1. 1. Modeling of the trajectory of ice thrown from a wind turbine

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Elena Rocchi; [2023]
   Nyckelord :Ice thrown - Ice fall - RANS - LES - CFD - simulations - ballistic model; Technology and Engineering;

   Sammanfattning : There is a growing number of wind turbines installed in cold temperature zones as a result of the restricted space for new construction. Due to ice deposition on the turbine blades, the increasing installation of wind turbines in freezing temperature areas presents many challenges: ice accumulation increases weight, unbalances the rotor, diminishes aerodynamic efficiency, and creates safety issues.

3. 2. Simulation Model - Grid Connection of a Marine Current Power Turbine

   Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

   Författare :Muhammad Farooq Mazhar; [2023]
   Nyckelord :Power electronics; Filters; Marine-current turbine; Grid connection; Damping;

   Sammanfattning : Renewable energy is a reliable source of energy and can provide promising solution to the on-going energy crisis if harnessed properly. Some of the common energy sources in which a lot of research is invested include wind,solar, water and biofuels. LÄS MER

4. 3. Using a GIS to enable an economic, land use and energy output comparison between small wind powered turbines and large-scale wind farms: the case of Oslo, Norway.

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Colin Potter; [2023]
   Nyckelord :Geography; GIS; Wind power; Renewable energy sources; urban wind energy; urban areas; planning; vertical axis wind turbines; comparative studies; urban integrated energy systems; Oslo; Roan; Earth and Environmental Sciences;

   Sammanfattning : Responding to an identified knowledge gap, the study aims to determine if smaller wind turbines located on top of existing urban buildings are more resource efficient (land utilization and economically) than large scale wind farms. To answer this question, using a GIS, the resource efficiency of the Roan wind farm in Northern Norway was compared to a theoretical modeled installation of small-scale wind turbines on top of buildings within a 2km radius study zone in central Oslo.

5. 4. Dynamics of a CRAFT : A simulation study on a Counter Rotating vertical Axis Floating Tilting wind turbine

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

   Författare :Benjamin Hedlund Peters; Linda Goude; [2023]
   Nyckelord :wind power; counter rotating; contra rotating; offshore wind; floating wind power; vertical axis wind turbine; VAWT; renewable energy;

   Sammanfattning : In this thesis the Counter Rotating vertical Axis Floating Tilting wind turbine (CRAFT) has been explored by creating a simulation model in the program Simulink. The CRAFT prototype is a new type of wind turbine under development by World Wide Wind and Uppsala University with the aim to produce a large scale floating vertical axis wind turbine (VAWT) with two cone shaped counter rotating turbines.

7. 5. Study on feasibility of small-scale pumped hydro storage- A case study in Sweden

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Prashant Niroula; [2023]
   Nyckelord :energy storage; pumped hydropower; electricity market; investment; new technologies; feasibility; Technology and Engineering;

   Sammanfattning : The European union has been aggressively pushing forward with policies favoring renewable sources of energy. As a result, the share of intermittent renewables in the European power grid is rising and is expected to grow even more in the coming decade. The Swedish energy agency also forecast huge growth in wind power. LÄS MER
