Planificación de redes eléctricas de distribución en zonas urbanas consolidadas considerando criterios de confiabilidad.

Abstract

An underground electrical distribution networks planning methodology in consolidated urban areas is described and it implemented through a computer program of academic type developed in m. language of Matlab®. Methodology focuses on determining the optimal economic cost for the location of the MV/LV transformation centers and the open loop configuration of the medium voltage network that feeds them, based on reliability criteria and using the information which resides in the geographic information system database (GIS) of the Ecuadorian electrical distribution utilities as input parameters. The proposal contemplates use of several metaheuristic algorithms, optimization with graph theory and clustering. The optimization process takes into account compliance with limits for voltage drops in low voltage circuits, improvement of service reliability indexes and the sizing of MV/LV transformers based on the REA method. Finally, the proposed methodology is applied in two consolidated urban areas Ambato city that are currently supplied, one through an aerial network and the other through an underground network. By means of the present work, the underground electrical distribution network planning of the cities urban areas is synthesized.
