Review of dc-dc converters for multi-terminal HVDC transmission networks (2016, background): “Recent consideration of offshore wind farms by many European countries with real possibilities of building offshore multi-terminal HVDC networks and inter-regional dc grids, has encouraged serious research and development effort from major HVDC manufacturers and academia [1, 8, 12, 43-45, 47-59].”
Impact of HVDC Transmission System Topology on Multiterminal DC Network Faults (2015, background): “Nevertheless, opening times of 2 ms are possible if several mechanical switches are connected in series, as in the modular hybrid IGBT dc breaker proposed by ABB [13].”
