Advanced Control Methods for Modular Multilevel Converters
Hamayoon, Saad (Doctoral theses at NTNU;2023:229, Doctoral thesis, 2023)Climate change has forced the global energy sector to transition from energy production based on fossil fuels such as oil, natural gas, and coal towards renewable energy sources i.e., solar energy, wind energy, biomass, ... -
Application of Virtual Synchronous Machines for Integration of Offshore Wind Turbines into the Power System of Offshore Oil and Gas Platforms
Mathisen, Eivind Risan (Master thesis, 2016)This thesis addresses the technology known as "Virtual Synchronous Machines" and studies an application where it is used to integrate offshore wind turbines into the power systems of oil and gas platforms. The virtual ... -
Autonomous driving of a small-scale electric truck model with dynamic wireless charging
Jon Eivind Stranden (Master thesis, 2019)Automated wireless power transfer can be seen as an enabling technology for autonomous vehicles. At SINTEF Energy Research a 1/14 scale electric truck model [13] had been used for demonstrating such technology. The truck ... -
Computer vision based path tracking for a small-scale electric truck model with dynamic or static wireless charging
Jørgensen, Mats (Master thesis, 2021)Fossildrevet tungtransport genererer betydelige utslipp av NOx og klimagasser som CO2. I Norge forventes tungtransport å øke med 65 prosent innen 2050, men Norge har som mål å redusere klimagassutslippene med 80 til 95 ... -
Control of Grid Integrated Voltage Source Converters under Unbalanced Conditions: Development of an On-line Frequency-adaptive Virtual Flux-based Approach
Suul, Jon Are (Doctoral Theses at NTNU, 1503-8181; 2012:90, Doctoral thesis, 2012)Three-Phase Voltage Source Converters (VSCs) are finding widespread applications in grid integrated power conversion systems. The control systems of such VSCs are in an increasing number of these applications required to ... -
Control of Permanent Magnet Synchronous Motors for drones
Aasen, Sondre (Master thesis, 2022)Forskningen på ‘fixed wing’ vertikale start- og landingsdroner (VTOL) vokser raskt, med økende fokus på smidige kontrollsystemer og kostnadsreduserende tiltak. Denne oppgaven har som mål å bidra til denne forskningen ved ... -
An Integrated Method for Generating VSCs’ Periodical Steady-state Conditions and HSS-based Impedance Model
Molinas Cabrera, Maria Marta; Zhang, Chen; Føyen, Sjur; Suul, Jon Are; Takanori, Isobe (Peer reviewed; Journal article, 2020)This paper proposes an integrated method for generating the voltage-source-converters’ (VSCs’) periodical steady-state (PSS) conditions and the harmonic-state-space (HSS)-based impedance model. Since these two objectives ... -
Model Predictive Control of a Variable Speed Back-up Diesel Generator Interfaced to an AC Ship Power System as a Virtual Synchronous Machine
Jenssen, Magnus (Master thesis, 2021)Dieselelektriske marine kraftsystemer kan bli utsatt for store belastningsvariasjoner. Belastningen kan for eksempel variere imellom full fremdrifts-belastning og veldig lav hotel-belastning. Drivstoff-effektiviteten i et ... -
Modeling and control of inductive power transfer systems with constant voltage load
Zhou, Jiayu (Doctoral theses at NTNU;2023:107, Doctoral thesis, 2023)In recent decades, wireless power transfer (WPT) systems have been used in more and more fields, such as portable electronic devices, implanted medical devices, power system monitoring devices, underwater vehicles, etc. ... -
Optimal Charge Planning in Hybrid Ferry Systems
Finnekås, Morten Volland (Master thesis, 2019)Klimaendringene er uten tvil en av de største utfordringene vår generasjon står ovenfor. Ny teknologi utvikles imidlertid som følge av denne utfordringen, og gjør sitt inntog i nye løsninger for at vi skal nå internasjonale ... -
Optimization and Control of Battery Electrode Drying Process
Oppegård, Emil (Master thesis, 2021)Batteriindustrien har opplevd en betydelig økning de siste tiårene, hovedsakelig på grunn av veksten i elbilindustrien og anvendelsene av litiumionbatterier. Litiumionbatterier spiller en viktig rolle i å redusere ... -
Optimization of transfer efficiency of a dynamic wireless charging system for electric vehicles
Khalaf, Alaa (Master thesis, 2020)A scaled down truck model equipped with a wireless dynamic charging system was the main platform for development, in this study. The goal was to enhance the efficiency of the power transfer from the road-way coil to the ... -
Performance evaluation of different Kalman filters for state estimation of lithium-ion batteries
Korsnes, Viktor (Master thesis, 2022)Litium-ion-batterier representerer en enorm industri og har vist seg å være en sentral teknologi for å redusere klimagasser. Ettersom elektrifiseringen av transportsektoren fortsetter å øke, vil de potensielle gevinstene ... -
Small-signal modelling and stability analysis of a traditional generation unit and a virtual synchronous machine in grid-connected operation
Saborio Romano, Oscar (Master thesis, 2015)In this work, previous small-signal modelling and analysis carried out for a VSM implementation has been adapted and expanded to include a synchronous machine (SM) with a control scheme similar to those of traditional ... -
