An Analysis of Unbalance Load Flow of Secondary Distribution System Based on Adaptive of GIS

This paper presents the power flow simulation on the virtual secondary distribution system as a PEA pattern via adaptive of GIS that is applied by the forward-backward sweep method for analyzing the weakness point of the voltage magnitude. The simulation results were presented by interacting on the power system topology network. Moreover, it can be used to pivot the objective information for convenience and rapid finding of the weakness of the grid. This simulation results were tested with the three phases unbalance power system of 85 nodes of PEA. Therefore, this tool can be used in simulation to serve as essential data for analysis that has presented several ways of analysis to deal with the problem and deployed by the other applications for the future.
