Improved Active Islanding Detection Technique with Different Current Injection Waveform [PDF]

open access: goldProcesses, 2023
The active frequency drift (AFD) method is an effective method to detect islanding in grid-connected photovoltaic systems. However, it has some inherent drawbacks, such as generating higher harmonics. In order to reduce the harmonics and non-detection zone (NDZ), various improved AFD methods have been proposed, but they still suffer from high harmonics
