Joint Working Group C6/B4.37 - Medium Voltage DC Distribution Systems

Tue, Oct 18, 2022 1:00 PM - 2:30 PM CEST

Power Electronics is a critical enabler for an accelerated transition to achieve a net-zero carbon electricity network. Such a technology provides controlled power flow as DC couplers, point-to-point connections as DC links and meshed DC grids with multiple points of connection. Medium-voltage DC (MVDC) can be viewed as acting in the same way as high-voltage DC (HVDC) systems in transmission grids, just on a smaller scale and over comparatively shorter distances or at a specific site. This joint working group (JWG) C6/B4.37 has built upon and leveraged the expertise and knowledge from different Study Committees to present the potential advantages of a DC approach (MVDC networks incorporating DER) as an alternative to AC distribution systems. As the first of its kind, this Technical Brochure (TB) summarized the latest industrial practices and engineering insight, academic interests and research advancement on Medium Voltage DC (MVDC) system at the international level. It will contribute to the accelerating of a $multi billion market, as part of the net zero energy transition
