Item Evaluación del funcionamiento de un sistema de bombeo fotovoltaico para el sistema de riego de cultivos hidropónicos de la granja agropecuaria la victoria del Cantón Cevallos Tungurahua(2023-11) Aguirre Sánchez, Víctor Fabián; Laverde Albacerracín, Cristian SamuelEs pertinente señalar que debido a los recientes cambios a nivel global, la energía solar fotovoltaica se ha vuelto cada vez más común y versátil, con una creciente variedad de aplicaciones. Aunque la captación de energía solar no es una novedad, su utilidad ha evolucionado con el tiempo. Por lo tanto, el propósito de esta investigación es evaluar el desempeño de un sistema de bombeo fotovoltaico para su implementación en un sistema de nebulización en la Granja La Victoria. Se utilizó un enfoque metodológico cuantitativo, basado en cálculos estandarizados y precedentes nacionales e internacionales, con un diseño pre-experimental para abordar la hipótesis y medir las variables. Además, la investigación se caracterizó por ser documentada, exploratoria, explicativa y de campo. Los resultados de la simulación y la implementación práctica del sistema indican que dos paneles de 345 W en configuración paralela, una bomba periférica de 373 W y un inversor MPPT-CA de 1kW son adecuados para satisfacer las necesidades energéticas del proyecto (1.636 Wh/día). En términos de eficiencia, se logró un rendimiento del sistema del 89,40%. Además, la eficiencia de la bomba, considerada como un equipo xiv unitario, alcanzó el 61%, mientras que la eficiencia de la bomba como parte del sistema fotovoltaico alcanzo el 51%. Finalmente, en lo que concierne a la protección del medio ambiente, la reducción de dióxido de carbono (CO2), metano (CH4), óxido nitroso (N2O) y gases fluorados es crucial. La implementación del sistema presentado en este estudio se espera que reduzca 0,97 𝑚3 /día de CO2. En resumen, se debe promover activamente la investigación y la aplicación de sistemas fotovoltaicos altamente eficientes en diversos sectores, especialmente en el cantón Cevallos, que se caracteriza por ser un área agroindustrial en pequeña escala, ya que existen planteles avícolas, cultivo de flores, crianza de animales menores, así como el cultivo de legumbres y cereales.Item OPTIMIZACIÓN DEL ALMACENAMIENTO DE ENERGÍA PARA INTEGRACION FOTOVOLTAICA EN DOMICILIOS UTILIZANDO MATLAB(Universidad Tecnica de Ambato,Magister en Energías Renovables, 2022-10-05) Sosa Guzmán, Andrés David; Cuenca Sánchez, Alan DanielCurrently, the use of photovoltaic solar energy has increased significantly worldwide, as it is considered clean, inexhaustible, and environmentally friendly. Furthermore, it drastically reduces the environmental impact of CO2 emissions by a total of 840 (kg CO2) per year. In fact, photovoltaic systems can be of two types: off-grid when it is difficult to access the electrical distribution system and grid-connected when it can provide or receive energy from the electrical system. This project focuses on off-grid systems and proposes control strategies for optimizing battery bank energy storage. Therefore, the following scenarios were considered in a Matlab simulation: a photovoltaic system without optimization, the oversizing of a photovoltaic system, a photovoltaic system with demand management, a photovoltaic system with auxiliary generation, and a hybrid system (photovoltaic - auxiliary generator) with demand management. The most representative findings indicate that the use of a hybrid system allows recovering the battery state of charge (SOC) by 1.8% per day, satisfying the needs of the users and including shading conditions in its analysis. Additionally, a levelized cost of energy (LCOE) analysis was performed for each scenario mentioned, for which the hybrid system presents a LCOE of 44.1 (cUSD/kWh). This means that the application of a hybrid system is feasible in homes that do not have access to the distribution network. Finally, the result of this analysis contributes to the implementation of hybrid systems in off-grid systems. In addition, it contributes to homes connected to the grid to drive photovoltaic energy to reduce the environmental impact produced by the CO2 footprint and the load on the distribution system.Item Estudio de sostenibilidad con energía fotovoltaica para el abastecimiento de electricidad al sistema de agua del barrio Mariscal Sucre(Universidad Técnica de Ambato. Dirección de Posgrado. Maestría en Energías Renovables., 2022-11-01) Chiliquinga Chariguamán, Diego Armando; Gordon Gallegos, Carlos DiegoThe amount of rain in the Mariscal Sucre neighborhood is insufficient to meet the water demand of the agricultural and livestock sector. Extraction and pumping methods with electricity supply from the distribution network have a high cost, therefore, it is an unsustainable option for the inhabitants. For what makes PV-based solutions more attractive, according to the literature, only about 10% of the total energy produced by PV modules is used to meet the world's water needs. Currently, the water supply for the neighborhood, whether for human consumption and irrigation, is carried out by extracting water from a deep well with the help of an electro-submersible pump, which is fed with energy from the distribution network. The cost of electricity supply in 2015 was around $150, which according to the inhabitants was affordable, but as of 2020, when the rains decreased drastically in the sector, the need for water supply for irrigation was insufficient, so the pump it remained on most of the day, increasing electricity consumption and therefore the increase in energy payments. The objective of this project was to determine the sustainability of the energy supply to the water system with photovoltaic energy, for which it began by calculating the solar resource of the site with the help of available databases, additionally, with the help of the electricity consumption history. Issued by the distribution company (ELECPCO S.A.) from 2015 to 2022, the average consumption profile of a typical day was obtained. To verify the optimal dimensioning of the photovoltaic generator, the analytical method and the PVSYST software were used. The dimensioning was carried out using the criteria of a system isolated from the network, with which the following configuration was determined: 32 solar panels (405 W-STC), a regulator that supports a minimum current of 28.55 A, an inverter with two channels of 6.87 KW minimum, and 60 batteries of 250 Ah for an autonomy of two days recommended in the Ecuadorian Electrical Standard (NEC-11).
