The insertion of DC power‐flow controller (DC‐PFC) in the DC grid can increase the control dimension of the DC current and improve the active power distribution and coordination control of DC grid. In this study, the combined application of DC‐PFC for multi‐terminal HVDC system has been proposed. Based on the analysis of existing DC‐PFC, it shows that the two combined application structures of DC‐PFCs can achieve multi‐objective power‐flow control and increase the control dimension with greater flexibility. Also, a composite DC‐PFC is proposed to obtain the completely decoupled power‐flow control. A simulation mode is built to test the feasibility and effectiveness of the proposed composite DC‐PFC.
