Microgrids interconnection to upstream AC grid using a

Actually, faults in the microgrid and upstream AC grids can damage grid apparatuses and its sensitive loads. In [11–15], fault current limiter (FCL) as a protection device in the microgrid is presented to limit the magnitude of the fault current. In [11], FCL is introduced as a solution for connecting upstream AC grid to the downstream microgrid.
