Short-Circuit Analysis of DER-Based Microgrids in Connected and Islanded Modes of Operation

Energies, 2021
Since microgrids should be able to smoothly operate in two distinct modes—grid-connected and islanded, their fault currents can widely fluctuate depending on the operational mode. When the microgrid is connected to the grid, the highest fault current, by
