Challenges in DC Microgrids
Direct current (DC) microgrids are emerging as a promising solution for integrating renewable energy, battery storage, and electric vehicle infrastructure with high efficiency and reliability. However, the shift toward DC distribution introduces a new set of technical and operational challenges.
This presentation provides an accessible overview of the key issues facing DC microgrid development, including protection and fault detection, system stability, and safe interconnection with existing AC networks. Drawing from both research and industry experience, the talk explores how protection schemes, and standards are evolving to support the next generation of resilient, flexible, and efficient DC power systems.
Attendees will gain a broad understanding of the opportunities and barriers shaping DC microgrids today, and how these systems are poised to influence the future of power distribution.
