A mathematical optimization technique for locating and sizing distribution substations, and deriving their optimal service areas

Abstract

The problem discussed in this paper is the planning of distribution substation locations, sizes, and service boundaries. The technique discussed uses operations research methods to simultaneously optimize substation sizes and service boundaries, given alternative locations for the substations and reliability constraints. The results of the discussed techniques will lead to a configuration of substations that will minimize distribution feeder losses and substation construction costs. Adherence to the results will lower long-range distribution expenses.
