  1. 1. Uncertainty quantification for offshore wind turbines

    University essay from KTH/Matematik (Avd.)

    Author : Ziming Wang; [2022]
    Keywords : wind energy; uncertainty propagation; polynomial chaos; Rosenblatt transformation; quadrature; regression; vindenergi; osäkerhetsutbredning; polynomkaos; Rosenblatt transformation; kvadratur; regression;

    Abstract : Wind energy is a field with a large number of uncertainties. The random nature of the weather conditions, including wind speed, wind direction, and turbulence intensity, influences the energy output and the structural safety of a wind farm, making its performance fluctuate and difficult to predict.

  3. 2. Inclusion of Wind Turbines into Frequency Support Services : Exploring frequency stability issues and comparing regulation power market products

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Oskar Andersson; [2021]
    Keywords : Frequency Containment Reserve; Frequency Restoration Reserve; Fast Frequency Restoration; Synthetic Inertia; Variable Speed Wind Turbine;

    Abstract : There is a trend in Sweden towards increasing the electricity production from renewable energy sources in the electric grid. The increased share of renewables could be seen as essential for Sweden to be able to meet the obligated climate goals. READ MORE

  4. 3. Integrating Wind Power into The Electric Grid : Predictive Current Control Implementation

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Ahmad Badran; [2020]
    Keywords : Model predictive control; Wind turbine; Predictive current control; Inverter; Simulink; Active power; Reactive power.;

    Abstract : The increasing penetration of wind power into the power system dominated by variable-speed wind turbines among the installed wind turbines will require further development of control methods. Power electronic converters are widely used to improve power quality in conjunction with the integration of variable speed wind turbines into the grid. READ MORE

  5. 4. Automatic wind turbine operation analysis through neural networks

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Alexander Boley; [2017]
    Keywords : SCADA; artificial neural network; wind turbine; data analysis; statistical analysis; O M; MATLAB; SCADA; artificiella nätverk; vindkraft; dataanalys; statistisk analys; drift och underhåll; MATLAB;

    Abstract : This master thesis handles the development of an automatic benchmarking program for wind turbines and the thesis works as the theoretical basis for this program. The program is created at the request of the power company OX2 who wanted this potential to be investigated. The mission given by the company is to: 1. READ MORE

  6. 5. Hydrostatic transmission in wind turbines : Development of test platform

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Joel Rapp; Jonatan Turesson; [2015]
    Keywords : Wind turbine; Hydrostatic transmission; Test platform; Maximum power tracking; Hydraulic system;

    Abstract : This master thesis project is a part of a larger project with the goal of develop-ing a drivetrain, utilizing a hydrostatic transmission, for horizontal axis mid-sizewind turbines. Some of the benefits from using a hydrostatic transmission are thata variable speed operation is possible without the use of a frequency converter,the generator may be placed on the ground and thus reduce weight in the nacelleand also using hydraulic components can increase lifetime and robustness of thesystem.
