Estudo de viabilidade da geração distribuída por sistemas fotovoltaicos conectados à rede elétrica em Curitiba

Abstract

The increase in energy demand in Brazil means that the country has to invest increasingly more in generation of electric energy, where the demand for other renewable sources increases gradually, since they have a smaller impact on the environment. The diversification of a country's energy matrix is important in order to do not hust it in just one method of generating energy. The use of photovoltaic systems is a viable solution for the country, where it presents favorable natural conditions for use of solar energy. This work approaches the current cenario of the Grid-Connected PV Systems installed in Curitiba, as well the installed potential. By means of performance parameters, performance analyzes of three PV Systems installed in the city were made during the year 2016 and part of 2017, namely: Curitiba Campus Downtown and Neoville, both located at the Federal Technological University of Paraná (UTFPR), as well as a residence. In order to measure the time of return of the initial investment in its installation, a study was made of the economic viability of these systems according to the tariff model in force in Brazil through economic engineering tools: Simple Payback and Discounted Payback, Net Present Value (NPV) and Internal Rate of Return (IRR). Finally, the application of the saved value of electric energy bills was simulated in an income application during the useful life of the system.
