異なる能動的単独運転検出方式の太陽光発電インバータが混在連系した場合の実機検証

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.
