Metodología para evaluar la flexibilidad técnica operativa de un conjunto de recursos energéticos distribuidos (DERs) como mecanismo para facilitar la integración de la generación distribuida

Abstract

This thesis focuses on the analysis of a methodology for evaluating the model the operational flexibility of a set of distributed generation units, essential for their effective integration into the electric power system. The initial overview of the work explores distributed generation, defining key concepts and examining its current status in Ecuador through installed projects and current regulations. In addition, it delves into the international understanding of Operational Flexibility, reviewing its evolution and defining the perspective adopted in this study to use this concept. The proposed methodology employs metrics such as operating power, power ramp and energy storage to define a volume of flexibility of Distributed Energy Resources (DER). The study is performed in three phases: analysis of the individual flexibility of each DER, followed by an aggregation to calculate an overall flexibility volume and finally an evaluation by comparing the available flexibility with the flexibility required to establish that it is sufficient. Python was used for graphical representations and Excel for data analysis. Validity was checked by simulations of IEEE base models with OpenDSS and MATLAB, showing consistency in the results.
