Voltage Support in Distribution Grids by Model Predictive Control of the Grid Interface Converter for a Battery Energy Storage System
(Master thesis, 2023)Elektrifiseringen av dagens samfunn og den økte mengden av distribuert energiproduksjon har ført til økt press på strømnettet. Dette presset kan resultere i utfordringer knyttet til nettstabilitet, spenningskvalitet og ... -
Voltage support strategies for Overvoltage Prevention of Distributed Solar Inverters in Low-Voltage Networks
(Master thesis, 2016)The increasing penetration of distributed photovoltaic generation in low voltage distribution networks has led to higher risk of overvoltage. This has made it necessary to utilize the capability of the inverter in the ... -
Voltage Support with Reactive Power from Fast Charging Stations with Local Energy Storage and Production
(Master thesis, 2021)Norge er ledende innen elektrisk mobilitet, og norske myndigheter har et mål om at alle passasjerbiler, lette varebiler og bybusser skal være nullutslippskjøretøy innen 2025. Med økt elbilandel vil også behovet for ... -
Voltage tuning of spin and charge supercurrents in a spin-active Josephson Junction
(Master thesis, 2018)Charge and spin-supercurrents in a spin-active Josephson junction is investigated through the quasiclassical theory of superconductivity. Analytical work has been performed and numerical results are presented, showing that ... -
Voltage Upgrading of Overhead Lines
(Master thesis, 2010)Statnett wants to increase the transmission capacity in their 300 kV overhead lines by upgrading the operating voltage to 420 kV. To make this possible some modifications must be done. Insulator strings have to be elongated ... -
Voltage-dependency of loads and its role in voltage control strategies
(Master thesis, 2019)En spenningsreguleringsstrategi kan sees på som et bevisst valg tatt av nettselskapet om å holde spenningene i nettet i den nedre eller øvre delen av det tillatte spenningsbåndet gitt i Forskrift om leveringskvalitet (FoL). ... -
Voltage-independent GluN2A-type NMDA receptor Ca2+ signaling promotes audiogenic seizures, attentional and cognitive deficits in mice
(Peer reviewed; Journal article, 2021)The NMDA receptor-mediated Ca2+ signaling during simultaneous pre- and postsynaptic activity is critically involved in synaptic plasticity and thus has a key role in the nervous system. In GRIN2-variant patients alterations ... -
Voltage-induced thin-film superconductivity in high magnetic fields
(Journal article; Peer reviewed, 2018)We predict that superconductivity in mesoscopic thin films can be stabilized in high magnetic fields if the superconductor is driven out of equilibrium by a DC voltage bias. For realistic material parameters and temperatures, ... -
