  1. 1. Weight Optimization of Vertical-Axis Wind Turbine Blades constructed in Swedish Fossil Free Steel : With respect to fatigue life time

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Johannes Hall; Albin Larsson; [2023]
    Keywords : VAWT; Wind Turbine Blade; SSAB; Fossil-Free; Weight Optimization; Topology Optimization; Sizing Optimization; NACA 0018; STRENX 1300; Abaqus; Tosca Structure; VAWT; Vindturbinblad; SSAB; Fossilfritt; Viktoptimering; Topologioptimering; Size-Optimering; NACA 0018; STRENX 1300; Abaqus; Tosca Structure;

    Abstract : Wind turbines have been utilized for centuries to harness energy from the wind. Commercial wind turbine blades are typically made from composite materials, which are difficult to recycle, leading to blades ending up in landfills at the end of their lifecycle. Additionally, these materials contribute to microplastic pollution. READ MORE

  3. 2. Pilot Study: Test Rig for Self-lubricating Kaplan Runner Bearings

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Bhairav Khadke; [2023]
    Keywords : Hydropower; Kaplan turbine; Self-lubricating bearing Test rig. Hydropower; Kaplan turbine; Self-lubricating bearing Test rig.; Vattenkraft; Kaplanturbin; Självsmörjande lager Testrigg.;

    Abstract : Hydropower has a relatively small impact on the climate and contributes to almost half of Sweden’s electricity production. Vattenfall own and operate roughly 125 large scale hydro power units of which about half utilizes a Kaplan turbine. READ MORE

  4. 3. Grey-box Modeling of Hydropower Plants for Improved Frequency Regulation : Evaluation of Double-Regulated Hydropower Turbines for Fulfillment of the New FCR-requirements

    University essay from Uppsala universitet/Elektricitetslära

    Author : Karolina Engström; Rebecca Waldenfjord; [2023]
    Keywords : Double-regulated hydroturbines; Grey-box modeling; FCR-requriements; Frequency contaminent reserve; Hydropower modeling; Dynamic stability; Dynamic performance;

    Abstract : Over the last decades, the frequency on the Nordic electrical power grid has deteriorated. Therefore, new stricter requirements are developed for the hydropower delivering regulating active power on the Frequency Containment Reserve market (FCR). READ MORE

  5. 4. Financing green energy projects : Funding possibilities, challange for change, and the integration of the private sector

    University essay from Jönköping University

    Author : Rickard Djerf; Solveig Edblad; [2023]
    Keywords : Energy source; Wind turbine; Economic association; Permit process; Renewable support scheme; Subvention; Green finance; Green energy; Energikälla; Vindkraftverk; Ekonomisk förening; Tillståndsprocess; Förnybara stödsystem; Subventioner; Grön finansiering; Grön energi;

    Abstract : The world’s energy structure today relies 80 % on fossil fuels, contributing to rising temperatures and a changing climate. Society is built upon heavy energy usage and consumption is forecasted to increase rather than decrease. READ MORE

  6. 5. 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.
