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

Protection of converter dominated MV microgrid using changes in current's phase angle
IET Generation, Transmission & Distribution, 2022 Converter interfaced distributed generations in a microgrid feed the modulated current of limited magnitude during fault conditions. The protection design and its operation are thus challenging due to limited fault current which is further reduced by ...
