“…Two famous ones are Sandia Frequency Shift (SFS) and Slip-Mode Frequency Shift (SMS), which belong to frequency shift methods and have been the classic active islanding detection methods up to the present day [1]- [6]. In addition, [7] and [8] proposed two methods based on the relationships between reactive power and frequency; [9] and [10] added a reactive power perturbation on the basis of SMS and SFS; [11] proposed a method based on a relationship between active power and voltage; [12] proposed the concept of perturbing reactive current, and [13]- [15] realized and tested it. Although new methods are constantly emerging, SFS and SMS are still being widely used.…”

“…The output currents of the inverter are controlled as a sinusoidal function of the frequency deviation of the voltage at PCC with respect to the network frequency before islanding. Thus, the inverter output currents can be expressed as in (6) [6]. (6) in which fvk-1 is the frequency of voltage at PCC in the previous cycle and θSMS is the phase angle shift for SMS method.…”

Abstract-This paper proposes a novel hybrid approach for islanding detection of inverter-based distributed generations (DG) based on combination of the Slip mode frequency-shift (SMS) as an active and rate of change of frequency (ROCOF) relay and over/under frequency relay as passive methods. This approach is utilized to force the DG to lose its stable operation and drift the frequency out of the allowed range of the frequency threshold. Performance of the proposed approach is evaluated under the IEEE 1547, UL 1741 and multiple-DG operation. The simulation results demonstrate the effectiveness of the proposed approach for detection of islanding, especially for loads with high quality factor. It operates accurately under the condition of load switching and does not interfere with the power system operation during normal condition. In other words, not only it holds the benefits of both SMS and ROCOF, but also it removes their drawbacks by having less non-detection zone and faster response.Index Terms-Constant-current controller, distributed generation (DG), islanding detection, Slip mode frequency-shift (SMS), rate of change of frequency (ROCOF) relay, inverter.

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.
