Offshore wind farm site selection for Aegean and Mediterranean Sea, Turkey

Yıldız, Hatice Kübra
This thesis was focused on investigating potential sites in the Aegean and Mediterranean Sea for offshore wind turbines considering a number of criteria such as water depth, wind speed, grid connectivity, etc. Prior to that, all major floating offshore wind turbine installations in Europe and across the World were reviewed. The current status of the offshore wind industry in terms of technology and supporting mechanisms were summarized. Following this, potential sites were mapped using collected data from a wide range of sources and analyzed using the Geographical Information System (GIS) program. For potential sites, a detailed GIS analyses were carried out considering buffer zones and restricted areas. Among the potential sites, the most suitable sites were selected. Then, turbine layout was prepared for the most suitable sites, and potential of wind power plants was roughly estimated. Lastly, grid connection was prepared for the most suitable sites; then, onshore and offshore cable lengths were calculated.


Experimental Study of a TLP Offshore Floating Wind Turbine
Oğuz, Elif; Clelland, David; İncecik, Atilla; Dai, Saishuai; López, Juan Amate; Sánchez, Gustavo (null; 2016-07-18)
Tank testing in a wind and wave environment is a key part of the design process for the development of an offshore floating wind turbine. The current paper describes an extensive experiment campaign carried out at the Kelvin Hydrodynamics Laboratory at the University of Strathclyde to determine the hydrodynamic performance of the Iberdrola TLPWIND offshore floating wind turbine with the NREL 5MW reference turbine over a range of environmental conditions. Tests were carried out for 70m water depth and the de...
Hydrodynamic analysis of floating offshore wind turbine concepts: a case study in Black Sea
Yıldırım, Büşra; Oğuz, Elif; Department of Civil Engineering (2022-10-19)
In the literature, well-validated hydrodynamic programs such as WAMIT are used to analyze the hydrodynamics of floating offshore wind turbines (FOWTs). In this thesis, potential use of an opensource hydrodynamic solver for the hydrodynamic modeling of FOWTs is investigated using HAMS. For this purpose, hydrodynamic coefficients obtained from HAMS are compared to the first-order hydrodynamic solution of AQWA and WAMIT. The hydrodynamic model of three FOWT concepts, such as OO-Star, Nautilus, and CENTEC...
Geothermal energy potential and utilization in Turkey
Taşdemiroğlu, Ersoy (Elsevier BV, 1988-3)
The regional distribution of the geothermal energy potential in Turkey, recent surveys, and utilization areas are described. The present and future roles of geothermal energy and their economic aspects are discussed. The implications of geothermal energy exploration and utilization are noted. Recommendations are made to expand geothermal-energy development.
Experimental study on power curtailment of three in-line turbines
Bartl, Jan; Ostovan, Yasar; Uzol, Oğuz; Saetran, Lars (Elsevier BV; Elsevier BV; 2017-01-20)
A dataset of wind tunnel power and wake flow measurements on a setup of three aligned model wind turbines is presented. The power outputs of the three turbines are in good agreement with measurements from a full-scale wind farm of similar inter-turbine spacing. A comparison of the wake flow behind the first row and the second row shows a significantly higher mean velocity loss behind the second row justifying a further power drop from the second to the third row turbine. Curtailing the front row turbine to ...
Simultaneous optimization of electrical interconnection configuration and cable sizing in offshore wind farms
Fahrioğlu, Murat; Sedighi, Mohsen; Moradzadeh, Mohammad; Kukrer, Osman (Springer Science and Business Media LLC, 2018-1-18)
Offshore wind farm (OWF) is the largest renewable energy resource. The electrical interconnection cost of OWFs is a considerable fraction of the overall design cost of the farm. In order to minimize the investment and operational costs, this paper proposes an optimization formulation to find the optimal electrical interconnection configuration of wind turbines (WTs), and the optimal cable sizing simultaneously. This simultaneous minimization of total trenching length and cable dimensions creates a complex o...
