The Portfolio Perspective in Electricity Generation and Market Operations
(International Conference on the European Energy Market;, Chapter; Peer reviewed, 2018)Selecting portfolios of electricity production assets, energy sources and market participation strategies facilitates usage and management of complementary resources. It helps also power producers to address uncertainties ... -
Hydropower and fish – Report and messages from workshop on research and innovation in the context of the European policy framework
(Journal article; Peer reviewed, 2018)Hydropower is the world's largest renewable electricity source and will have an important role in the future energy system with increased requirements to integrate environmental and socioeconomic aspects of sustainability. ... -
Improving carbon efficiency and profitability of the biomass to liquid process with hydrogen from renewable power
(Journal article; Peer reviewed, 2018)A process where power and biomass are converted to Fischer-Tropsch liquid fuels (PBtL) is compared to a conventional Biomass-to-Liquid (BtL) process concept. Based on detailed process models, it is demonstrated that the ... -
Anomaly indicators for Kaplan turbine components based on patterns of normal behavior
(Chapter; Peer reviewed, 2018)This paper describes and proposes some indicators for continuous monitoring of anomalous conditions in the hydraulic system of a Kaplan turbine using SCADA data. The indicators are based on significant deviations between ... -
Hydrothermal liquefaction of organic resources in biotechnology: how does it work and what can be achieved?
(Journal article; Peer reviewed, 2018)Increasing the overall carbon and energy efficiency by integration of thermal processes with biological ones has gained considerable attention lately, especially within biorefining. A technology that is capable of processing ... -
Assessing Smoothing Effects of Wind Power around Trondheim via Koopman Mode Decomposition
(Journal article; Peer reviewed, 2018)To cope with a large-scale introduction of renewables into power systems, it is important to understand the reduction of variability in the aggregated generation or the so-called smoothing effect. Knowledge of the degree ... -
System model derivation of the CO2 two-phase ejector based on the CFD-based reduced-order model
(Journal article; Peer reviewed, 2018)The developed reduced-order model (ROM) of the R744 two-phase ejector was presented in this paper. The proper orthogonal decomposition (POD) model was employed together with the radial basis function (RBF) to evaluate the ... -
