Common and differential mode of dc-bias in three-phase power transformers
(Peer reviewed; Journal article, 2022)Dc magnetization due to the geomagnetically induced currents (GICs) and HVDC (High Voltage Direct Current) systems may cause core saturation and result in serious destruction in the transformer performance as well as the ... -
Impact of energy communities on the European electricity and heating system decarbonization pathway: Comparing local and global flexibility responses
(Peer reviewed; Journal article, 2022)This paper investigates how the European electricity and heating system is impacted when medium-scale energy communities (ECs) are developed widely across Europe. We study the response on the capacity expansion of the ... -
Geomagnetically induced currents in a Norwegian transformer station
(SINTEF Rapport;, Research report, 2022)This report considers measurements of geomagnetically induced current (GIC) and comparison to recorded variations in the geomagnetic field (dB/dt). The GIC-sensors were installed in the neutral point of a 420 kV transformer ... -
Control of steam bottoming cycles using nonlinear input and output transformations for feedforward disturbance rejection
(Peer reviewed; Journal article, 2022) -
Stochastic operation of energy constrained microgrids considering battery degradation
(Peer reviewed; Journal article, 2022)Power systems with high penetration of variable renewable generation are vulnerable to periods with low generation. An alternative to retain high dispatchable generation capacity is electric energy storage that enables ... -

Characterization of Montmorillonite–Biochar Composite and Its Application in the Removal of Atrazine in Aqueous Solution and Soil
(Peer reviewed; Journal article, 2022)Atrazine is a widely used triazine herbicide, which poses a serious threat to human health and aquatic ecosystem. A montmorillonite–biochar composite (MMT/BC) was prepared for atrazine remediation. Biochar samples were ... -
The effect of turbulence on the conversion of coal under blast furnace raceway conditions
(Peer reviewed; Journal article, 2022)dynamics (CFD) can be used to analyze the process virtually and thus improve its performance. Different reducing agents can be used to (partially) substitute the coke and consequently reduce overall emissions. To analyze ... -
Use of Data-Driven Approaches for Defect Classification in Stator Winding Insulation
(Peer reviewed; Journal article, 2022)Partial discharges (PD) in the high voltage insulation systems are both a symptom and cause of terminal and impending failures. The use of data-driven methods based on PD measurements will enable predictive strategies to ... -
Hydrothermal Liquefaction of Bark-containing Nordic Biomass
(Peer reviewed; Journal article, 2022)Hydrothermal liquefaction (HTL) is a thermochemical process that takes advantage of the water present in the feedstock under process conditions where the water is kept as a liquid solvent using pressurized systems, avoiding ... -
Streamer Propagation along Profiled Insulator Surfaces under Positive Impulse Voltages
(Peer reviewed; Journal article, 2022)Controlling discharge growth on insulator surfaces is important in high voltage gaseous insulation systems. In this study, the effect of small-scale surface profiles on streamer discharge propagation is examined experimentally. ... -
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 ... -
Experiments and modelling of choked flow of CO2 in orifices and nozzles
(Peer reviewed; Journal article, 2022)In order to accelerate the deployment of capture and storage (CCS), engineers need experimentally validated models, among other things, to predict the mass flow rate in process equipment and flow restrictions like valves, ... -
Bayesian Optimization for techno-economic analysis of pressure swing adsorption processes
(Peer reviewed; Journal article, 2022)Pressure swing adsorption (PSA) can remove CO2 from flue gases. The full potential of the technology can only be exploited if the optimal combination of adsorbent material and process is identified. This identification ... -
Cold thermal energy storage for industrial CO refrigeration systems using phase change material: An experimental study
(Peer reviewed; Journal article, 2022)Refrigeration systems in industrial food processing plants are large users of electric energy and often show high peak power consumption. Cold thermal energy storage (CTES) technology integrated into refrigeration systems ... -
