North Sea offshore network and energy storage for large scale integration of renewables
(Journal article; Peer reviewed, 2014)This review investigates different aspects of the realization of a North Sea offshore grid. The North Sea region has several characteristics that make large-scale integration of renewable energy sources attractive, such ... -
Norway as a Battery for the Future European Power System – Comparison of Two Different Methodological Approaches
(Chapter, 2019)This paper compares the simulation results for two stochastic optimization power market models. EMPS uses aggregation and heuristics to calculate the optimal dispatch. SOVN simulates the operation of the power system in ... -
Norway as a Battery for the Future European Power System—Impacts on the Hydropower System
(Journal article; Peer reviewed, 2017)Future power production in Europe is expected to include large shares of variable wind and solar power production. Norway, with approximately half of the hydropower reservoir capacity in Europe, can contribute to balance ... -
Norway as Swing Producer
(Master thesis, 2011)This paper looks closer at using Norwegian hydropower for swing production towards Continental Europe. On-going discussions suggest that Norwegian resources could be utilised to a larger extent, and thereby enable further ... -
Norwegian Day-ahead Electricity Price Forecasting using AI Models
(Master thesis, 2022)Omleggingen fra de regulerte, lokale monopolkraftmarkedene i Norge til liberaliseringen av krafthandelen som følge av energiloven i 1991, har skapt konkurransekraft blant markedsaktørene. I tillegg kommer den nylige ... -
Norwegian Energy Scenarios
(Master thesis, 2017)The penetration of renewable energy sources is increasing in the European power system. Their interaction with the power market is fundamentally different from that of traditional thermal power production. This thesis aims ... -
Norwegian hourly residential electricity demand data with consumer characteristics during the European energy crisis
(Peer reviewed; Journal article, 2023)This dataset was collected to understand how Norwegian households responded to the electricity price shock due to the European energy crisis. It consists of consumer characteristics and their self-reported responses to the ... -
Norwegian Hydropower and large scale Wind Generation in the North Sea
(Master thesis, 2011)The addressed issue for this report is the making of a model, which represents the power system in Great Britain. This model is connected to an already existing model of Northern Europe in order to study how the present ... -
Norwegian pumped hydro for providing peak power in a low-carbon European power market - Cost comparison against OCGT and CCGT
(International Conference on the European Energy Market;, Chapter, 2015)This paper presents an analysis of the cost of providing peak generation from new OCGT, CCGT and Norwegian pumped hydro plants in a European power system with high penetration of wind and solar power. A method for calculation ... -
Novel donation sharing mechanisms under smart energy cyber-physical-social system and DLT to contend the energy poverty problem
(Peer reviewed; Journal article, 2021)The objective of this study is to introduce a new use case under smart energy cyber-physical-social system (CPSS) that brings together the competence of distributed ledger technology (DLT) and essence of peer-to-peer local ... -
A Novel Health Monitoring System for Synchronous Generators using Magnetic Signatures
(Doctoral theses at NTNU;2022:297, Doctoral thesis, 2022)The Ph.D. research work presented in this thesis deals with the health monitoring of synchronous generators utilized in hydropower plants. Although various methods are available for fault detection in synchronous generators, ... -
Nozzle Wear and Pressure Rise in Heating Volume of Self-blast Type Ultra-high Pressure Nitrogen Arc
(Journal article; Peer reviewed, 2019)This paper reports on experiments with ultra-high pressure nitrogen arcs in a self-blast type switch design. The effect of filling pressure on nozzle mass loss and pressure-rise in the heating volume is investigated. An ... -
NTNU-SINTEF SolarNet: A solar irradiation monitoring network at high latitudes
(Peer reviewed; Journal article, 2023)This study presents a monitoring network for solar irradiation at high latitudes, called NTNU-SINTEF SolarNet. The network collects, with a time resolution ranging from seconds to hours, solar irradiance data, e.g. global ... -
Numerical Analysis of Condensation and Frost in Rotary Heat Exchangers
