    • Undersjøiske skred i Balsfjorden, Nord-Norge: egenskaper og sammensetning 

      Iversen, Vera (Master thesis; Mastergradsoppgave, 2014-06-02)
      Batymetridata, høyoppløselige seismisk data samt en sedimentkjerne fra indre Balsfjorden, Troms, nord-Norge, har blitt analysert for å undersøke sedimentasjonsprosesser i løpet av Holocen, med spesiell fokus på undersjøiske rasavsetninger. Hovedvekt av denne oppgaven ligger på analyse av den 8,67 m lange sedimentkjernen JM11-001-PC. Dette inkluderte beskrivelse av sedimentoverflate og røntgen ...

    • Utilizing batteries in the Norwegian distribution grid 

      Eidissen, Magnus (Master thesis; Mastergradsoppgave, 2023-06-04)
      Recent research indicates that photovoltaic (PV) induced overvoltage can occur in high PVpenetration low voltage distribution networks, due to reverse power flow from power injected to the grid. Since January 2020, the number of PV installations in Norway has seen a 2.7-fold increase in a rising trend. Simultaneously there have been several reports of grid-overvoltage and PV curtailment in the ...

    • Vurdering av snøskredfare og sikring for vegene E6 i Langfjorden og Fv 882 til Øksfjord i Finnmark fylke 

      Karlsen, Espen (Master thesis; Mastergradsoppgave, 2013-05-27)
      Stengte veger på grunn av snøskred eller fare for snøskred utgjør ca. 55% av all registrert vegstengning langs norske veger. En økende sammenknytning av landsdelene stiller stadig større krav til framkommelighet og fleksibilitet. Tidligere har det vært opp til hvert enkelt vegprosjekt å bestemme en akseptabel risiko for skredhendelser på veg. Statens Vegvesen ønsker å utvikle en modell for risikoaksept ...

    • Wet snow detection by C-band SAR in avalanche forecasting 

      Hopsø, Ingrid Strømsvik (Master thesis; Mastergradsoppgave, 2013-12-15)
      Avalanches usually occur in steep, snow-covered mountain sides under special conditions. The stability of the snowpack depends, among other things, on the melting and freezing of the snowpack. If a snow covered area has not undergone a melt/freeze-process, it could potentially be unstable due to depth hoar or buried layers of frost, and therefore pose an avalanche risk if the area is located at a ...

    • Wind at Northern Senja: Use of numerical weather prediction models for wind resource assessment 

      Hansen, Gjøran Emil (Master thesis; Mastergradsoppgave, 2020-12-15)
      Wind resource assessment for establishing decentralized power production in remote and complex areas, is challenging due to a lack of observational data. To overcome this problem, Numerical Weather Prediction (NWP) models can be used to provide data where no observations exist. This thesis uses NWP models to do a wind resource assessment at northern Senja. The power grid in the area is prone to ...

    • Wind energy and economic assessment of a wind farm at Senja 

      Ørjavik, Ola Wang (Master thesis; Mastergradsoppgave, 2022-05-31)
      In order to deliver on the emission cuts in the Paris Agreement, additional renewable energy production is required to cover the rising energy demand. This thesis assesses the wind resources, energy production potential and the economic sustainability of a new potential wind farm, located at Senja island in northern Norway. The aim of this thesis is to decide if a new wind farm at Senja is an ...

    • Wind power forecasting as input to day-ahead trading strategies for wind in complex terrain 

      Svane, Julie Therese (Master thesis; Mastergradsoppgave, 2022-06-01)
      Giving the increasing penetration of intermittent wind power in the liberalized electricity market, wind power forecasting (WPF) is a topic of growing importance [Kariniotakis, 2017]. The number of papers on the field WPF evaluating the statistical performance has increased rapidly, while only a proportion of the former studies focus on the economic benefit of WPF. In this study we have answered how ...

    • Wind Power Prediction with Machine Learning Methods in Complex Terrain Areas 

      Sæther, Brynhild Bentsen (Master thesis; Mastergradsoppgave, 2021-06-29)
      The increasing amount of intermittant wind energy sources connected to the power grid present several challenges in balancing the power network. Accurate prediction of wind power production is identified as one of the most important measures for balancing the power network while maintaining a sustainable integration of wind power in the power grid. However, the volatile nature of wind makes wind ...

    • Wind resource assessment and siting for the expansion of Fakken wind park 

      Bjugg, Martine (Master thesis; Mastergradsoppgave, 2023-05-31)
      Norway is anticipated to experience an energy deficit in the coming years, and one solution to address this issue is the implementation of new renewable energy sources. To mitigate the projected energy deficit, increased energy production is required. With its considerable wind potential, the country offers ample opportunities for wind energy development. Consequently, there is a growing demand for ...

    • Wind resource assessment using weather research and forecasting model. A case study of the wind resources at Havøygavlen wind farm 

      Fossem, Anders Aarhuus (Master thesis; Mastergradsoppgave, 2019-12-13)
      The need for energy increases globally due to rapid expansion of population and prosperity. To meet this demand while decreasing carbon emission and eventually transition out fossil fuel, efficient utilization of wind power is prominent. This study evaluates the performance of the Weather Research and Forecast model (WRF) with respect to wind speed and wind direction. The area of the study is ...
