Complementaridade entre sistemas híbridos eólico-solar: estudo de caso do Parque “Fontes” em Tacaratu-PE

Abstract

After the blackout crisis, which culminated in Brazil in the early 21st century, the energy matrix model, predominantly hydroelectric, which had a weakly interconnected power system, got worn. At the same time the increase of technology and quality of life, which are naturally associated with an electricity consumption raise, made it clear that the country could not depend on a single source of power generation, who is vulnerable to the rain cycle. At present the questions about an essentially hydroelectric energy matrix have surfaced in a new moment of crisis, whose consequences are seen in the high taxes practiced. This context combined with sustainability stimulates the search for new energy sources that are renewable and cleaner. In order to discuss proposals for the diversification of the energy matrix in order to ensure the supply of electricity with reduced environmental impacts is positioned this work, where the main subject is to evaluate the daily complementarity of the generation complex Fontes, located in the city of Tacaratu, state of Pernambuco, that makes use of solar photovoltaic and wind sources. The main obstacle to the use of solar photovoltaic or wind generation as sources of solid energy is their seasonality. In order to overcome this problem, one strategy to be used is the implementation of hybrid generation plants, where one energy source mitigates the effects that seasonality imposes on the other, with a mutual relationship. In the case of the Fontes system, the installed capacity is 90.9 MW, 11 MW in photovoltaic modules and 79.9 MW in wind turbines. Therefore, the present paper, based on a real case analyze, in addition to daily complementarity, the advantages obtained by a solar-wind hybrid system, in terms of guaranteeing the supply of electricity over the 24 hours a day, with generation data from one entire year. Other advantages that makes feasible the implementation of plants similar to the one discussed in this paper are also presented.
