Network reconfiguration for loss reduction in distribution network with distributed generation

2016 
This paper proposed a novel algorithm of network reconfiguratoin based on improved quantum particle swarm optimization (QPSO), which can be used for loss reduction in distribution network with distributed generation. First, the network topology is analysed on the basis of branch loop incidence matrix and layered branch incidence matrix. Second, calculate the network loss by layered forward-backward sweep method. Then, an improved QPSO is proposed where the disturbance factor is introduced, based on which the network reconfiguration is put forward. Finally, the proposed algorithm is proved to be effective by applying to PG&E69 bus system and the Tai-Power 11.4-kV distribution system.
