Optimal sectionalizer allocation in electric distribution systems by genetic algorithm

Abstract

This paper presents an economics based model of sectionalizer allocation in single radial feeder distribution systems. The model considers both cost of energy losses and capital investment in the sectionalizer installation. The cases when sectionalizers are not fully reliable and when they may cause additional short-circuits are investigated. To solve the problem of optimal sectionalizer allocation a genetic algorithm based procedure is developed. An illustrative example is presented. © 1994.
