Reconfiguración de sistemas eléctricos de distribución en medio voltaje, utilizando técnica metaheuristica

Abstract

The reconfiguration of medium voltage distribution power systems is a useful technique to obtain optimum system performance in the event of failures caused by force majeure events (shocks, natural disasters), taking into consideration pre-established system restrictions. The present study addresses this problem in 4 stages, the first by means of OSM georeference the study area, the second stage geographically locates the network infrastructure (poles, transformers), the third stage using the information obtained in stages 1 and 2 is analyzed using metaheuristic technique focused on the PRIM algorithm and the use of minimum spanning tree (MST), The algorithm's effectiveness in the face of system failure events is subsequently analyzed by means of case studies, demonstrating its effectiveness and short computational processing times, to validate the results of the algorithm from the electrical point of view through the use of the Cymdist tool, the system elements are parameterized and the case studies are tested through power flows, it is evidenced that the system recovers in the extreme case of simultaneous failures in different areas of the system despite the fact that the affection was 43.07%, the current flow is analyzed in node 496 one of the most distant from the substation in which a decrease of 78.59% is evidenced due to the load sharing.
