New Reduction Technique for Distribution Feeders

Abstract

A unique method is developed for reducing the distribution feeders, both for series and parallel configurations, by combining the discrete distributed load voltage drop solutions and discrete distributed line losses solutions. The reduction method may be applied to represent a feeder or few feeders with distributed loads by a point load and a fictitious section connected at an equivalent length. To match both voltage drop and line losses, fictitious section represents a load or generation. The suggested method herein, while preserving the accuracy of Vempati's method for series configuration when dealing with distribution feeders containing parallel laterals, gives a higher degree of accuracy compared with other methods, including Vempati et al. [10].
