Sensitivity analysis in key parameters related to wind power production
(Master thesis, 2021-06-01) -
SFY: A free-drifting wave buoy for measuring surf waves
(Master thesis, 2023-06-01)Breaking waves have been studied for over a century. Still, there is an insufficient understanding of wave breaking due to limited in situ data. The high variability and the energetic environment in the surf zone makes it ... -
Short-term hydropower scheduling at watercourses with flooding risks
(Master thesis, 2022-06-01) -
Smart operations for low-emission maintenance vessels at offshore wind farms
(Master thesis, 2024-06-03)This thesis investigates the efficiency of maintenance operations for offshore wind farms (OWFs) using mathematical programming. The aim is to find cost-effective solutions focusing on implementing hybrid battery technology ... -
Spenningsetting av transformator: Innkoblingsstrøm og koblingsspenninger ved ulike parametere
(Master thesis, 2022-06-01)Tilfeldig innkobling eller spenningssetting av transformatorer uten last, kan føre til redusert levetid på utstyr og leveringskvalitet i kraftnettet. I tillegg til det økonomiske perspektivet og driftssikkerheten, er dette ... -
State of the Art Review of High Voltage Insulation Monitoring
(Master thesis, 2021-11-22)The devastating effects of global warming and climate change are now well understood and there is broad unity that fundamental changes are needed. This is clearly addressed in the United Nations Sustainable Development ... -
Study of Power Quality Improvement for Grid-Connected PV plant in Kilinochchi

The Atmospheric Surface Layer over Dronning Maud Land, Antarctica
(Master thesis, 2019-06-28) -
The Effect of Near-Well Heterogeneity on Spatial Distribution of Salt Precipitation During CO2 Injection
(Master thesis, 2024-06-03)The world is in need of a shift to cleaner energy, and carbon storage is expected to be an important part of the transition. Geological carbon storage is a process in which captured carbon dioxide (CO2) is injected into ... -
The Effects of Diabatic Heating on the Paradigmatic LC1 and LC2 Baroclinic Lifecycles
(Master thesis, 2023-06-01)Extratropical cyclones play a crucial role in determining mid-latitude weather, where the atmosphere is on average inducive to baroclinic instability. Literature has identified two lifecycle behaviors, one that is predominantly ... -
The importance of wind turbulence and coherence to the loads on a wind turbine blade
(Master thesis, 2019-06-25)The wind simulation method proposed by Paul S. Veers from Sandia National Laboratories has been checked for the measured wind velocities at 40m and 80m height at FINO1 platform. The Sandia method applied as it is, gives ... -
Tidal forcing and internal tide energetics around Svalbard: a numerical study
(Master thesis, 2020-06-27)The hydrostatic and linear Regional Ocean Modeling System (ROMS) is used to examine the tidal forcing and the resulting baroclinic response and energetics of internal tides generated around Svalbard in the Arctic Ocean. ... -
Transientstabilitet-implementering ved BESS for offshore mikronett i øymodus
(Master thesis, 2022-06-01)Konvensjonelle mikronett har tradisjonelt sikret spenning- og frekvensstabilitet med spinning-reserve fra roterende maskiner ved forstyrrelser i nettet. En økende andel av ikke-roterende energiproduksjon påvirker kraftsystemers ... -
Trends and internal variability in Brazilian hydropower catchments
(Master thesis, 2023-06-01)Hydropower is a major energy source in Brazil, and long-term hydropower production planning is crucial both for maintaining energy and water security in the country. The amount of water that is available to electricity ... -
