CAPACITOR PLACEMENT IN DISTRIBUTION SYSTEM USING ANT COLONY OPTIMIZATION ALGORITHM
Raviraj R. Nirmal,  Alpesh S. Adeshara
Electric power supply system comprises of generating units that produce electricity, high voltage transmission lines & distribution lines that deliver the electricity to consumers. Losses mainly occur in distribution system due to variation in the load and the low voltage level at which electricity reaches to consumer. To optimize reactive power we must minimize total active power loss and control of voltage. This can be achieved by placing capacitor at proper locations in electrical distribution system. The optical capacitor placement problem involves determination of the location, number and size of capacitor to be placed. This paper describes a comparative study of capacitor placement problem using fuzzy logic approach described in "Cost Saving in Distribution System Using Fuzzy Techniques" and a novel method which solves problem using Ant Colony Optimization algorithm. Both the methods were applied as a simulation on a 15 bus radial system. It has been proved with the results that ACO method solves the problem with higher accuracy and also in a smaller span of time.
