Classification and analysis of impact on small-signal dynamics and stability from expansion of VSC-HVDC systems to multi-terminal HVDC grids
(Chapter, 2017)This paper presents a structured approach for analysing the effect of HVDC transmission system expansion on the small signal dynamics. The methodology decomposes the expansion of the system into a sequence of steps and ... -
CLIQ Based Quench Protection of 16 [T] Nb3Sn Block-Coil Dipole Magnets for a Future Circular Collider
(Master thesis, 2015)Protection of large high-field, high-energy accelerator magnets is very challenging with current technology. To avoid damage to the magnet coil by local or global overheating, the maximum temperature in the hot-spot of the ... -
Closest security boundary for improving oscillation damping through generation redispatch using eigenvalue sensitivities
(Journal article; Peer reviewed, 2018)This paper proposes an algorithm for determining a minimum generation redispatch capable of moving specific oscillation modes to the closest small-signal security boundary that guarantees them a desired damping factor. The ... -
Closing the loop: Tracking stocks and flows of steel from the end of useful life to re-melting
(Master thesis, 2014)Recycling steel scrap from different stages in the life cycle is an important input to secondary steel production and manufacturing. While flows and losses from pre-consumer processes are well known, there are considerable ... -
Clustering methods assessment for investment in zero emission neighborhoods’ energy system
(Peer reviewed; Journal article, 2020)This paper investigates the use of clustering in the context of designing the energy system of Zero Emission Neighborhoods (ZEN). ZENs are neighborhoods who aim to have net zero emissions during their lifetime. While ... -
Clustering of AMS-data
(Master thesis, 2020)Utrullingen av AMS (smarte strømmålere) man ser i dag, både i Norge og globalt, gjør store mengder strømdata (AMS-data) tilgjengelig. På disse AMS-dataene kan man bruke Big-Data teknikker, og clustering er en teknikk mye ... -
Co-Simulation Model for Optimal Wind-Hydro Coordination Using Wind Farm Control Dynamics: A Case Study of a Hybrid Wind and Hydro Plant System
(Master thesis, 2023)Den økende andelen variabel fornybar energi i kraftsystemene medfører utfordringer for reguleringsmyndigheter, nettoperatører og energiprodusenter. Variable energikilder har begrenset fleksibilitet i driften sin, da de er ... -
Co-Simulation of an IPMSM Drive Using Comsol and Simulink
(Master thesis, 2021)Endelig elementmetoder (FEM) er standardtilnærmingen for å vurdere ytelse og design til elektriske maskiner. Permanent-magnet-synkron-motorer med innfelte magneter (IPMSM) øker i popularitet innen trekkapplikasjoner, romfart ... -
