Diseño Óptimo de Topologías en Microrredes Eléctricas Bajo Consideraciones de Eficiencia y Acople Sectorial

Abstract

This research project addresses the optimization of multimodal electrical microgrids, considering their topology, operation mode, sector coupling elements, and load type. The objective is to determine the optimal topology that minimizes microgrid costs. To achieve this, a case study methodology was employed, developing load consumption models, distributed energy resources (DER), and sector coupling elements for each typical day of the year. Various electrical microgrids were designed with different topologies, bus voltages, and load types, considering the necessary converters and their efficiency. Based on the information obtained from the models, a mixed integer linear programming (MILP) optimization problem was proposed to minimize costs. This type of model is suitable for linear problems that include binary and continuous variables. The results demonstrate that the AC topology microgrid in isolated operation mode generates the lowest cost, primarily using AC load. This is because the AC topology requires fewer converters, which have a higher individual cost. In summary, this project provides an optimal multimodal electrical microgrid considering various factors that influence its cost. AC topology in isolated operation mode with majority AC load is presented as the most economical option for the analyzed case study.
