This paper presents a methodology for distribution networks automation planning. The presented methodology identifies the optimal location of intelligent protection devices for improving network reliability. The approach also analyzed the available back-feeding for implementing an IEC 61850-based smart automation system logic. The back-feeding routes of each feeder are evaluated by comparing suitable performance indexes identifying the more appropriate one able to resupply the considered feeder for most of the potential faults. Of course, topological and electrical constraints have to be fulfilled, and therefore the simulations consider feeder and substation constraints. Thanks to the data given by the local system operator Unareti, the methodology has been tested on a real distribution network located in the South-West area of Milan.

Abstract

This paper presents a methodology for distribution networks automation planning. The presented methodology identifies the optimal location of intelligent protection devices for improving network reliability. The approach also analyzed the available back-feeding for implementing an IEC 61850-based smart automation system logic. The back-feeding routes of each feeder are evaluated by comparing suitable performance indexes identifying the more appropriate one able to resupply the considered feeder for most of the potential faults. Of course, topological and electrical constraints have to be fulfilled, and therefore the simulations consider feeder and substation constraints. Thanks to the data given by the local system operator Unareti, the methodology has been tested on a real distribution network located in the South-West area of Milan.
