Evaluación de la confiabilidad de un sistema de distribución con integración de tecnología vehículo a red usando el método Montecarlo

Abstract

The present work proposes the evaluation of reliability in electrical distribution systems when electric vehicles are integrated; also, the insertion of automatic reclosers is proposed to improve the reliability of the system. The methodology used for the reliability evaluation is through the Monte Carlo simulation under the two-state model for a repairable component, which is used in the Matlab software. Under the Monte Carlo simulation, the failure and repair times are obtained, which are necessary to calculate the reliability indexes by means of the PowerFactory software. For the evaluation and analysis, the modified IEEE 33 bars are used, where two study cases are proposed: without insertion of electric vehicles and another with different scenarios of 50%, 75% and 90% of electric vehicles insertion, then an alternative measure is proposed to improve the reliability of the system which is supported by the placement of automatic reclosers. By means of the evaluation and analysis of the system, the SAIFI and SAIDI indexes increase their value as the percentage of electric vehicle insertion increases progressively, this results in a reliability shortfall, and automatic reclosers are incorporated to support this shortfall.
