Propuesta de diseño de un sistema fotovoltaico en media tensión de 1,842 MWP, con conexión a la red en un centro de distribución

Abstract

The technical project prior to obtaining the Electrical Engineer degree develops the design proposal of a grid-connected photovoltaic system in medium voltage, with an installed capacity of 1.842 MWp, intended for a distribution center, in order to reduce dependence on the conventional electrical supply, optimize energy consumption, and contribute to environmental sustainability. The increase in energy demand and the high operational costs associated with the use of the conventional electrical grid make it necessary to implement solutions based on renewable energy sources, with solar photovoltaic energy being an efficient, reliable, and sustainable alternative. The applied methodology is based on the collection and analysis of historical energy consumption data from the distribution center, the study of the geographical and meteorological conditions of the site, and the technical sizing of the photovoltaic system. The distribution design of the photovoltaic modules was carried out using AutoCAD, including the development of single-line diagrams for interconnection, protections, and inverters, as well as the selection of appropriate equipment according to the technical requirements of the project. Additionally, the specialized software PVsyst was used to simulate system performance, validate electrical parameters, and estimate annual energy production. The obtained results demonstrate the technical and energetic feasibility of the system, showing significant energy generation that reduces the consumption from the electrical grid and decreases operational costs. Furthermore, the environmental analysis reflects a considerable reduction in carbon dioxide emissions, contributing to environmental protection. In conclusion, the implementation of the photovoltaic system represents an efficient, sustainable, and viable solution to improve the energy efficiency of the distribution center.
