A Cascaded Converter Interfacing Long-Distance HVdc and Back-to-Back HVdc Systems [PDF]
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020 This paper proposes a cascaded converter dedicated to long-distance HVDC infeed and asynchronous back-to-back interconnection of receiving grids. The cascaded converter is consisted of MMCs in series and parallel connection, meeting the high DC voltage and power demand of HVDC system. It realizes hierarchical feeding and asynchronous interconnection of
