DC Microgrid Protection [PDF]

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
