According to joining the different disturbance, this method can be divided into active frequency drift with fixed disturbance method and active frequency drift with feedback method.
The results indicate that non-detection zone of active frequency drift with feedback method is obviously less than non-detection zone of active frequency drift with fixed disturbance method.
结果表明，带反馈的主动移频式孤岛检测的检测盲区明显小于固定扰动的主动移频式孤岛检测的检测盲区。

This paper proposed a novel active frequency drift with feedback based on single-phase single stage PV grid-connected generation system for the complexity of the control in traditional method.
