The method is based on creating a perturbation in the system using positive feedback and d-q implementation algorithm. The conventional passive anti-islanding schemes fail to detect islanding during power balancing conditions, but the novel active anti-islanding controller ensures that the voltage (or frequency) at the point of common coupling (PCC) is automatically driven beyond the threshold preset values. This proposed scheme has been tested in the presence of non-linear loads and development has found faster islanding detection compared to the existing methods. Further, the islanding conditions are simulated and accurately verified on real time.falseanti-islanding | d-q implementation | distributed generation | non detection zone | positive feedback | solar PVConference Paper7 May 201597103797cpConference Proceeding7
