Rural distribution network reconfiguration with dispersed generation

The models of distribution network reconfiguration should consider radial topology in their formulation. So the paper presented radial constraints in a mathematical model for a distribution network Reconfiguration and gave a preliminary analysis of radial constraints. The mathematical model for distribution network reconfiguration problem was one in which the radial constraints were represented explicitly and showed that radial constraints can be considered in a simple and efficient way. The paper proposed the use of a branch - bound method and Primal-dual interior point method to solve power dispatch and optimization reconfiguration problem of a distribution power system. From the result of the case study, it can be seen from the 33 nodes radial distribution test system that DG has the effects of a loss reduction improvement over feeders in the case, and the distribution system without DG are different from those with DG.
