Expansion planning problem in distribution systems with reliability evaluation: An application in real network using georeferenced database

•We present a methodology for expansion planning problem in distribution systems.•The methodology consists of two stages involving the MILP model and reliability.•An application with a friendly interface was developed.•The application allowing the communication between the GIS system and model.•Good solutions in acceptable computational time was found for large real network.

This paper present a way to insert the reliability in models of expansion planning of electrical network from real data coming from georeferenced database of Geographic Information System (GIS) of the company. For this an software with a friendly interface was developed, a real network is used as an example and computational results are presented.
