Optimal Power Flow(OPF)plays a crucial role in optimization and operation of the bipolar DC distribution network(Bi-DCDN).However,existing OPF models encounter difficulties in the power optimization of Bi-DCDNs due to the optimal power expressed as a product form,i.e.,the product of voltage and current.Hence,this brief formulates the OPF problem of Bi-DCDNs using the branch flow model(BFM).The BFM employs power,instead of current,to account for the unique structure of Bi-DCDNs.Convex relaxation and linear approximation are sequentially applied to reformulate the BFM-based OPF,presenting it as a second-order cone programming(SOCP)problem.Further,the effectiveness of the proposed OPF model is verified in case studies.The numerical results demonstrate that the BFM-based OPF is a feasible and promising approach for Bi-DCDNs.
