Power Loss Reduction And Voltage Profile Improvement In Distribution System Using Network Reconfiguration And Capacitor Placement

Power loss reduction and voltage profile improvement are goals for electricity utilities. Distribution system reconfiguration and optimal capacitor placement are two of the low Cost available tools for Power loss reduction and voltage profile improvement. Reconfiguring the network means altering its topology by changing the status of normally opened and normally closed switches. This paper propose the use of plant grows simulation algorithm (PGSA) to optimize the distribution system reconfiguration with the aim to minimizing the active power losses, considering as constraints the radial characteristics of the distribution networks and feeder capacity. Also has been suggested the use of OCP environment in ETAP software to optimal capacitor placement to improve the voltage profile. The proposed method is tested on 33 bus test system and the results are significant
