Abstract: This paper describes a two-stage methodology of optimal capacitor placement for the reconfigured network. A two-stage methodology is used to reduce the losses and to improve the voltage profile of the balanced radial distribution networks. In the first stage, an improved fuzzy multi-objective algorithm is used for the network reconfiguration of the original network. In the second stage, capacitors are placed optimally for the reactive power compensation of the reconfigured network. Fuzzy approach is used to find the optimal capacitor locations and analytical method is used to find the sizes of the capacitors. The proposed method is tested on 11-bus, 33-bus and 69-bus test systems and the results indicate that considerable loss reduction is possible with substantial improvement in the voltage profile.
