Experimental Verification in Case of Mixed Connection in PV Inverters using Different Active Islanding Detection Methods

Abstract

It is essential that photovoltaic (PV) systems detect islanding quickly to ensure electrical safety. We have proposed and developed a new active islanding prevention method that detects harmonic impedance. To verify the effectiveness of the proposed method, we conducted performance evaluation tests in the case of a mixed connection in PV inverters through different active islanding detection methods.
