ABSTRACT: Abstract- In this paper, a novel approach usingapproximate reasoning is used to determine suitablecandidate nodes in a distribution system for capacitorplacement. Voltages and power loss reduction indices ofdistribution system nodes are modelled by furzymembership functions. A fuzzy expert system (FES)containing a set of heuristic rules is then used todetermine the capacitor placement suitability of eachnode in the distribution system. Capacitors are placed onthe nodes with the highest suitability. a new designmethodology for determining the size, location, type andnumber of capacitors to be placed on a radial distributionsystem is presented. The objective is to minimize the peakpower losses and the energy losses in the distributionsystem considering the capacitor cost. Test results havebeen presented along with the discussion of the algorithm.
