Análise da viabilidade da geração híbrida de energia solar e eólica no Nordeste brasileiro.

Abstract

In view of the energy crisis that reaches Brazil, it arises the need to study suitable alternatives that contribute to the energy matrix. This study presents a proposal for energy hybrid system, which allows simultaneously the use both solar and wind energy, thus addressing the goal of how to assess the sustainability of wind and solar hybrid generation can contribute to the sustainable development of the Brazilian Northeast, through its energy matrix. To achieve this objective, it was necessary to identify the solar and wind potential in Northeast Brazil for the period 2010 and 2011, resulting in the construction of solar power Complementarity Map and Wind, which has the best potential for solar and wind power, indicating concurrency through a hybrid system. Through this analysis it emerges the need to use and adaptation of sustainable energy development indicators, contributing to determining the most favorable regions in terms of topography and hydrography, and at the same time determine the lowest environmental impact for tourism. For this result, it was necessary to identify and adapt a model Energy Indicators for Sustainable Development - IEDs, the model used was proposed by the IAEA. For the use of these indicators, the competent sources of data were used such as the Ministry of Mines and Energy, Embrapa, EPE and Abrelpe, developing an analysis adapted from IEDs. Thus, the hybrid systems of solar and wind energy, proved amenable and organic, including the production of power distribution storage systems. The complementarity map generated by the numerical model: Brazilian developments on the Regional Atmospheric Modeling System - BRAMS, presented the ideal areas for application of hybrid systems, which could be perceived from the northeastern states: Rio Grande do Norte, Paraiba, Pernambuco, Alagoas, Sergipe and Bahia, the others had lower standards. Thus, excluding the coastal strip, corresponding to the tourist area, which should be strategically guarded, the solar and wind variation intervals are indicated which are in the range 1250-1350 (kWm-2h-1), described and analyzed areas by during the work area.
