Abstract: A new efficient two-stage load flow method for meshed distribution networks is presented in this paper. First, a forward/backward sweep load flow method for radial distribution networks is reviewed. Based on the multi-port compensation theory, a two-stage method is then put forward to solve the load flow problem of meshed distribution networks. In the first stage, a meshed network is converted to a radial network by breaking the loops. The load flow of this radial network is calculated by applying the forward/backward sweep method. Breakpoint currents are worked out. In the second stage, injection currents of breakpoints are modified and the load flow of the radial network is calculated again, which is just the load flow of the original meshed network. Two example networks are employed to demonstrate the efficiency of the proposed method. Results are also given and compared with another method.
