A distribution feeder reconfiguration method has been developed. Feeder reconfiguration is an easy and in-expensive method, for distribution system loss reduction, which is done by maneuver in the network. In this work, Graph Theory approach has been adopted for analysis and optimization of distribution system. Distribution system partitioning and optimization is modeled as a linear programming problem, using this theory. The distribution system is modeled as a hyper-graph, and specific weights are assigned to every branch of the hyper-graph. Then the distribution system is partitioned to sub-graphs. Feeder reconfiguration for loss reduction can be performed in all of the sub-graphs, simultaneously. The most important feature of the presented method, is improving the performance of reconfiguration for large scale networks. Noticeable reduction in calculation time is the other advantage of network partitioning that makes it suitable for fast and real-time applications. Performance of the method has been presented on a standard distribution system. Solution algorithm and discussion is included.
