Scheduling when Reservoirs are Batteries for Wind- and Solar-power
(Journal article; Peer reviewed, 2016)In this paper we take the perspective of a competitive hydropower producer located in Southern Norway, and calculate the profitability of investing in a pumped storage facility in price-scenario for Europe in 2050. A ... -
Optimal medium-term hydropower scheduling considering energy and reserve capacity markets
(Journal article; Peer reviewed, 2016)Print Request Permissions This paper describes a method for optimal scheduling of hydropower systems for a profit maximizing, price-taking, and risk neutral producer selling energy, and capacity to separate and sequentially ... -
A novel bench size model coalescer: Dehydration efficiency of AC fields on water-in-crude-oil emulsions
(Journal article; Peer reviewed, 2016)We describe herein the design of a small AC electrostatic model coalescer for investigating coalescence efficiency of water in oil emulsions. The function of the model coalescer is tested on emulsions with different water ... -
Eliminating Measurement Cable Effects From Transformer Admittance Measurements
(Journal article; Peer reviewed, 2016)Admittance frequency-sweep measurements is an accepted procedure for characterizing transformer terminal behavior for the purpose of frequency-dependent black-box modeling. The errors introduced by the measurement cables ... -
Charcoal "Mines" in the Norwegian Woods
(Journal article; Peer reviewed, 2016)This paper presents lab-scale flash carbonization (FC) experiments under elevated pressure using Norwegian wood as a feedstock. The silicon and ferrosilicon industry of Norway has been urged to reduce fossil CO2emissions ... -
The spinodal of single- and multi-component fluids and its role in the development of modern equations of state
(Journal article; Peer reviewed, 2016)The spinodal represents the limit of thermodynamic stability of a homogeneous fluid. In this work, we present a robust methodology to obtain the spinodal of multicomponent fluids described even with the most sophisticated ... -
Experimental investigation on ablation-assisted current interruption - Experimental setup and preliminary results
(Chapter, 2016)This paper presents a flexible setup to investigate ablation-assisted interruption of load currents. The electrical test circuit is grid connected with a transformer secondary voltage from 6.9 kV to 24 kV. The applied ... -
Results of Investment Analysis in Power Transmission in Latvia and Lithuania

Smoothing of Offshore Wind Power Variations with Norwegian Pumped Hydro: Case Study
(Journal article; Peer reviewed, 2016)The solar and wind energy production in the European countries has been growing in the last years and the need of energy storage too. One of the most competitive technologies already available for large-scale balancing is ... -
Opprusting og utvidelse av Reinforsen kraftverk i Ranaelva : konsekvenser for vandring hos anadrom laksefisk forbi Reinforsen og forslag til tiltak for å sikre vandring
(SINTEF Energi. Rapport;TR A7554, Research report, 2016)Prosjektets formål har vært å vurdere konsekvensene av en opprusting av Reinforsen Kraftverk på vandring hos anadrom laksefisk forbi Reinforsen i Ranaelva, samt å foreslå tiltak mot uheldige konsekvenser. To alternative ... -
Investigation on Fault-ride through Methods for VSC-HVDC Connected Offshore Wind Farms
(Journal article; Peer reviewed, 2016)This paper proposes a novel fault-ride through method for offshore wind farms connected to grid through a voltage source converter (VSC)-based high voltage direct current (HVDC) transmission. The proposed method introduces ... -
Climate Change and Increased Irrigation Demands: What Is Left for Hydropower Generation? Results from Two Semi-Arid Basins
(Journal article; Peer reviewed, 2016)In this study, we have modelled the effect of climate change and increased irrigation withdrawals on the available water for hydropower production in two semi-arid river basins, i.e., Kizilirmak (Turkey) and Devoll (Albania), ... -
Techno-economic evaluation of the effects of impurities on conditioning and transport of CO2 by pipeline
(Journal article; Peer reviewed, 2016)This paper describes a detailed technical and economic assessment of conditioning and transporting 13.1 MTPA CO2 with impurities in an on-shore pipe-line over a distance of 500 km. The impurities that are included in the ... -
