Effects of complementarity in time between wind and water resources on the performance of a wind hydro hybrid system in northeastern Brazil / Efeitos da complementaridade no tempo entre os recursos eólicos e hídricos no desempenho de um sistema híbrido eólico no nordeste do Brasil

Abstract

growing demand with higher quality requirements. At the same time, our world, largely based on non-renewables, see these resources approaching scarcity. In this context, it is important to get energy supplies from renewable resources and seek ways to leverage these resources as well as possible. The complementarity between energy resources can be a way to make better use of available resources, enabling a greater supply of energy and facilitating the management of devices for energy storage. This paper presents preliminary results of the identification of complementarity between water and wind resources in a portion of northeastern Brazil. Further, this paper presents simulation results for a hydro wind hybrid system showing the effects of complementarity. Located on a site with resources without complementarity, the insertion of an artificial lag in the data shows how the system would be feasible. The effects of complementarity for the benefit of the feasibility of a hybrid system will prove more effective in conditions of scarce energy resources. In smaller systems, can be taken into account complementarity in time. In larger systems, may also be considered complementarity in space.
