Analytical Method of Capacitor Allocation on Distribution Primary Feeders

This paper reports the development of an analytical method to determine the best capacitor locations, reactive compensation level, and yearly loss reductions under a wide range of annual reactive load conditions for use in distribution system design. The results show that, not only is more than 80 percent yearly loss reduction possible with non-switched capacitor banks, but also optimum reacttve-compensation level and maximum yearly loss reduction can be expressed in a simple mathematical equation.
