Özet:

Wind Resource Assessment studies have become remarkable research tool to determine the possible Wind Farm locations in last two decades. Wind Farm Modeling is essential to pinpoint the wind turbines in selected region by simulating the possible layout designs of Wind Farm in advance. These studies provide improvements in cost efficiency and Annual Energy Production with the aid of Computational Fluid Dynamics (CFD). In this study, the methodologies of Wind Resource Assessment and Wind Farm Modeling are examined with a case study. The methodologies are applied to Bodrum Peninsula which is defined as a complex terrain. This topography is composed of urban, suburban, hills, different shape of islands and coastal areas. Besides these, it has various roughness classes and very high energy potential according to previous researches. WindSim program which is one of the developed research tools for this topic is utilized to perform all the necessary steps. Embedded CFD program in WindSim computes Reynolds Averaged Navier Stokes equations by using finite volume methods. Sector-wise steady state simulations are performed to predict the flow over the terrain. Annual Energy Production and wake losses are investigated for Onshore and Offshore Wind Farms. Parametric study is conducted for the variations of crosswind and downwind spacing between the wind turbines in the wind farm layouts. In parallel, AEROWIND, in-house code, is developed to perform data analysis of site information, aerodynamics of wind turbine, energy and economy analysis. This theoretical research program reduces the wind farm layout design time.
