Use of wind power for energy generation in urban areas is gaining importance considering the energy consumption and environmental impact behaviors of built environments. Therefore, assessment of urban wind resource is crucial. The study of air flows in cities is also related to other concerns as natural ventilation, air contamination and pedestrian comfort. Two of primary research topics proposed in feasibility studies for urban wind energy are improvement on the understanding of urban wind flows with developed methods; also, an enhanced knowledge on the interaction of urban geometry with air movements. Related literature points out that there is a need for better communication between disciplines concerned with research and design. As an interface which help both sides to configure their studies, algorithm aided design tools may offer opportunities. The aim of this study is to propose a framework for parameterization of built forms for wind related studies with the use of parametric model algorithms by visual programming interfaces. Thus, a faster and diversified production of sample models can be provided by changing values of geometric variables. An example model within this framework was developed. To achieve this, a literature survey was conducted with a focus on extracting and aggregating possible shape attributes, architectural form and urban formation parameters. UML diagrams were used before translating parameters into the interface of Dynamo software. Simple flow simulations made on samples derived from parametric models. By comparing results with parameter sensitivity analysis, influences of the parameters and relevancy of the example model were observed.

Stochastic modelling of wind energy generation Alişar, İbrahim; Sevaioğlu, Osman; Department of Electrical and Electronics Engineering (2012) In this thesis work, electricty generation modeling of the wind energy -one type of the renewable energy sources- is studied. The wind energy characteristics and the distribution of wind speed in a specific region is also examined. In addition, the power curves of the wind turbines are introduced and the relationship between the wind speed and wind power is explained. The generation characteristics of the wind turbines from various types of producers are also investigated. In this study, the main wind power...
Determination of wind power potential and optimal wind power plant locations in Turkey Çetinay, Hale; Güven, Ali Nezih; Tör, Osman Bülent; Department of Electrical and Electronics Engineering (2014) Due to increased environmental concerns, utilization of the renewable energy, especially the wind power, gains importance. Like developed countries which have set their renewable energy targets for the long term integration, Turkish government has also set the goal as 20 GW of total wind power installed capacity in 2023. In this thesis, the wind power potential in Turkey is analyzed and different cases are studied to determine optimal locations for wind power plant establishment. In order to determine the w...
Data mining-based power generation forecast at wind power plants Özkan, Mehmet Barış; Karagöz, Pınar; Department of Computer Engineering (2014) As a result of rapid depletion of non-renewable energy resources, the importance of the e efficient utilization of renewable energy sources has increased all over the world and in our country in recent years. Wind has an important role in renewable energy sources with its high potential. However, compared to other renewable energy sources, wind has a spatial and temporal discontinuity characteristic so there is a need for estimating and planning of wind power generation. Wind Power Plants (WPPs) inform thei...
Rethinking wind energy in its social context: conflicting perspectives and planning problems – the Karaburun experience Özçam, Zeynep; Pınarcıoğlu, Mehmet Melih; Department of City and Regional Planning (2016) As a result of global concerns about energy related environmental problems, the use of renewable energy resources has gained great importance. The renewables are widely recognized as an effective tool for limiting energy related emissions and a fundamental component of sustainable development. Among these, especially wind energy has considerable involvement. Due to this, major national policies intend to support wind energy and wind energy installations have also started to grow with an expanding rate. Like...
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...
