Integração e complementaridade de fontes de energia solar e eólica em configurações híbridas : um estudo de caso

Abstract

This paper included an evaluation of the technical and economic feasibility of using different technologies in hybrid configurations of electric power generation systems. The results of computer simulations performed in the SAM (System Advisor Model) software of NREL (National Renewable Energy Laboratory of the United States) were analyzed, referring to hybrid configurations without energy storage and using solar and wind resources, whose complementarity is present at the site of the simulations. This complementarity of solar and wind resources was also analyzed. Photovoltaic (PV), Heliothermal with parabolic troughs (CSP/PTC), Heliothermal with central tower and heliostats (CT) and Wind (EO) with horizontal axis turbines were simulated. From the results obtained, it was possible to observe that hybrid configurations presented much more linear power curves than those with a single type of technology, similar to what is obtained when using energy storage, thermal or battery. The configurations with a predominance of wind generation stood out for the greater volume of energy generated, higher capacity factor, higher overall efficiency, higher NPV and lower LCOE in relation to the others. The benefit of the complementarity of meteorological resources was more significant in the configurations with predominance of solar resources. From an economic and performance point of view, among the configurations that use solar resources, the one that best integrated with wind power was photovoltaic.
