Data-driven sizing and control of energy storage for wind-powered offshore platforms – Energy Management and Control of Offshore Platforms Integrating Renewable Energy
(Doctoral theses at NTNU;2023:86, Doctoral thesis, 2023)One of the key aspects of facing the global environmental crisis and achieving sustainable development for future societies is re-thinking the way energy is produced and managed to serve the demand. This perspective calls ... -
Data-informed scenario generation for statistically stable energy storage sizing in isolated power systems
(Peer reviewed; Journal article, 2022)We consider the problem of how to generate uncertainty scenarios to be used in energy storage sizing problems in isolated power systems. More precisely, we consider storage sizing formulations where both loads and generation ... -
Datadrevet feildeteksjon i distribusjonsnettet: feilplasserte nettkunder og feil transformatorkonstant
(Bachelor thesis, 2024)Strømnettet er en av de viktigste infrastrukturene i Norge, og det sørger hver dag for at strøm blir levert til over 3,5 millioner sluttbrukere. Distribusjonsnettet er den delen av strømnettet som knytter sluttbrukerne ... -
Day-ahead inflow forecasting using causal empirical decomposition
(Peer reviewed; Journal article, 2022)It is essential to have accurate and reliable daily-inflow forecasting to improve short-term hydropower scheduling. This paper proposes a Causal multivariate Empirical mode Decomposition (CED) framework as a complementary ... -
