Wind farm optimization

Yousefbeigi, Sogand
In this thesis, a mixed integer linear program is used to formulate the optimization process of a wind farm. As a start point, a grid was superimposed into the wind farm, in which grid points represent possible wind turbine locations. During the optimization process, proximity and wind interference between wind turbines were considered in order to found the power loss of the wind farm. Power loss was analyzed by using wind interference coefficient, which is a function of wind intensity interference factor (WIIF), weibull distribution and power of the wind turbines. Two different programs; Genetic Algorithm and Lingo, were used to solve the MILP optimization formula and results were compared for different cases in the conclusion part.


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 ...
Investigation of layout optimization for offshore wind farms and a case study for a region in Turkey
Kaya, Baran; Oğuz, Elif; Department of Civil Engineering (2022-2)
In this thesis, the focus was to develop an optimization tool by using mathematical layout optimization methods aiming to increase the energy capacity or reduce the cost of an offshore wind farm. For this purpose, two wind farm layout optimization (WFLO) models were developed using genetic algorithm (GA): model (a) minimizing the cost of power for variable turbine number, model (b) maximizing the power generation for fixed turbine number. Wind speed and wind direction were assumed constant. Therefore, unlik...
Dynamic modelling and simulation of a wind turbine
Altuğ, Ayşe Hazal; Yavrucuk, İlkay; Department of Aerospace Engineering (2015)
In this thesis, a dynamic model for a horizontal axis wind turbine is developed for an upwind configuration using the MATLAB/Simulink environment. Blade Element Momentum Theory is used to model the rotor. It is assumed that the rotor blades are rigid and wind speed is uniform. Aerodynamic and gravitational forces are calculated as distributed loads. Verification of the model is done by using the LMS Samtech, Samcef for Wind Turbines software. Aerodynamic properties of the blades, sectional loads and moments...
Design optimization of whiffletree systems for wind turbine blade testing
Yeniceli, Süleyman Cem; Kayran, Altan; Department of Aerospace Engineering (2014)
In this thesis, the design optimization of a whiffletree system, which is used to simulate the loads for a selected design load case by applying discrete test loads on a wind turbine blade, is performed. Firstly, distributed design loads are calculated for the selected load case by using Microsoft (MS) EXCEL. Then, the test load optimization is performed with the Solver Add-In of the MS EXCEL to find the optimum locations of the load saddles which give the best moment distribution along the blade span accor...
Investigation of inertial support limits in wind turbines and the effects on the power system stability
Duymaz, Erencan; Keysan, Ozan; Department of Electrical and Electronics Engineering (2019)
In this study, the inertial support implementation is studied for variable speed wind turbines with a full-scale power electronics. To increase the active power as desired, Machine Side Converter is modified with an additional control loop. In the first part of the thesis, active power of the wind turbine is increased to the limits and the maximum achievable active power is found out to be restricted by the wind speed. It is found that the wind turbine can increase its output power by 40% of rated power in ...
