A new method for planning secondary distribution networks

Abstract

The electrical distribution system is the part of the power systems that connect the primary substations to the street transformers (primary system) and these to the consumers (secondary system). Due to the low voltage levels, it is in the distribution systems, particulary in the secondary system, where occur most of the system losses. The greenfield secondary network planning problem always appears when a new area needs to be supplied. Therefore, well planned networks, even when small gains are obtained, may yield a large final savings due to the great number of times the procedure is repeated. In this work we present a new 2-phase planning methodology that has shown to present cost reducti..
