding condition arising due to the sudden disconnection of grid because of some abnormal situations; however, the distributed generation (DG) retains the power supply to the local loads. Thus, efficient detection of islanding and quick detachment of DG are vital to prevent failure of equipments, grid safety disruption, and risks to personnel safety. In this context, this article represents a comprehensive review of islanding issues and different islanding detection methods (IDMs) that provide a detailed assessment for filling the research gap and thereby highlights the various issues related to island detection. A broad classification of IDMs is established based on the conventional and modern techniques such as local (Active, Passive & Hybrid) and remote IDMs with their detailed illustrations including both intelligent and signal processing‐based IDMs. Comparison of various IDMs based on their merits, demerits, and various performance analysis including the non‐detection zone, detection time, quality factor, power quality, effect on a microgrid, implementation cost, and applicability in multi‐DG system is provided. Hence, this review will provide an insight for the new researchers interested in the area highlighting the different islanding detection techniques with their relative merits and demerits.

“…Passive methods include any system that attempts to detect transient changes on the grid, and then uses that information as the basis to determine a probable failure of the grid or a temporary change . Under voltage/over voltage (UV/OV) , rate of change of frequency (ROCOF) , vector surge relay technique (VS) , under frequency/over frequency (UF/OF) , voltage phase jump (VPJ) , voltage harmonic distortion , and total harmonic distortion (THD) are a few examples of passive islanding detection techniques. In the case of correct operation of the protective relay, the relay should be set by considering upper and lower threshold values.…”

In this paper, islanding detection in the presence of different technologies of distributed generations (DGs) is discussed. Three types of DGs, namely a synchronous generator (SG), a wind energy conversion system (WECS), and a photovoltaic (PV) system, with distribution network parameters as well as linear and nonlinear loads are simulated using the Power System Computer Aided Design/Electromagnetic Transients Including DC (PSCAD/EMTDC) software. To detect the island state, a comprehensive islanding detection algorithm based on wavelet transform (WT) and rate of change of frequency (ROCOF) relay method is considered. To determine the islanding threshold value, the voltage and frequency values of sensitive buses are sampled at regular intervals, and the signals are analyzed with WT using MATLAB. The proposed algorithm could detect the exact island state definitively with the consideration of various disturbance signals such as capacitor bank switching, induction motor switching, and the sudden disconnection of power sources and loads from different buses of the distribution network. The results of the simulation are validated with the logic of ROCOF relay islanding detection method, which determines the accuracy threshold value when the power generation and load consumption difference is negligible. In addition, the proposed algorithm based on the rested DG's output power in the islanding state can supply prioritized loads based on thier importance.

Jing et al [35] proposed islanding detection scheme based on the positive feedback of voltage harmonics distortion. Later on, Samui et al [36] proposed wavelet singular entropy based islanding detection technique for lower power mis matches.…”
