Análise técnica e econômica de microgeradores eólicos com foco em produtos comerciais para residências unifamiliares

Abstract

In Brazil, the use of wind in Brazil has been increasing and its participation in diversification of the energy matrix. It is one of the main sources of clean and sustainable energy. However, most projects and products on the market have an emphasis on wind energy generation with high power systems, which requires a higher investment. The goal of this work is to perform a technical and economical analysis of the use of commercial grid tie micro wind generators to meet the energy demand of a single-family residence in Santa Vitória do Palmar, Rio Grande do Sul, using current and actual data rates and charges. In the elaboration of this work, 16 scenarios were simulated with three different types of wind turbines according to the present ANEEL tariff flag system. For the economic analysis, the Net Present Value, Internal Rate of Return, Simple Payback and Discounted Payback methods were used, along with the LCOE methodology to compare the cost-effectiveness ratio. For the technical analysis, it was considered the minimum, nominal and maximum speed of each wind turbine, as well as the power and the electric energy generated from the power curve, the energy demand of the residence and the Weibull distribution probability, the speed and the direction of the winds in the city. In conclusion, this work reached its goals showing six scenarios technically and economically feasible, four ideal scenarios with a residence of higher consumption and two real scenarios.
