“…In order to prevent islanding, a lot of anti-islanding methods have been studied [4,5,6,7,8,9]. Among them, passive methods depends on the voltage monitoring only at point of common coupling to detect islanding [4,5], while active methods inject active signals intentionally in the PV inverter output to detect islanding [6,7,8,9].…”

“…Among them, passive methods depends on the voltage monitoring only at point of common coupling to detect islanding [4,5], while active methods inject active signals intentionally in the PV inverter output to detect islanding [6,7,8,9]. Since passive methods couldn't detect islanding when PV power and local load power are matched, active methods are essential for PV to detect islanding [9].…”

“…Recently, PV system using micro-inverters are widely disseminated in the field. Accordingly, an islanding issue for multiple PV micro-inverter systems has been paid attention due to their interaction not to detect islanding, even though the single micro-inverter unit can prevent islanding when the single unit is only tested [9]. This paper presents an improved active frequency drift (AFD) anti-islanding method for multiple single phase PV micro-inverter systems.…”

Islanding phenomenon of Photovoltaic (PV) system should be prevented because it causes a safety problem to utility service personnel and power supply facilities. Until now, various antiislanding methods have been proposed. However, these are mostly focus on the islanding prevention method for single PV system. Recently, PV system using micro-inverters are widely disseminated in the field. Accordingly, an islanding issue for multiple PV microinverter systems has been paid attention due to their interaction not to detect islanding, even though the single micro-inverter unit can prevent islanding when the single unit is only tested. This paper presents an improved active frequency drift (AFD) anti-islanding method for multiple PV micro-inverter systems. The proposed method injects every half-line cycle asymmetrical signals and uses the correlation between the injected asymmetrical signal and the corresponding half line cycle. The proposed method is verified by using PSIM simulation, compared with the conventional AFD method. It shows that the proposed method is highly effective to detect islanding even under multiple micro-inverter system while the conventional one doesn't detect islanding.

“…929, 2000 mentioned islanding condition, voltage will sudden variation when islanding condition is happen [2]. Comparison is measured voltage at PCC point (V PCC ) if V PCC > 110% or V PCC < 88% shown that islanding condition occurs [6]. Usually Nondetection Zone (NDZ) of islanding detection techniques is difficult evaluation but some techniques have effort such phase jump [7], active frequency drift (AFD) [8] and Sandia frequency shift (SFS) [9].…”

Abstract-The objective of this paper is to investigate relationship between voltage and nondetection zone of OUV/OUF of local islanding detection techniques of distributed generation in electric power system network. This paper shows experimental results of inverter-based DG and synchronous-based DG with parallel RLC load that causes the most difficulty in detection. The experiments have shown that, case of inverter-based DG: variation of active power associated with variation of off-grid voltage at V PCC , case of synchronous-based DG: variation of off-grid voltage at V PCC was not associate with variation of active power but variation of off-grid voltage at V PCC associated with variation of reactive power. Nondetection zone of OUV of synchronous-based DG are very possibility that Q can more than -9.6 MVAR or Q can less than 3.6 MVAR which they can affect the V PCC to outside of normal voltage range when islanding condition is happen.
