| Abstract |
This paper examines the emerging field of Medium Voltage Direct Current (MVDC) systems, focusing on technological trends and electrical safety. As renewable energy integration and DC load proliferation reshape the electrical landscape, MVDC systems are becoming increasingly important. The study reviews global MVDC developments and addresses critical safety aspects unique to medium voltage DC power. Key technologies discussed include standardized network design, DC-DC converter safety, Common Mode Voltage/Current mitigation, grounding systems, protection coordination, and insulation monitoring. The report also explores comprehensive monitoring and diagnostic technologies for DC systems. Market outlook, regulatory landscape, and standardization efforts in the MVDC domain are examined. The study concludes by emphasizing the need for collaborative R&D, tailored safety standards, and the potential for MVDC to enhance grid flexibility and efficiency. |
