    Abstract : There has recently been an increased interest in hydrogen, both as a solution for seasonal energy storage but also for implementations in various industries and as fuel for vehicles. The transition to a society less dependent on fossil fuels highlights the need for new solutions where hydrogen is predicted to play a key role. READ MORE

  2. 2. The Changing Character of Mars’ Bow Shock

    University essay from Umeå universitet/Institutionen för fysik

    Author : Sara Östman; [2021]
    Keywords : Bow shock; Space plasma physics; Mars;

    Abstract : The aim of the project is to investigate the characteristics and causes of two different types of bow shocks at Mars. We define Type 1 as an undefined, drawn out ramp, and Type 2 as a shorter duration ramp that has clearer characteristics and behaves more like a step increase in the magnetic field. READ MORE

  3. 3. 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. 4. ONSHORE WIND FARM REPOWERING ALTERNATIVE SCENARIOS AND COST ASSESSMENT

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Hassan Al Hamed; [2021]
    Keywords : Wind power; repowering; feasibility study.;

    Abstract : Many reasons to consider extending the useful time of ageing wind farms. Like to take advantage of it being located in a good wind source, besides existing infrastructure, etc. Repowering can be an appropriate option for the ageing wind farm that suffering less yield energy and increment of cost of operation and maintenance.

    Abstract : Due to the increase of rotor size in horizontal axis wind turbine (HAWT) during the past 25 years in order to achieve higher power output, all wind turbine components and blades in particular, have to withstand higher structural loads. This upscalingproblem could be solved by applying technologies capable of reducing aerodynamic loads the rotor has to withstand, either with passive or active control solutions. READ MORE
