Influencia de la estabilidad atmosférica en la producción energética de los aerogeneradores marinos

Abstract

At present, the high production wind energy, with 591,549 MW installed, is the second renewable with the greatest worldwide implantation and contributes in an outstanding way in the energy mix of some countries. Likewise, offshore wind energy has experienced rapid growth in recent years, with the implementation of new offshore wind farms with increasing powers, reaching an accumulated capacity of 23,140 MW at the end of 2018 (GWEC, 2019). The immense untapped wind potential of large marine areas around the world, make necessary a reliable method of predicting the wind resource, valid for any latitude, capable of determining the energy viability of new offshore wind farms. The knowledge of the interactions in the marine atmospheric boundary layer, identifying the boundary conditions, will help us achieve this purpose. The objective of this communication is to characterize the influence of atmospheric stability, in open sea conditions, on the production of energy from marine wind turbines. For this, the logarithmic profile of the wind, the theory of similarity for neutral atmosphere conditions and a more general expression that includes a stability function for unstable and stable conditions will be considered.
