Network reconfiguration is not only an important method in circulate and control of distribution system, but also an important part of distribution management system. In theory, network reconfiguration is a complex and multi-object combination optimization problem. From 1980s, people have extensively studied on network reconfiguration of distribution system.Many relatively mature methods and theories of network reconfiguration have formed and developed.Distribution power flow calculation is the base of distribution network analysis. Some effective algorithms that have appeared recently in distribution power flow calculation are discussed in this paper, and the parts of them are modified. For example, weakly meshed distribution network and PV nodes are dealed with in the same way in back/forward sweep method.On the base of genetic algorithm, mimum of feeder looses, and the operation of simulated annealing, network reconfiguration is studied. Encoding mode based on basic loop is adopted, new crossover mode is introduced, new mutation mode and inversion operator are put forward. For acceptance mechanism of new answer, Metropolis rule of simulated annealing is introduced. It is proved that the mixed genetic annealing algorithm can solve the problem of distribution reconfiguration effectively.
