Comparisons between the three-phase current injection method and the forward/backward sweep method

This paper presents comparisons of two power flow methodologies for distribution system analysis: the three-phase current injection method – TCIM and the forward/backward sweep – FBS. These techniques were applied for large scale three-phase distribution systems, the advantages and drawbacks are emphasized and their computational performances are presented. The results presented in this work can be helpful to decide which one of the tested methods is the most suitable to solve a particular electrical system.
