Flexible Control of Power Flow in Multiterminal DC Grids Using DC–DC Converter [PDF]
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2016 This paper proposes an efficient control framework that utilizes dc-dc converters to achieve flexible power flow control in multiterminal dc (MTDC) grids. The dc-dc converter employed in this paper is connected in cascade with the dc transmission line, and is therefore named cascaded power flow controller (CPFC).
