DISEÑO, IMPLEMENTACIÓN Y PRUEBAS DE UN SISTEMA PARA LA EVALUACIÓN DE ALGORITMOS DE BÚSQUEDA DE MÁXIMA POTENCIA PARA CELDAS SOLARES (DESIGN, IMPLEMENTATION, AND TESTING OF A SYSTEM FOR THE EVALUATION OF MAXIMUM POWER POINT TRACKING ALGORITHMS FOR SOLAR CELLS)
Resumen
Este trabajo presenta el diseño, implementación y pruebas de un sistema de evaluación para algoritmos de busqueda de máxima potencia (MPPT) en aplicaciones fotovoltaicas (PV). La plataforma de pruebas utiliza un emulador fotovoltaico para simular una celda solar que opera bajo las condiciones de irradiación y temperatura deseadas. Un microcontrolador se programa con el script del algoritmo de MPPT a evaluar. Basado en esto, el microcontrolador envia la señal de control a una placa de potencia con un convertidor tipo boost para llevar al sistema a un punto de operación determinado. Por último, las mediciones requeridas por el estándar de pruebas se registran en una base de datos para su posterior análisis. Se comprobó que la plataforma implementada simuló satisfactoriamente el comportamiento del algoritmo seleccionado de acuerdo con lo reportado en la literatura. El objetivo principal del trabajo es facilitar la creación de plataformas de prueba para diversos sistemas de control en aplicaciones fotovoltaicas.

Abstract
This work presents the design, implementation, and testing of a system that evaluates maximum power point tracking (MPPT) algorithms for photovoltaic applications. The test platform integrates a photovoltaic (PV) emulator to simulate a solar cell that operates under the desired irradiance and temperature conditions. A microcontroller is programmed with the script of the algorithm being tested. Based on this, the microcontroller sends the control signal to a boost converter that drives the system to the operating point determined by the MPPT algorithm. Lastly, the measurements required by the test standard are stored in a database for further analysis. The implemented platform successfully simulated the behavior reported in the literature of the selected algorithm. The main objective of this work is to accelerate the creation of tests platforms for diverse control systems in photovoltaic applications.
Keywords: MPPT, Photovoltaic, Test-platform.
