The generation of offshore wind power is less predictable. This can cause the overload of offshore DC transmission system and thus requires the curtailment of wind power. To reduce the amount of wind power curtailment, a method of optimising DC power flow using DC power flow controller (DC‐PFC) is proposed. The analytical expression of coordinating DC‐PFCs and converters in controlling the power flow of the DC system has been created. Method has been developed to optimise the power flow of DC grids within which control setting changes automatically in different wind conditions to reduce both the power curtailment and power losses. The proposed method has been demonstrated and validated on a 9‐port DC system. It is concluded that both the curtailment of wind power and power losses are effectively reduced by inserting DC‐PFCs into DC grids.
