Comparative Evaluation of Multiport DC Power Router for DC Distribution Grid
2020 IEEE 9th International Power Electronics and Motion Control Conference (IPEMC2020-ECCE Asia), 2020DC power router serves as the key node in DC distribution grid, with the multiple operation aims of voltage regulation, power dispatching and fault protection. In this paper, three series of DC power router topologies have been developed in duality of classical AC substation, including AC-bus type, DC-bus type and DC-fault-tolerant (DC-FT) type.

Power flow control devices in DC grids
2012 IEEE Power and Energy Society General Meeting, 2012A HVDC grid based on voltage source converters (VSC) is an attractive solution for the grid-integration of offshore renewable energy, interconnection of AC grids, facilitation of power markets, and energy emergency support. However, the power flow within the DC grids is determined by the line resistance, and cannot be fully controlled by the VSCs only.
