Simulação de um sistema fotovoltaico on grid: um estudo aplicado no Centro de Desenvolvimento Sustentável do Semiárido - CDSA.

Abstract

Photovoltaic energy is a form of renewable energy that utilizes sunlight to generate electricity. This technology has become increasingly popular due to its economic and environmental benefits and plays an important role in the global transition to cleaner and more sustainable energy sources. In general, the consumer installs, generates and consumes its own energy, the surplus is distributed with the dealer, and can be used in up to 5 years. Until 2021, there was no taxation, but in January 2022, PL 582 was converted into the law 14.300, called “taxation of the sun” that applies to the distribution wires. Still, the application of photovoltaic systems remain profitable and with a growing percentage of contractors in recent years, having an increase of 84% in the year 2022(ano em que a lei entrou em vigor). In order for this process to take place, an initial investment is required. And this work aims to simulate the application of a photovoltaic system on grid at the Semiárido Sustainable Development Center (CDSA) of the Federal University of Campina Grande -UFCG. It is an exploratory and applied study. It applies to which a Simple Pay Back that simulates the return time invested and also the savings generated by the system, where the Campus would have its own photovoltaic power plant. The results allowed to develop an On Grid system of autonomous generation of clean and sustainable energy, where through a tool developed in the software itself, it was possible to measure the return time invested and the amount of energy generated having a complete view of the project simulated in the CDSA. Finally, it was possible to reach satisfactory conclusions, enabling an estimated value of R$ R$ 1.640.235,04 of return invested in only 4 years, with an average generation of 44.062 kWh/month meeting the needs of the Campus generation a achieved economy, providing the university an immediate or future application of the project.
