Optimal coordination of overcurrent relays for microgrid operation using JAYA algorithm
e-Prime: Advances in Electrical Engineering, Electronics and EnergyIn modern microgrids, relay coordination is a very tedious task because of the variation in magnitude and direction of fault current. The change in fault current is diverse for inverter interfaced DGs (IIDGs) and synchronous-based DGs (SBDGs) The ...
