A Virtual synchronous machine implementation for distributed control of power transformers in SmartGrids
(Journal article; Peer reviewed, 2015)The ongoing evolution of the power system towards a “SmartGrid” implies a dominant role of powerelectronic converters, but poses strict requirements on their control strategies to preserve stability andcontrollability. In ... -
Absorption of water in silicon gel
(Chapter; Peer reviewed, 2014)Water is an important enemy of an electric insulation system. Water vapour can be absorbed by electrical insulation materials (liquids or solid) and migrate in between the materials to achieve the same relative humidity ... -
AC Breakdown Voltage of 50-Year-Old Service Aged Hydro Power Generator Stator Bars
(Peer reviewed; Journal article, 2022)Randomly selected generator bars from a 50-year-old Norwegian hydro power generator were examined in this work. Typical non-destructive tests, as partial discharge and dissipation factor measurements were initially performed ... -
AC Corrosion of Electrically Heated Pipelines
(ISOPE - International Offshore and Polar Engineering Conference. Proceedings;2017, Chapter; Peer reviewed, 2017) -
AC Corrosion Tests of Carbon Steel, AlZnIn Anodes and 25Cr Duplex for Subsea Applications
(Chapter; Peer reviewed, 2021)This paper presents results from AC corrosion tests on 25Cr duplex and cathodically protected carbon steel. The results show that the corrosion rate is independent of transfer current density (0-200 A/m2) and power frequency ... -
AC Corrosion Tests on Materials for Electrically Heated Flowlines

Accelerating Efficient Installation and Optimization of Battery Energy Storage System Operations Onboard Vessels
(Peer reviewed; Journal article, 2022)Emerging large battery energy storage systems (BESSs) are key enablers in the electrification of the shipping sector. With huge government investments in BESSs, there are large gaps between the government supported BESS ... -
Accounting for component condition and preventive retirement in power system reliability analyses
(Peer reviewed; Journal article, 2023)Deteriorated power system components have a higher probability of failure than new components. Still, reliability of supply analyses traditionally model all components of the same type with the same probability of failure, ... -
Accounting for uncertainties due to high-impact low-probability events in power system development
(Peer reviewed; Journal article, 2021)In the long-term development of the electric power system, system operators should consider the socio-economic balance between grid investment costs and security of supply, including the risk of power supply interruptions. ... -
Accuracy Analysis of a Dynamic State Estimator with a Hardware in the Loop Approach
(Chapter; Peer reviewed, 2023)State estimation is critical for the monitoring and control of power systems. The conventional approach for state estimation is based on quasi static models for the power systems and as such neglects relevant dynamic ... -
Accurate quantum-corrected cubic equations of state for helium, neon, hydrogen, deuterium and their mixtures
(Peer reviewed; Journal article, 2020)Cubic equations of state have thus far yielded poor predictions of the thermodynamic properties of quantum fluids such as hydrogen, helium and deuterium at low temperatures. Furthermore, the shape of the optimal α functions ... -
Achieving 50% weight reduction of offshore steam bottoming cycles
(Peer reviewed; Journal article, 2021)Adding a bottoming cycle to the gas turbines powering offshore oil and gas production plants allows additional power to be produced from recovered excess heat. Hence, the power demand of the platform can be met by burning ... -
Achieving Enhanced Phasor POD Performance by Introducing a Control-Input Model
(Chapter; Peer reviewed, 2023)In this paper, an enhancement to the well known Phasor Power Oscillation Damper is proposed, aiming to improve its performance. Fundamental to the functioning of this controller is the estimation of a phasor representing ... -
