Abstract
This paper presents an investigation into the use of superconducting fault current limiters (SFCLs) for microgrid integration into distribution networks and their associated protection systems. SFCLs are investigated for their suitability to prevent loss of coordination between the main distribution network's fuse and recloser protection infrastructure when microgrid integration is present. Additionally, SFCLs are investigated for their suitability in aiding internal microgrid overcurrent protection by assessing their capability of use for bidirectional short circuit current flow. The evaluation is demonstrated through use of the EMTP-RV software with a typical distribution network and microgrid as a test bench.Keywords
