A Novel Interline DC Power-Flow Controller (IDCPFC) for Meshed HVDC Grids

Power-flow control ability of meshed high-voltage direct-current grids can be improved by inserting a dc power-flow controller into the grids. Based on the study of existing dc power-flow controllers, this paper proposes a novel interline dc power-flow controller (IDCPFC) which has the benefit of fewer active switching devices, simpler control, little side effect on meshed grids, no external power source needed, and wide application occasions. The performance of the IDCPFC is validated by simulation and experimental tests. The results show that the proposed IDCPFC can achieve stable power-flow control in different conditions.
