DC Microgrid, Faults and Detection Techniques: A Comprehensive Review

The increasing integration of sources of renewable energy and the growing demand for reliable and efficient power system has led to a surge in interest in and the deployment of DC microgrids. DC microgrids offer numerous advantages, such as improved energy efficiency, enhanced integration of distributed energy resources (DERs), and reduced losses in contrast to their counterparts in AC. However, the unique characteristics of DC systems necessitate the development of specialized protection strategies to ensure these networks' reliable and secure operation. This paper provides an extensive overview of DC microgrid protection strategies, emphasizing the innovations and challenges in preserving the integrity and stability of these systems.
