Comparison of the proposed method.

Islanding detection method	Small/large power discrepancy during islanding accurately detected/total cases	Test-description balanced/unbalanced load joining during normal condition accurately detected/total cases	Balanced/unbalanced load separation during normal condition accurately detected/total cases	Speed (cycles)	Accuracy (%)	Computational burden
OVP/UVP	16/20	16/20	16/20	5 to 6	81.6	Low
Wavelet transform	17/20	17/20	18/20	1 to 2	88.3	High
