Abstract Integrated with the characteristics of the back/forward sweep, this paper presents the various models of distributed generators (DGs) adapted to the back/forward sweep method. Considering the limits of the back/forward sweep for solving PV node and meshed network, their power correction equations are put up based on resistance matrix, reactance matrix and mismatch of voltage magnitude, planning the flexible nodal numbering scheme suited for DGs and meshed network, giving the procedure of the improved back/forward sweep algorithm．Plenty of simulations with 20 buses and IEEE 90 buses system are carried out to illustrate the performance of the proposed method. The results show that the presented method is simple, flexible, reliable and available to solve power flow of radial and meshed distribution network with multi-source and multi-type DGs.

Key words： Distributed generation power flow calculation back/forward sweep meshed network power correction distribution network.
