    Evaluación de pérdidas de potencia activa en el sistema eléctrico de la Empresa Eléctrica Quito (EEQ) aplicando un Algoritmo de optimización
    (Ecuador: Latacunga: Universidad Técnica de Cotoapaxi (UTC), 2024-08) Pereira Herrera, Luis Andrés; Saraguro Ramírez, Roberth Alcides
    This research proposes to develop a methodology based on the mean-variance mapping optimization (MVMO) algorithm to reduce the active power losses of the sub-transmission system of Empresa Electrica Quito (EEQ), determining the best operating point of the system, considering the state of tap’s of the transformers, the capacitor banks and the contribution of reagents from the generation plants that EEQ currently has. The same ones when operating in a proper way lead to reduce the value of active power losses in the network, thus improving the operating conditions of the EEQ’s Electrical Power System.

    The present research addresses the implementation of a photovoltaic system, which is defined as a set of technologies that harness solar radiation to generate electricity directly through the photovoltaic effect. It is mainly composed of photovoltaic solar panels that capture sunlight and convert it into direct current electrical energy. In addition to the solar panels, a typical photovoltaic system includes components such as inverters, storage batteries, charge controllers, and mounting structures. The study aimed to design and implement a photovoltaic system for the lighting systems, closed-circuit television, and data system in the offices of Enginsmart S.A. According to the methodology, applied research with a quantitative approach, non-experimental design, and fieldwork was conducted, and the software PVsyst version 7.4 was used. Regarding the simulation results, it is observed that the power generated by the photovoltaic system is significant, with high energy generation efficiency and a notable reduction in CO2 emissions. It is concluded that to meet the daily energy demand of 26,814 watts, it is necessary to implement 12 solar panels connected in 4 series of 3 modules, 8 12V batteries connected in series with a voltage capacity of the battery pack of 96V connected to an inverter with a power of 3KW, current of 80A, and a voltage between 48-110V, adjusted to the 96V voltage of the battery pack..

    Desarrollo de un modelo de evaluación técnico económico para la optimización de inversiones en micro generación fotovoltaica en la granja avícola “Damiancito” en el cantón Pelileo, provincia de Tungurahua.

    Currently, the search for sustainable and economically viable energy alternatives is of great importance for the agro-industrial sector, especially for poultry farms, where energy consumption is a key factor for the operations and profitability of a company. The present research work focuses on the development of a technical-economic evaluation that can optimize investments in micro solar generation in the poultry farm, considering both technical and financial aspects. The use of photovoltaic systems in poultry farms not only promises to reduce traditional energy consumption and associated operating costs, but also to reduce the environmental impact of these operations. However, the profitability of these systems depends on several factors, such as geographic location, local climatic conditions, and the correct design and installation of the photovoltaic system. In economic and financial research, the profitability of the project is evaluated using indicators such as the Net Present Value NPV and the Internal Rate of Return IRR. These indicators are necessary to determine the profitability of investing in micro photovoltaic generation. The NPV is a measure that allows us to know the present value of the future cash flows that the investment will generate, on the other hand, the IRR is the discount rate that makes the NPV equal to zero. For the mathematical calculations part, specifically the optimization of the model, the AMPL program is used, which allows the information to be parameterized and models the maximization of economic benefits of the photovoltaic system.

    Análisis del uso y la producción de la energía eléctrica de un sistema híbrido fotovoltaico-eólico en la azotea de un edificio de educación
    (Ecuador: Latacunga: Universidad Técnica e Cotopaxi (UTC), 2024-08) Vaca Ortega, Gabriel Alejandro; Salazar Achig, Edgar Roberto
    The project presents the feasibility of implementing a hybrid electricity generation system that combines wind and photovoltaic sources on the rooftop of a building at the Instituto Superior Tecnológico Tungurahua, in response to high energy consumption costs and power outages in Ecuador. The main objective is to carry out an analysis of the use and production of electrical energy through simulations, in order to reduce the billing of consumption in educational facilities. The methodology employed includes a quantitative approach, with phases that cover the collection of data on the electrical demand and historical consumption of the building, as well as the measurement of climatic variables using a weather station. A coincidence analysis between energy use and generation will be carried out, followed by the modeling and simulation of the hybrid system using specialized software. The results will allow evaluating the technical, economic and environmental viability of the project, identifying the system's capacity to reduce electricity consumption and generate significant monetary savings for the institution. This study will not only contribute to the energy sustainability of the campus but will also serve as a replicable model for other educational institutions in the country, promoting the use of renewable energies and energy efficiency in the Ecuadorian context.

    Estudio y simulación de coordinación de protecciones para mejorar la continuidad de servicio en la empresa Aglomerados Cotopaxi S.A.
    (Ecuador: Latacunga: Universidad Técnica de Cotopaxi (UTC), 2024-08) Casa Chancusig, Luis Franklin; Barbosa Galarza, José Efrén
    In this degree work, the coordination of protections of the electrical system of the company Aglomerados Cotopaxi is analyzed. To do this, the ETAP software is used, where each detailed element is modeled in the one-line diagram of the company's electrical system. Based on this simulated model, the initial conditions of the system are calculated to define aspects such as the load level of the elements and lines, considering the presence of loads at nominal values. Next, a failure analysis and a protection coordination study are developed, defining failure scenarios in different bars of the system and evaluating the performance characteristics of the protections. Additionally, a technical-economic analysis is carried out, which considers historical energy consumption data in the industrial plant, records of the number of hours of power outages and other energy quality parameters. This analysis is related to the costs derived from the company's production loss times, both on a monthly and annual level.
