Medium Voltage DC Distribution Systems

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…
