A reconfiguration analysis tool for distribution networks using Fast Decoupled power flow

This work proposes a tool for distribution network analysis focused on grid reconfiguration using the Fast Decoupled Newton-Raphson power flow method. The methodology uses the information of the network switching equipment status, without the need of a previous topological processing. The complex normalization approach was used to make viable the load flow calculation by the fast decoupled approach when applied to networks presenting lines with high R/X ratio, which is typical in distribution systems.
