The Aggregation of Wind Time-Series in Capacity Expansion Models
Reulein, Dana; Li, Carmen; Pinel, Dimitri; Andresen, Christian Andre; Farahmand, Hossein; Parvania, Masood (Journal article; Peer reviewed, 2025)Capacity Expansion Models (CEMs) are widely used in the academic literature to understand the needs and dynamics of highly renewable energy systems. Due to computational constraints, it is common to aggregate time-series ... -
Balancing the Breeze: Offshore Grid Connectivity and Demand Flexibility in Future Power systems
Steiro, Hanna (Master thesis, 2024)Det europeiske kraftsystemet er i endring. Målet om å bli et nullutslippssystem har ført til endringer både i forbruk og produksjon. Elektrifiseringen av sektorer som tidligere har vært drivstoffbaserte øker elektrisitet ... -
Comparative Study of Event Prediction in Power Grids using Supervised Machine Learning Methods
Høiem, Kristian Wang; Santi, Vemund Mehl; Torsæter, Bendik Nybakk; Langseth, Helge; Andresen, Christian Andre; Rosenlund, Gjert Hovland (Chapter, 2020)There is a growing interest in applying machine learning methods on large amounts of data to solve complex problems, such as prediction of events and disturbances in the power system. This paper is a comparative study of ... -
Fault Detection and Prediction in Smart Grids
Andresen, Christian Andre; Torsæter, Bendik Nybakk; Haugdal, Hallvar; Uhlen, Kjetil (Chapter, 2018)Modern society is to a larger and larger extent dependant on electric energy, and hence the reliance on and utilization of the electric grid is increasing steadily. At the same time the production and consumption patterns ... -
Impact of the Offshore Wind Development Plans in the North Sea on the Decarbonization of the European Energy System
Pinel, Dimitri; Reulein, Dana; Andresen, Christian Andre (Journal article; Peer reviewed, 2024)Large amounts of offshore wind (OW) power are expected to be installed in the North Sea in the next decades with countries aiming for a total of 300 GW by 2050 as stated in the Ostend declaration. This scale-up will help ... -
Impact of the Temporal Distribution of Faults on Prediction of Voltage Anomalies in the Power Grid
Tyvold, Torfinn Skarvatun; Torsæter, Bendik Nybakk; Andresen, Christian Andre; Hoffmann, Volker (Chapter, 2020)Is it possible to reliably predict voltage anomalies in the power grid minutes in advance using machine learning models trained on large quantities of historical data collected by power quality analysers (PQA)? Very little ... -
Large-scale Offshore Wind Development and Decarbonization Pathways of the Norwegian Energy System
Reulein, Dana; Tiwari, Shweta; Hestvik, Birk; Kvannli, Aleksander; Pinel, Dimitri; Andresen, Christian Andre; Farahmand, Hossein (Chapter, 2023)Modelling of the energy system in the countries surrounding the North Sea is performed with a focus on Norway and offshore wind farms situated in the North Sea. The geographically heterogeneous consumption and production ... -
The representation of hydrogen in open-source capacity expansion models
Reulein, Dana; Blanco, Herib; Pinel, Dimitri; Farahmand, Hossein; Andresen, Christian Andre (Journal article; Peer reviewed, 2024)The intermittent nature of wind and solar power has led to a scientific consensus in the international energy research community that a mix of energy sources and carriers is necessary to achieve carbon neutrality. The ... -
Stakeholder analysis with regards to large-scale North Sea offshore wind energy developments
Andresen, Christian Andre (Master thesis, 2023)Det er gjennomført en interessentanalyse med fokus på utbygginger av storskala havvindparker i Norge. Analysen hadde som mål å kartlegge relevante interessenter, fastsette deres mål og viktigste samarbeidspartnere og ... -
Topology of fracture networks
Andresen, Christian Andre; Hansen, Alex; Le Goc, Romain; Davy, Philippe; Hope, Sigmund Mongstad (Journal article; Peer reviewed, 2013)We propose a mapping from fracture systems consisting of intersecting fracture sheets in three dimensions to an abstract network consisting of nodes and links. This makes it possible to analyze fracture systems with the ...
