PROPOSED STRATEGY FOR CAPACITOR ALLOCATION IN RADIAL DISTRIBUTION FEEDERS

Capacitors in power systems are generally used to supply reactive power for the purpose of loss minimization and voltage profile improvement. The main objective of this study is to present a new strategy for capacitor allocation in radial distribution systems. Presently, the capacitor placement problem is widely solved by using heuristic optimization methods. In this study sizes and locations of capacitors are selected in order to achieve the maximum reduction in total losses of the system. This reduction is not seen in all branches at times, but the loss in any individual branch of the system is not allowed to increase than it was before the capacitor is placed. This work is done applied to 34-bus distribution system. The results of this proposed strategy are compared with original previous work mentioned to show its validity. Power loss and voltages in buses for both cases are obtained by simple load flow technique.
