A Comprehensive Framework for Vulnerability Analysis of Extraordinary Events in Power Systems
(Peer reviewed; Journal article, 2020)Electric power systems are critical infrastructures subject to the possibility of extraordinary events with high societal consequences. Although such possibilities are often associated with very low probabilities of being ... -
A Comprehensive Simulator for Hydropower Investment Decisions
(Chapter; Peer reviewed, 2022)Due to a higher share of power production from renewable sources with high short-term variation, hydro systems must more often operate closer to their components' physical limits. To simulate system behaviour, a hydropower ... -
Computation of three-dimensional three-phase flow of carbon dioxide using a high-order WENO scheme
(Journal article; Peer reviewed, 2017)We have developed a high-order numerical method for the 3D simulation of viscous and inviscid multiphase flow described by a homogeneous equilibrium model and a general equation of state. Here we focus on single-phase, ... -

Concept of hydrogen fired gas turbine cycle with exhaust gas recirculation: Assessment of process performance
(Journal article; Peer reviewed, 2019)High hydrogen content fuels can be used in gas turbine for power generation with CO2 capture, IGCC plants or with hydrogen from renewables. The challenge for the engine is the high reactive combustion properties making ... -
Conceptual Design of Experimental Test Rig for Research on Thermo-Flow Processes During Direct Contact Condensation in the Two-Phase Spray-Ejector Condenser
(Peer reviewed; Journal article, 2024)The paper presents the conceptual design of a prototype experimental facility for mixing jet-type flow condensers investigations when the steam in exhaust gases is condensed on the water jet in the presence of CO2. The ... -
Condensation heat transfer of CO2 on Cu based hierarchical and nanostructured surfaces
(Peer reviewed; Journal article, 2021)Phase-change processes such as condensation are efficient means of heat transfer. However, condensation is also an energy-intensive process and extensive research is conducted to increase the heat transfer efficiency. ... -
Condition Assessment of Hydrogenerator Stator Bar Insulation Using Partial Discharge Measurements
(Chapter; Peer reviewed, 2018)This paper presents results from laboratory measurements of partial discharge (PD) activity in 50 cm long samples cut from the mainwall section of old hydrogenerator stator bars. All stator bars were manufactured in 1976 ... -
Conduction and Electric Fields in Dielectric Liquids in Needle-to-Plane Gaps
(Peer reviewed; Journal article, 2024)This paper describes measurements of conduction currents in both neat and commercial insulating liquids. Conduction in thermodynamic equilibrium has been measured by applying a low ac voltage in a uniform field. High-field ... -
Configuration and model order selection of frequency-dependent π-models for representing dc-cables in small-signal eigenvalue analysis of HVDC transmission systems
(Peer reviewed; Journal article, 2020)Eigenvalue-based analysis of small-signal dynamics in High Voltage Direct Current (HVDC) transmission systems requires cable models that are compatible with a state-space representation. While distributed parameter models ... -
Consequences for Residential customers when changing from energy based to capacity based tariff structure in the distribution grid
(Chapter; Peer reviewed, 2017)This paper presents the trends towards capacity based grid tariffs and results from a work analysing the consequences different grid tariffs will have for residential customers, based on their consumption profile. The ... -
Consequences of Uncertainty from Intraday Operations to a Capacity Expansion Model of the European Power System
(International Conference on the European Energy Market;2023, Chapter; Peer reviewed, 2023)The European Energy Transition envisions a high deployment of variable renewable energy sources (VRES) by 2050. Some estimates expect that 60-to-70% of power generation will be entirely covered by VRES technologies (i.e., ... -
Considerations on factors affecting biocarbon densification behavior based on a multiparameter model
(Peer reviewed; Journal article, 2021)The optimization of upscaled biochar pelleting is limited by lack of knowledge regarding the effects of process parameters. A multiparameter model, coupled to a single pellet press unit, was for the first time applied to ... -
