Distribution networks are usually multiphase and radial. To facilitate power flow computation and optimization and improve computational efficiency,a linear approximation of the power flow equation was proposed based on the radial distribution network. This equation can be easily used for the problems to reconstruct the distribution network reconfiguration,as well as restoration and optimal power flow. Case studies of the IEEE 13,34,37,123 node test feeders show the effectiveness and exactness of the proposed method.
