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 optimization problem that is solved by the harmony search (HS) algorithm. In this paper, two distinct methods of full and partial optimal cable sizing are considered to comprehensively assess the optimal interconnection layout of OWFs. Furthermore, various shipping and burying costs as well as various WTs power ratings are considered in order to investigate their impact on the optimal electrical interconnection system. The optimal electrical interconnection design obtained by the HS algorithm corresponds to a lower cost that together with the technological developments can help policy makers increase the use of offshore wind energy as a feasible unlimited renewable resource in their energy production portfolios.

Numerical simulations of wind turbine wake interactions using actuator line and les models
Önel, Hüseyin Can; Tuncer, İsmail Hakkı; Department of Aerospace Engineering (2019)
Wind is one of the most promising renewable energy resources of the future. After years of optimization studies, Horizontal Axis Wind Turbines shine out as the most efficient type and have been the only model used in large scale commercial wind farms. Layout planning plays an important role in getting the most power out of a wind farm as much as turbine blade design. Most important parameter in this planning phase is the inevitable wake generated by rotors and its impact on other wind turbines which results...

Wind energy is considered one of the cleanest and most sustainable resources among renewable energy sources. However, several negative environmental impacts can be observed, unless suitable sites are selected for the establishment of wind farms. The aim of this study is to determine the change in the soil organic carbon (SOC) stock resulting from land cover changes that were caused by wind farm establishments in the Karaburun peninsula. Within the scope of the study, remote sensing and geographic informatio...
Coupled aerodynamic and hydrodynamic analyses of upscaled floating offshore wind turbines
Juanda Putra, Muhammad; Oğuz, Elif; Sezer Uzol, Nilay (2022-09-26)
As one of the widely used renewable energy sources, wind energy is expected to lead the energy market. A recent trend is to develop bigger wind turbines since upscaled wind turbines’ rotor size increases power production and reduces a significant amount of maintenance cost of a wind warm. Especially, due to the dimension of roads used in transportation of the turbine blades and components, there are strict limitations for design of onshore wind turbines. This study aims to investigate aerodynamic and hydrod...
Design of a modular, axial-flux direct drive permanent magnet generator for wind turbines
Başkaya, Aydın; Keysan, Ozan; Department of Electrical and Electronics Engineering (2018)
Wind energy technology is becoming more important issue in terms of renewable energy applications. Theoretical maximum of wind energy utilization is known (which is predetermined by Betz as 59%) and generally imperfections in blade manufacture reduce the actual energy yield of the turbine less than the useable energy. Therefore, maximum energy yield from generator topology is desired. According to fault statistics of wind turbines, most of the cases are related to gearbox failures. Mechanical losses and hea...
Investigations of upscaling effects for aerodynamic design of large wind turbine rotors by using BEM theory and optimization
Kesikbaş, Ozan.; Sezer Uzol, Nilay; Department of Aerospace Engineering (2019)
In recent years, wind power has become one of the most preferred and accepted renewable energy sources. However, there are still design challenges of new wind turbines especially upscaling problems as the size of rotor blades gets larger and larger. The main objective of this research is to understand scaling effects on wind turbine design by investigating and developing new design and scaling methodologies. For the design studies, the 5 MW NREL wind turbine is used as the baseline rotor. For the upscaling ...
