A generic framework for power system flexibility analysis using cooperative game theory
(Journal article; Peer reviewed, 2017)Electricity grid infrastructures provides valuable flexibility in power systems with high shares of variable supply due to its ability to distribute low-cost supply to load centers (spatial), in addition to interlinking a ... -
A harmonic pressure differential wave energy converter
(Journal article; Peer reviewed, 2017)A pressure differential sea wave energy converter concept using the forced harmonic motion of a hydraulic water column and hydraulic piston is presented. The mechanical power from the hydraulic piston is converted to ... -
A linear State-Space Model of an Offshore Wind Turbine, Implemented in the STAS Wind Power Plant Analysis Program
(SINTEF Energi. Rapport;TR A7474, Research report, 2015)A set of MATlab/Octave scripts have been developed, which output state matrices describing the linearized aerolastic dynamics of an offshore wind turbine. The aerodynamic model is based on momentum balance,and includes ... -
A method for simulating two-phase pipe flow with real equations of state
(Journal article; Peer reviewed, 2014)Common two-fluid models for pipe flow assume local non-equilibrium regarding phase transfer. To solve the two-fluid models together with accurate equations of state for real fluids will in most cases require mechanical, ... -
A mobile application for on-site risk based decision support
(CIRED Conference Proceedings;2017, Chapter; Peer reviewed, 2017)Maintenance and renewal decisions are essential parts of distribution system asset management as means to control cost, performance and risk. This paper reports on the development of a mobile application used for in-the-field ... -
A Model for Techno-Economic Optimization of Wind Power Combined with Hydrogen Production in Weak Grids

A modified homogeneous relaxation model for CO2 two-phase flow in vapour ejector
(Journal article; Peer reviewed, 2016)In this study, the homogenous relaxation model (HRM) for CO2 flow in a two-phase ejector was modified in order to increase the accuracy of the numerical simulations The two- phase flow model was implemented on the effective ... -
A new approach to the identification of high-potential materials for cost-efficient membrane-based post-combustion CO2 capture
(Journal article; Peer reviewed, 2018)Developing “good” membrane modules and materials is a key step towards reducing the cost of membrane-based CO2 capture. While this is traditionally being done through incremental development of existing and new materials, ... -

A robust method for calculating interface curvature and normal vectors using an extracted local level set
(Journal article; Peer reviewed, 2014)The level-set method is a popular interface tracking method in two-phase flow simulations. An often-cited reason for using it is that the method naturally handles topological changes in the interface, e.g. merging drops, ... -
A steady and quasi-steady state analysis on the CO2 hybrid ground-coupled heat pumping system
(Journal article; Peer reviewed, 2017)This article contains the steady and quasi-steady state analysis on a CO2 hybrid ground-coupled heat pumping system for warm climates. The hybrid system uses a combination of ambient air and ground boreholes as a heat sink ... -
A stochastic model for contact surfaces at polymer interfaces subjected to an electrical field
(Journal article; Peer reviewed, 2018)Morphology of the contact area between solid insulation materials ultimately determines the short- and long-term electrical properties of the complete insulation system. The main purpose of this paper is to propose a ... -
