Power flow calculation for radial distribution systems with distributed generation

Through the analysis of wind turbines, photovoltaic systems, fuel cells and high frequency micro turbines, their models in power flow calculation were established in this paper. Moreover, a novel power flow algorithm based on back/forward sweep technology for radial distribution networks considering Distributed Generation (DG) is proposed. The algorithm develops a reactive power compensation method applying reactance matrix to handle all PV nodes in power flow studies (PFSs). A 33 bus test system is used to validate the proposed method. The simulation results show that the method is feasible and effective. Finally, the impact of DGs on voltage profile is analyzed using this method.
