  1. 1. INVESTIGATING THE FEASIBILITY AND THE POLICIES FOR WIND POWER REPOWERING IN SWEDISH MUNICIPALITIES

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Samuel Roško; [2023]
    Nyckelord :wind power; full repowering; onshore wind; economic feasibility; financial viability; WindPro; municipal policy; comprehensive plans; Swedish municipalities; case studies; AEP; noise; shadow;

    Sammanfattning : Transitioning to a low-carbon energy system includes deploying renewables such as wind power, which has been installed in Sweden since the 1980s. After a 20 to 25-year lifetime, a wind turbine´s end-of-life options come into play, therefore many of the turbines deployed in Sweden prior to 2011 will reach this mark by 2035. LÄS MER

  3. 2. Optimering av en flytande vindkraftspark

    Kandidat-uppsats, Uppsala universitet/Materialteori

    Författare :Mattias Blavier; Elin Granath; Emelie Jin; Elin Johansson; Axel Svensson; Kristina Thylin; [2023]
    Nyckelord :Vindkraft; flytande vindkraft; simulering; modellering; optimering; AEP; LCOE;

    Sammanfattning : This paper presents a study on the optimization of floating offshore wind farms. The aim of this study is mainly to create a tool that can help determine the most profitable layout option for the floating offshore wind power company Windeed. LÄS MER

  4. 3. Optimization of Grid Connection Capacity for Onshore Wind Farms

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Patrik Wall; [2022]
    Nyckelord :icing; optimization; grid capacity; full-performance; power curve; Monte Carlo; Markov chain;

    Sammanfattning : This thesis investigates if the profitability of a wind farm can be increased by reducing itscontracted grid capacity. Two years of SCADA data is cleaned from non- and partialperformance which is used to estimate a wake reduced annual power time series. LÄS MER

  5. 4. Stepdown-omvandlare med låg tomgångsförlust

    Kandidat-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :David Smedberg; [2020]
    Nyckelord :;

    Sammanfattning : A power supply unit with very low standby losses has been constructed. A reference design from Texas Instrument was used as a comparison and starting point. A choice between optimizing the existing reference design or creating a new power supply was made. The losses in the reference design was located to be due to high switching frequency. LÄS MER

  7. 5. When a natural disaster occurs during a conflict – Catalyst or obstacle for peace? : A comparative case study of the insurgency in Aceh, Indonesia and the Sri Lankan civil war in relation to the Indian Ocean tsunami in 2004

    Magister-uppsats, Uppsala universitet/Teologiska institutionen

    Författare :Joanne van der Vlist; [2020]
    Nyckelord :Indian Ocean tsunami 2004; Aceh; Indonesia; Free Aceh Movement; Gerakan Aceh Merdeka GAM ; Sri Lanka; Liberation Tigers of Tamil Eelam LTTE ; Tamil Tigers; civil war; peace; rational choice theory RCT ;

    Sammanfattning : Superficial information of the civil wars in Aceh, Indonesia and Sri Lanka creates the idea that both conflicts were in similar situations when they were hit by the Indian Ocean tsunami in 2004. It thus seems surprising that in the wake of the tsunami, the Free Aceh Movement and the Government of Indonesia signed a peace agreement, while the Liberation Tigers of Tamil Eelam and the Government of Sri Lanka returned to war.
