Solar energy, Wind energy, Hybrid system


With many renewable energy sources available, the combination of them becomes an interesting investigation. The hybrid photovoltaic, wind, battery system is a combination of solar and wind energy with a battery bank for energy storage, and it has been widely studied in the last years. Such a hybrid system has been shown as a solution for many energy problems around the world, and then it must be analyzed to applications in Brazil intending to investigate in which regions it could be applied with the purpose of making the most efficient and cheap energy generation. In this paper is described a study about the viability of this hybrid system for some regions of the country. Each subsystem is sized based on global irradiance, wind speed data and load demand. The percentage of the generation subsystems required to supply the load demand is calculated, and then the most efficient combination is selected. Each region has its own climatic characteristics, which implies that the most efficient system is composed of a different combination of the subsystems. Most of Brazilian territory has high availability of solar energy; on the other hand, wind power is more restricted on some areas, hence the proposed hybrid system is restricted to where there is availability of both sources, which represents many inland and coastal regions of Brazil. The technological development of these subsystems and its observed potential for many regions shows that the analyzed hybrid system is a good alternative for energy solutions in many locations of the country.
