The present work proposes an islanding identification scheme based on the discriminating factor of islanding (DFI) extracted by the superimposed angle of impedance. The suggested methodology effectively identifies islanding within half of the cycle, discriminates islanding events (IEs) from non-islanding events (NIEs) at 0% power mismatch (PM), and unnecessary tripping due to different forms of NIEs. A significant figure of IEs and NIEs have been tested across a wide assortment of PM on 7 bus microgrid test systems. Within this work, three separate cases (I, II, and III) are addressed. In the last, the results that were obtained from the proposed methodology is compared.
