Aasvær, Victor Sætre; Ryssdal, Anders Strand (Master thesis, 2023)Mens samfunnet jobber mot en overgang til bærekraftige økonomier for å begrense virkningen av klimaendringer, står kraftnettet overfor økende utfordringer. Integreringen av elektrifisering og fornybare energikilder fører ... -
A distributionally ambiguous two-stage stochastic approach for investment in renewable generation
Borges, Pedro; Sagastizabal, Claudia; Solodov, Mikhail; Tomasgard, Asgeir (Peer reviewed; Journal article, 2022)The optimal expansion of a power system with reduced carbon footprint entails dealing with uncertainty about the distribution of the random variables involved in the decision process. Optimisation under ambiguity sets ... -
Efficient coordination of top-down and bottom-up models for energy system design: An algorithmic approach
Pisciella, Paolo; van Beesten, Egbert Ruben; Tomasgard, Asgeir (Journal article; Peer reviewed, 2023)To account for endogeneity effects in, e.g., energy demand, modern bottom-up energy system models are often linked to a top-down model describing the macroeconomic system. Solving such linked models involves iteratively ... -
