Modelación y validación del regulador de voltaje de la central hidroeléctrica el Ambi utilizando optimización heurística MVMO y registros de mediciones sincrofasoriales para contribuir al análisis operativo del sistema nacional interconectado

Abstract

This document deals with presents a detailed methodological approach for the modeling and optimization of the automatic voltage regulator (AVR) in the El Ambi Hydroelectric Power Plant. It commences with a technical depiction of the facility, detailing its geographical placement and variations in the AMBI River's flow, influencing the production of energy. The consistent oversight by the regulatory body (CENACE) and the substantial role played by the facility in meeting Ibarra's electricity requirements are emphasized. The test protocols implemented are explained, focusing on the performance of the "Voltage GeneratorRegulator" system. The essential requirements for carrying out evaluations are detailed, focusing on controlled changes of the reference voltage and their impact on the system. Following this, the application of the findings in PowerFactory is elucidated, establishing a coherent connection between theoretical concepts and practical application. The optimization of the parameters of the AVR is addressed by a specific algorithm, such as the "MeanVariance Mapping Optimization" (MVMO). The method's efficacy is showcased through the reduction of errors between simulated signals and those acquired during field tests. The consistency between the MVMO results with another heuristic algorithm is compared and highlighted, underlining its robustness and applicability in voltage regulator modeling.
