A strategic investment model for multinational transmission expansion planning - Comparing competitive and centrally planned solutions for a North Sea Offshore Grid
(Master thesis, 2018)Proper transmission expansion planning (TEP) is important to create an efficient electricity market that provide both economic and environmental benefits. However, if the expansion planner do not consider how the market ... -
A Study of Deep Sea Mining Electrical Power System Topologies
(Master thesis, 2017)Deep sea mining (DSM) is an emerging technology. The ever-increasing world-wide need for minerals in growing markets and industries of developing countries has made DSM financially reasonable. As there are few known system ... -
A Study of How Integration of Solar Photovoltaic Impact a Housing Cooperative in Norway
(Master thesis, 2020)Solenergi er den raskest voksende energikilden i verden for øyeblikket. Solenergi har i Norge tradisjonelt blitt brukt til å dekke strømbehovet til steder uten tilknytning til strømnettet, som for eksempel hytter. I løpet ... -
A Study of Internal Temperature Dependency in Norwegian Railway Transformers
(Master thesis, 2022)Trenden med økende trafikkbehov på infrastrukturen til den norske elektrifiserte jernbanen har ført til økte påkjenninger på de elektrotekniske systemene og deres tilhørende komponenter. Denne utviklingen har motivert en ... -
A study of the reliability of the RBTS distribution system with incorporation of Distributed Generation and Batteries
(Master thesis, 2022)Denne oppgaven presenterer et grunnlag for å forstå prosedyren av pålitelighetsevaluering for distribusjonssystemer, ved å bruke både analytiske og simulasjonsmetoder, for å estimere sannsynligheten for at systemet ikke ... -
A study on optimal utilization of electric heating for buildings
(Master thesis, 2020)Fra januar 2020 er oppvarming i bygninger basert på olje og gass ulovlig i Norge. I tillegg forventes det et strengere lovverk for bygninger fremover, for å kunne møte målene som er satt med tanke på reduksjon av CO2-utslipp. ... -
A Substation Level State Estimator for Local Data Processing - Algorithms for Power System Monitoring
(Master thesis, 2017)Modelling power systems with substation details in State Estimation (SE) has several advantages. An increased measurement redundancy is possible, because the measurements can be evaluated individually instead of being ... -
A Wide Area Load Shedding Scheme to Prevent Voltage Instability
(Master thesis, 2016)These days, power systems are operated close to their stability limit, and disturbances such as transmission line contingencies can cause the system to lose stability. If the system loses stability, countermeasures has to ... -
Ablation-Assisted Current Interruption in a Medium Voltage Load Break Switch: An Experimental Study with Polypropylene as Ablation Material
(Master thesis, 2014)Near an electric arc some polymers can change the properties of an arcing medium in a beneficial manner. Such polymers, known as ablation material, decompose and evaporate when exposed to heat from an electric arc. The ... -
AC and DC systems interaction-opportunities and challenges of exchanging system services
(Master thesis, 2018)Today, the world is facing a situation where only having an energy source is not the final priority, but, also having a clean energy source is the final concern. Where clean energy generation is concerned, only renewable ... -
AC Electrical Breakdown Strength of Solid Solid Interfaces - A study about the effect of elasticity, pressure and interface conditions
(Master thesis, 2015)In several electrical insulation components, such as cable connectors, joints and penetrators, various solid insulating materials are usually brought in contact, forming interfaces. The dielectric strength of these ... -
AC Loss in MgB2 Superconductors: Calorimetric Loss Measurement
(Master thesis, 2012)Ever since the phenomenon of superconduction was discovered, and especially after the discovery of high-temperature superconductors (HTS) in the mid-80s, there has been high expectations to what could be achieved by this ... -
AC losses in MgB2 superconductors
(Master thesis, 2007)This Master thesis studies losses in superconductors. Losses arise when the superconductor carries alternating current or is placed in an alternating magnetic field. As most power applications involve at least one of the ... -
