Adaptive Protection Coordination Method Design of Remote Microgrid for Three-Phase Short Circuit Fault

Energies, 2021
Generally, the fault current supplied by inverter-based renewable energy sources (IBRES) and electrical storage systems (ESS) is about 1.2 to 2 times their rated current and much lower than synchronous generators because the former acts as a current ...
