DC Microgrid Protection

open access: yesProceedings 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

Protection of Microgrids

open access: yes, 2021
The concept of microgrids goes back to the early years of the electricity industry although the systems then were not formally called microgrids. Today, two types of microgrids can be seen: independent and grid connected. The protection requirement of these two types differs as the protection needs of an independent microgrid are intended for ...
