Extensive increase of variable production renewable power from wind and solar in Northern Europe has ... -
Forecasting Wind Turbine Production Losses due to Icing
(Master thesis; Mastergradsoppgave, 2023-05-31)In order for wind energy producers to avoid the extra costs of inaccurate production estimates for the day-ahead energy market, precise forecasts of power production during the next day have to be made. For renewables such as wind energy, power production is particularly difficult to predict as it depends on the fluctuating wind speed. In addition, forecasting the power production in cold climates ... -
Comparative performance analysis of two high-latitude solar photovoltaic systems
(Master thesis; Mastergradsoppgave, 2023-05-30)The global energy demand and the urgency to limit greenhouse gas emissions require a transition to cleaner energy sources.
