Solvinkel optimaliserer
(Master thesis; Mastergradsoppgave, 2021-05-18)Snø og andre ting kan reflektere lys på solcellepanelene slik at de produsere mer energi. Refleksjonene kan gjøre slik at den optimale vinkelen til panelene ikke er rett mot solen. Denne rapporten går fort igjennom noen forslag til optimaliseringsalgoritmer for vinklene til solcellepanelene. Videre går den dypere inn på en algoritme som heter «test og sjekk». Kort fortalt går denne algoritmen ... -

Study and Analysis of Alternative Power Switches with Reverse-Voltage Blocking Capability
(Master thesis; Mastergradsoppgave, 2022-06-02)The current source inverters are becoming competitors of the voltage source inverters largely due to the reduced complexity, improved reliability and potentially improved efficiency. This paper describes the functionality of current source inverters and why they’re becoming increasingly popular. It also discusses about the benefits of SiC over other semiconductors and the use of SiC MOSFETS with ... -
A study of hydro and pumped storage hydropower in Northern Norway
(Master thesis; Mastergradsoppgave, 2017-06-15)"The role of renewable sources of energy in combating climate change cannot be over-emphasized. Profound measures taken especially by the European Union (EU) in reducing global rising temperatures has seen massive development of renewable sources of energy such as solar and wind. This strategic plan taken by the EU has led to the an increase in national efforts to promote further development of ... -
Study of Inter Area Oscillations Using Phasor Measurement Units
(Master thesis; Mastergradsoppgave, 2021-05-18)Low-frequency oscillations in the power system have major repercussions on power system stability and the objective of maximum power transfer. Local and global control strategies have been developed to dampen and impede these oscillations. A modern local control strategy is supplying the automatic voltage regulation (AVR) of the generator with a power system stabilizer (PSS). Modern global control ... -
