1. Modeling of the trajectory of ice thrown from a wind turbine
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : 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.

2. 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 ekosystemvetenskapSammanfattning : 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.

3. Ride through Capability of medium-sized Gas Turbine Generators : Modelling and Simulation of Low Voltage Ride through Capability of Siemens Energy's medium-sized GTG and Low Voltage Ride through Grid Codes requirements at point of connection
Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronikSammanfattning : In order to reduce emissions and achieve sustainable energy systems, renewable energy is increasingly being integrated into the power grid. However, the integration of renewable energy into the grid poses several challenges, including maintaining a stable power supply under changing and unpredictable conditions. LÄS MER
4. Damping of sub-synchronous control interactions with a STATCOM : Wind farms & series compensated power lines
Master-uppsats, Uppsala universitet/Institutionen för elektroteknikSammanfattning : The power converter is one of the key components in power system applications such as high voltage direct current (HVDC) systems and the grid connection of intermittent sources such as wind and solar power. However, the increased penetration of converter-based generation introduces challenges, such as sub-synchronous interaction between the converter control system and the grid. LÄS MER
5. Hållfasthetsanalys av en optimerad vikbar konstruktion för vindkraftverk
Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Miljöfrågan tar mer och mer plats i dagens debatt och efterfrågan på förnybar energi är högre än någonsin. Vindkraftverk är ett möjligt svar på dagens klimatproblem och denna rapport kommer undersöka hur vindkraftverk kan optimeras. LÄS MER
