The impact of flexible resources in distribution systems on the security of electricity supply: A literature review
(Peer reviewed; Journal article, 2020)The power system is transitioning from the traditional one-way system to a more integrated and complex system with more active end-users and with generation and reverse power flow at the distribution level. As a part of ... -
Adaptive multiscale methods for 3D streamer discharges in air
(Peer reviewed; Journal article, 2019)We discuss spatially and temporally adaptive implicit-explicit (IMEX) methods for parallel simulations of three-dimensional fluid streamer discharges in atmospheric air. We examine strategies for advancing the fluid equations ... -
Review of technologies for DC grids – power conversion, flow control and protection
(Peer reviewed; Journal article, 2019)This study presents a comprehensive review of dc transmission technologies for future power grids, with particular emphasis on the attributes of the system components that could enhance system controllability and stability, ... -
An adaptive Cartesian embedded boundary approach for fluid simulations of two- and three-dimensional low temperature plasma filaments in complex geometries
(Peer reviewed; Journal article, 2019)We review a scalable two- and three-dimensional computer code for low-temperature plasma simulations in multi-material complex geometries. Our approach is based on embedded boundary (EB) finite volume discretizations of ... -

The flow based market coupling arrangement in Europe: Implications for traders
(Peer reviewed; Journal article, 2019)A new method for congestion management, flow based market coupling (FBMC), launched on May 21, 2015 in the Central Western European (CWE) region. Prior to this, no similar congestion method has been implemented elsewhere. ... -
LCA Analysis of Biocarbon Pellet Production to Substitute Coke
(Journal article, 2019)Biocarbon is a promising alternative to fossil reductants for decreasing greenhouse gas emissions and increasing sustainability of the metallurgical industry. In comparison to conventional reductants (i.e., coke and coal), ... -
An updated short chemical-kinetic nitrogen mechanism for carbon-free combustion applications
(Peer reviewed; Journal article, 2019)Chemical‐kinetic combustion mechanisms for hydrogen‐oxygen‐nitrogen systems, motivated originally by concerns about NOx emissions during hydrogen burning, have recently acquired renewed interest as a result of the possibility ... -
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 skeletal mechanism for prediction of ignition delay times and laminar premixed flame velocities of hydrogen-methane mixtures under gas turbine conditions
(Peer reviewed; Journal article, 2019)The aim of this study is to eliminate unimportant steps from a detailed chemical-kinetic mechanism in order to identify a skeletal kinetic mechanism that can predict with sufficient accuracy ignition delay times and laminar ... -
Operating a Battery in a Hydropower-Dominated System to Balance Net Load Deviations
(International Conference on the European Energy Market;2019, Chapter; Peer reviewed, 2019)Decreasing costs of battery storage technologies make them a viable option for providing flexibility in power systems. In this paper, we study the operations of a battery in combination with cascaded hydropower in a system ... -
Interaction of DSO and local energy systems through network tariffs
(International Conference on the European Energy Market;2019, Chapter; Peer reviewed, 2019)One crucial factor that influences distributed energy resource investments and operation is the grid tariffs. If the price signal passed on to the consumer is not representative of the actual impact of the decentralized ... -
A CFD analysis for the performance assessment of a novel design of plates-in-tank latent storage unit for freezing applications
(Science et technique du froid;2019-1, Chapter; Peer reviewed, 2019) -
Ice formation and growth in supercooled water–alcohol mixtures: Theory and experiments with dual fiber sensors
(Peer reviewed; Journal article, 2020)Increased knowledge on fluid-solid phase transitions is needed, both when they are undesired and can impair processes operation, and when strict control is required in fields such as food technology, the pharmaceutical ... -
Parametric Energy Simulations of a Nordic Detached House Heated by a Wood Stove
(Peer reviewed; Journal article, 2020)Wood stoves are widely used in Nordic countries. They offer a good opportunity to use biomass for space-heating and to reduce the peak power of all-electric buildings. However, wood stoves are highly concentrated heat ... -
Inside the aluminum contact spot
(Chapter; Peer reviewed, 2019)The electrical properties of a power connector – such as the resistance during its service life – depend on the number, size and quality of the tiny contact spots (“a-spots”) where the current crosses the contact interface. ... -
High temperature industrial heat pumps utilising natural working fluids
(Actes du ... Congres international du froid;ICR2019, Chapter; Peer reviewed, 2019)There is a large demand for heat typically in the temperature range 100-200⁰C in different industries. This is today often covered by fossil fuel burning or direct use of electricity. Heat pumps has to a lesser extent been ... -
High-temperature heat pumps based on natural working fluids to produce district heating from industrial waste heat.
(Science et technique du froid;2017-2, Chapter; Peer reviewed, 2017)The amount of industrial waste heat produced in Europe annually corresponds to the total annual heating demand in buildings. Common barriers for utilizing this heat are the lack of required infrastructure, i.e. a district ... -
Documentation of an integrated thermal energy system for a building complex
(Actes du ... Congres international du froid;ICR2015, Chapter; Peer reviewed, 2015)In large buildings and building complexes, energy use can be reduced by efficient interaction between heating and cooling demands and thermal storage (short and long term storage). This work describes an integrated energy ...
