The thesis examines which energy production methods are suitable together with seasonal storage of energy at UiT the arctic university of Norway in Narvik. Nordkraft has provided the subject which has been examined. The location of UiT Narvik together with its areas and storage volumes have been examined for what power production methods and energy storage methods are suitable for this location. ...

Inverter-based resources (IBRs), such as solar and wind power are gaining popularity because of their increasing acceptance, environmental benefits and decreasing costs. However, their integration into power systems can lead to significant impacts on system inertia and frequency stability, which are crucial for maintaining the reliability of the power grid. In traditional power systems, the synchronous ...

Denne oppgaven presenterer en studie om modellering og analyse av lengre kraftkabler på generatorsiden av en enhetstransformator i et generisk kraftsystem. Studien fokuserer på det teoretiske rammeverket som er nødvendig for å forstå problemet. De teoretiske delene inkluderer grunnleggende elektriske sannheter og deres effekter på hovedkomponentene i et kraftsystem. Den gjenværende teorien ...

Reliable, consistent and very high data rate mobile communication will become especially important for future services such as, among other things, future emergency communication needs. MmWave technology provides the needed capacity, however, lacks the reliability due to the abrupt capacity changes any one path experiences. Intelligently making use of varying numbers of available mmWave paths, ...

Underwater wireless power transfer (UWPT) has become an area of great interest due to the advancement of autonomous underwater vehicles (AUVs) and electic boats. This paper seeks to investigate the variation of the coupling coefficient and power transfer in air versus in seawater. The design is based on a class E converter as it can achieve soft-switching inherently. I made the transmitter and ...

In this thesis a version of the Kundur two-area model has been developed for Simulink and real time simulator software and hardware from OPAL-RT. This model should be used for testing the rotor angle oscillations load variations create. A review of the different control elements found in basic power systems has been reviewed and implemented. The main component that will be manipulated in the model ...

In today’s world, electrical energy is a necessity. The dependency on electricity is increasing day by day which caused the system to work under a stress state close to stability limits and disturbances. An efficient power system supplying electrical energy must be reliable, stable, secure, and reasonable to meet consumer needs. The power demand depends on several factors and weather is one of the ...

The inevitable growing demand for electrical power, depleting sources of conventional power generation, and world wide concern about global warming are major factors to boost the trend of renewable integration in grids. This rising trend is causing many technical and operational challenges where one of the most prominent problem is the overvoltage caused by distributed generation units, interfaced ...

"Designing an all-electric battery vessel, knowledge of the dynamic performance of the electrical propulsion plant becomes crucial to produce adequate estimates of needed battery capacity. An energy management system is to control the on-board power flow and ensure energy efficient operation of the vessel. This thesis presents a solution for dynamic simulation of an all-electric battery vessel based ...
