Proceedings of the 4th International Conference on Information Management & Machine Intelligence, 2022 DC microgrids have gained increasing attention over the decades. Compared to AC micro grids, they have higher power delivery ability, higher efficiency, and fewer control levels. Although DC microgrid has better performance in many areas, they still face a significant challenge in protection. That is due to the feature of DC fault with no zero-crossing

Adaptive distance protection for microgrids [PDF]
IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015 Due to the increasing penetration of distributed generation resources, more and more microgrids can be found in distribution systems. This paper proposes a phasor measurement unit based distance protection strategy for microgrids in distribution system. At the same time, transfer tripping scheme is adopted to accelerate the tripping speed of the relays
