A novel islanding method based on the alternate current disturbances for photovoltaic grid-connected inverters

This When the power generated by the distributed power generation system matches with the consumed power of the local loads, and the load phase angle is equal to the angle of the current disturbance, even if the islanding occurs, the voltage frequency at the point of the common coupling (PCC) always keeps in non-detecting zone (NDZ). A detection method… CONTINUE READING
