INVESTIGATION OF THE MATRIX CONVERTER IN A DC SERIES-CONNECTED WIND FARM: Modulation, Control and Efficiency
(Doctoral thesis at NTNU;2016:16, Doctoral thesis, 2016)In this thesis a wind energy conversion system for series-connection of DC wind turbines is considered. The wind park topology offers the advantage of a high voltage transmission without the need of an offshore platform ... -
Investigation of the Model Structure for Low-Order Grey-Box Modelling of Residential Buildings
(Chapter, 2019)Model Predictive Control (MPC) is a key technology to activate the building energy flexibility. A reliable control-based model should be developed for each specific building. The structure of grey-box models is usually ... -
Investigation of the Transient Recovery Voltage across Circuit Breakers in Networks with Distributed Energy Resources
(Master thesis, 2019)Tilkoblingen av små-skala kraftproduksjon i distribusjonsnettet har mange positive sider. Dette innebærer blant annet reduserte kostnader relatert til re-investering i transmisjonslinjer, økt pålitelighet, og en økt andel ... -
Investigation of the use of test automation in software quality assurance in Norwegian companies and organisations
(Master thesis, 2016)The focus of this thesis has been about automated testing in practice. Using testing tools is quite common phenomenon in software companies. A questionnaire about the use of testing tools in software quality assurance to ... -
Investigation of Universality in Cross-modal Correspondences Between Hue and Pitch
(Master thesis, 2023)The combination of different senses is necessary to enhance perception. There exists a hypothesis that correspondences between different modalities are processed automatically in our daily lives and thus seemingly unrelated ... -
Investigation of various solutions for improved voltage quality in weak distribution networks
(Master thesis, 2018)This thesis is investigating several solutions to improve voltage stability and the short circuit capacity of weak distribution networks. In order to do so electric machines are added to the grid and their impact is ... -
Investigation on Fault Current Making in Medium Voltage Switchgear in Air
(Doctoral theses at NTNU;2022:106, Doctoral thesis, 2022)Closing a switch under a fault condition could result in extensive electrical contact wear and a possible switch failure. A load break switch (LBS), as one of the critical components in medium voltage (MV) power grids, ... -
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 ... -
Investigation on Fault-ride Through Methods for VSC-HVDC Connected Offshore Wind Farms - Overview and New Proposal for Fault Ride Through
(Master thesis, 2015)Recently, there has been a fast development and deployment of wind energy to meet the increasing electrical power demand and to limit the use of fossil fuels. More and more wind farms are planned far from shore because of ... -
Investigation, Analysis and Implementation of Open Source Mobile Communication Software
(Master thesis, 2016)Over the past few years, open source software has transformed the mobile communication networks. The development of VoIP technologies has enabled the migration of telco protocols and services to the IP network with help ... -
Investigations on Secondary Voltage Control for Long-Term Reactive Power Management
(Chapter, 2023)Voltage and reactive power management is a crucial task for system operators worldwide, and particularly in Norway. While manual operations within regional control cen-ters were once the norm, a major shift is currently ... -
Investment Analysis for Residential Storage and PV Systems under Spanish Grid Tariffs
(Master thesis, 2020)The elimination of the so-called solar-tax in Spain at the end of 2018, which had earlier made investment in residential PV systems unattractive, has opened a new horizon for self-consumption and thereby providing an ... -
Investment Analysis with the EMPS Model with Emphasis on Central Norway
(Master thesis, 2010)Central Norway has had a significant growth in power consumption over the last few years, and demand is expected to rise. Due to lack of investment in sufficient generation and transmission capacity, Central Norway is ... -
Investment Analysis with the EMPS Model with Emphasis on Transmission Capacity Increase to other Power Systems
(Master thesis, 2010)The EMPS model is a fundatmental model for optimizing and simulation of power systems with substantial amounts of hydro power, developed by SINTEF Energy Research. Recently SINTEF Energy Research developed investment ... -
Investments in Low-Carbon Power Generation and Energy Storage under Uncertainty
(Master thesis, 2023)Denne masteroppgaven analyserer hvordan usikkerhet, ulike grader av risikoaversjon og ulike klimatiltak påvirker investeringene i, og dermed dekarboriseringen av kraftsystemet. Store investeringer innen fornybar kraftproduksjon ... -
Invisible Data Curation Practices: A Case Study from Facility Management
(Peer reviewed; Journal article, 2021)Facility management, which concerns the administration, operations, and maintenance of buildings, is a sector undergoing significant changes while becoming digitalized and data driven. In facility management sector, companies ... -
Invisible Work Pre- and Post- Digitalisation: The Case of a Health Authority in Norway
(Peer reviewed; Journal article, 2020)In this paper, we argue that, despite the increasing opportunities for transparency and visibility that come with the digitalisation of workplaces, invisible work remains a highly relevant concept, as it represents practices ... -
