TLDR
A new frequency-shift anti-islanding protection method using a twin-peak band-pass filter for grid-interconnected photovoltaic (PV) power systems that works perfectly for various kinds of loads such as resistance, inductive and capacitive loads connected to the PV system.Abstract:
The authors have successfully developed and industrialized a new frequency-shift anti-islanding protection method using a twin-peak band-pass filter (BPF) for grid-interconnected photovoltaic (PV) power systems. In this method, the power conditioner has a twin-peak BPF in a current feedback loop in place of the normal BPF. This new method works perfectly for various kinds of loads such as resistance, inductive and capacitive loads connected to the PV system. Furthermore, because there are no mis-detections, the system enables the most effective generation of electric energy from solar cells. A power conditioner equipped with this protection was officially certified as suitable for grid-interconnection.read more

Study and Development of Anti-Islanding Control for Grid-Connected Inverters
TL;DR: In this paper, the authors propose a new family of anti-islanding schemes that meet IEEE 1547 interconnection standards, that can detect all disruptions in service, have minimum power-quality impact, require low-cost implementation, work for multiple distributed generators, and work for any multi-phase inverters.

Prevention of islanding in grid‐connected photovoltaic systems
TL;DR: It is concluded that no ‘perfect’ islanding prevention method yet exists, but also that many existing methods or combinations thereof work very well in practical situations and an investigation of what constitutes ‘sufficient’ Islanding prevention is needed.
