4. Need Of Microgrid Protection – In grid-connected mode, the fault currents of higher magnitudes (10–50 times the full load current) are available from the utility grid in order to activate conventional OC protection devices. On the contrary, for a stand-alone Micro- grid the fault current of about five times the full load current is available .
