Optimal combination of bioenergy and solar photovoltaic on abandoned cropland for renewable energy production
(Master thesis, 2020)Transformasjonen av globale energisystem er framleis langt frå nivåa som krevjast for å stabilisere den globale oppvarminga til 1.5 grader Celsius i forhald til den førindustrielle æra. Dei mest ambisiøse scenario for ... -
Optimal combination of natural and mechanical ventilation in ZEB Laboratory
(Master thesis, 2019)Bygningssektoren er en energiintensiv sektor, med et forbruk på over 40% av det totale energiforbruket i Norge. Energien forbrukes blant annet til oppvarming og nedkjøling av bygninger. Et stort energiforbruk skyldes derfor ... -
Optimal Comfort with Limited Power
(Master thesis, 2018)Electricity consumption is growing and with more efficient equipment introducing larger power peaks. Reducing the power peaks can substantially reduce the electricity expenses for a building. In 2015 it was presented that ... -
Optimal Compensation of Harmonic Propagation in a Multi-Bus Microgrid
(Journal article; Peer reviewed, 2016-05)This paper discusses how an Active Power Filter (APF) can be utilized for system-wide harmonic mitigation in a microgrid with multiple sources of harmonic distortion located at different buses. A two-bus microgrid system ... -
Optimal configuration of supply logistics for remote oil and gas fields
(Master thesis, 2013)The objective of this thesis has been to compare alternatives to improve the supply service for remote locations offshore. First the alternative of running a conventional supply service has been assessed, where the platform ... -
Optimal configuration problem identification of electrical power cable in tidal turbine farm via traveling salesman problem modeling approach
(Peer reviewed; Journal article, 2019)Electrical power cables in tidal turbine farms contribute a significant share to capital expenditure (CAPEX). As a result, the routing of electrical power cables connecting turbines to cable collector hubs must be designed ... -
Optimal Control of a Semi-Linear Parabolic System Related to Sustainable Marine Fishery
(Master thesis, 2020)Overfiske er et økende problem, og truer mange fiskebestander i verden. In denne masteroppgaven forsøker vi å finne bærekraftige fiskestrategier ved å løse et ikke-konvekst optimalt kontrollproblem. Vi begynner med å ... -
Optimal Control of Batteries and Hot Water Heaters for Energy Flexibility in Zero Emission Neighbourhoods
(Master thesis, 2019)Denne masteroppgaven har undersøkt energifleksibiliteten i et nullutslippsnabolag. Campus Evenstad, som er et pilotprosjekt i forskningssenteret for nullutslippsnabolag, har blitt brukt som eksempelstudie. Ved hjelp av en ... -
Optimal Control of Energy Storage Systems

Optimal control of flexible natural gas combined cycles with stress monitoring: Linear vs nonlinear model predictive control
(Peer reviewed; Journal article, 2020)In future energy markets, traditional thermal power plants are expected to cycle more to adapt their operation to the intermittent power generation of renewable energy sources. Gas turbine load ramps and stresses in ... -
Optimal Control of Floating Offshore Wind Turbines
(Master thesis, 2009)Floating Offshore Wind Power is an emerging and promising technology that is particularly interesting from a Norwegian point of view because of our long and windy coast. There are however still several remaining challenges ... -
Optimal Control of Multibody Dynamics with Applications
(Master thesis, 2023)Vi presenterer en metode for å representere bjelker ved hjelp av flerkroppsdynamikk, nærmere bestemt et system av stive ledd som kalles en pendelkjede. Ved å innføre ledd i uttrykket som straffer vinkler mellom påfølgende ... -
Optimal control of multiphase steel production
(Journal article; Peer reviewed, 2019)An optimal control problem for the production of multiphase steel is investigated that takes into account phase transformations in the steel slab. The state equations are a semilinear heat equation coupled with an ordinary ... -
Optimal control of secondary side supply water temperature for substation in district heating systems
(Journal article; Peer reviewed, 2019)Low temperature is the most significant feature of the future district heating system- the 4th generation district heating (4GDH). However, a widely used control strategy for supply water temperature in substation is ... -
Optimal Control of TES System by Using Nonlinear Model Predictive Control
(Master thesis, 2020)WE-utvinningsprosess (industriell spillvarme) gjenbruker varmeenergi som ellers ville gått tapt for å sikre og forbedre ressursbevaring og avfall, samt for å redusere kostnader. Under slike omstendigheter kan et termisk ... -
