Dimensionamento de um sistema fotovoltaico off-grid para alimentação de um reator de hidrogênio

Abstract

This undergraduate thesis presents the simulation and sizing of an off-grid photovoltaic system designed to provide continuous power supply to a hydrogen reactor. Considering the often precarious energy supply conditions, especially in regions distant from urban centers, the development of an autonomous power generation system capable of maintaining a reliable and continuous energy supply is proposed. The objective is to determine the ideal generation capacity, taking into account all conversion and conduction losses, as well as local shading effects that may negatively impact solar radiation capture, in addition to the appropriate storage capacity required for the reactor's continuous operation. The calculations will initially be performed empirically and subsequently validated through software simulations to ensure greater accuracy and reliability. As a result, this study will present a complete system capable of supplying power to the reactor, which has an energy demand of approximately 4,320 Wh/day, while providing up to 48 hours of uninterrupted operational autonomy. Additionally, an economic feasibility analysis will be conducted, considering the expected savings, investment costs, and payback period. This analysis will indicate the applicability and potential benefits of investing in this type of energy system.
