This study focuses on finding the optimum hub height (i.e., tower height) distributions for two interacting on-shore wind farms that are located on relatively complex terrain. Different optimization scenarios are studied, which take into account both the wind farm power output and the relevant cost variations due to changing hub heights. Simulations are performed using the Flow Redirection and Induction in Steady State (FLORIS) framework, which is modified to represent significant variations in hub height levels due to elevation differences, hence partial wake interactions that are occurring as a consequence, are more realistically represented. Optimization is based on a systematic procedure that includes introducing definitions of overall evaluation criterion parameters for objective setting and generation of design of experiments tables and related data via FLORIS simulations to properly cover the design space. A Pareto analysis of generated data to find the most influential parameters is then performed, and response surfaces are generated to represent these variations, which are, in turn, used for Monte Carlo based simulations to determine the optimized hub height distributions. Overall, the optimized results show a reasonable increase can be achieved in wind farm power output levels, while total tower height levels (hence related cost levels) are either not changing or in some cases even getting reduced for the wind farms in consideration.

Inter Farm Interactions and Hub Height Optimization for Onshore Wind Farms
Kütükcü, Gökay; Uzol, Oğuz; Department of Aerospace Engineering (2022-9)
This thesis presents the results of an investigation that focuses on finding the optimum tower height distributions for two interacting on-shore wind farms that are located on a complex terrain. Four different optimization scenarios are studied based on two different definitions of objective functions, which take into account both the power production capacity and the relevant cost variations due to changing hub heights. The study is based on simulations using the FLORIS framework, which is modified such th...
3-D basin geometry model to determine the site effects based on geophysical and geotechnical data: Case study at near-field and high seismicity area of Gölyaka, Düzce, Turkey.
Yousefibavil, Karim; Koçkar, Mustafa Kerem; Akgün, Haluk (2018-04-13)
The near-field and high seismicity of the area makes the determination of the bedrock geometry more complex and pioneers the studies of site response analysis in account for a seismic hazard assessment. Without a good model of basin structure, any powerful calculation method would lack a well-developed basin response. The study has been conducted in the Gölyaka basin that uniquely falls within the bifurcated near-field section of the North Anatolian Fault System. The surface rupture of the 1999 Earthquakes ...
Vector-Valued Probabilistic Seismic Hazard Assessment for the Effects of Vertical Ground Motions on the Seismic Response of Highway Bridges
Gülerce, Zeynep (SAGE Publications, 2010-11-01)
The vertical ground motion component is disregarded in the design of ordinary highway bridges in California, except for the bridges located in high seismic zones (sites with design horizontal peak ground acceleration greater than 0.6 g). The influence of vertical ground motion on the seismic response of single-bent, two-span highway bridges designed according to Caltrans Seismic Design Code (SDC-2006) is evaluated. A probabilistic seismic hazard framework is used to address the probability of exceeding the ...
Analysis of long term trends of precipitation estimates acquired using radar network in Turkey
Yılmaz, Mustafa Tuğrul; Yücel, İsmail; Yılmaz, Koray Kamil (null; 2016-04-17)
Precipitation estimates, a vital input in many hydrological and agricultural studies, can be obtained using many different platforms (ground station-, radar-, model-, satellite-based). Satellite- and model-based estimates are spatially continuous datasets, however they lack the high resolution information many applications often require. Station-based values are actual precipitation observations, however they suffer from their nature that they are point data. These datasets may be interpolated however such ...
Micro-siting of wind turbines using navier-stokes solutions coupled with a numerical weather prediction model
Ahmet, Gökhan; Tuncer, İsmail Hakkı; Department of Aerospace Engineering (2014)
High resolution atmospheric flow solutions are obtained with an in-house, parallelized 3 dimensional Navier-Stokes solver, HYP3D coupled with a meso-scale meteorological weather prediction software, WRF, and the wind potential of a specified terrain is assessed based on long term atmospheric flow solutions. Body-fitted grids are employed to discretize the complex terrain of interest in HYP3D. In the study, high resolution (1.5 arcsec) topographical data is used to discretize the specified terrain. In HYP3D ...
