The criticality of risk management is evident when considering the information society of today, and the emergence of Future Internet technologies such as Cloud services. Information systems and services become ever more complex, heterogeneous, dynamic and interoperable, and many different...
provides semantically rich reflection layers enabling intelligent systems to reason about themselves and their surrounding context. Most reasoning processes require not only to explore the current state, but also the past history to take sustainable decisions e.g. to avoid...
This paper addresses the questions: How to calculate the cost of a start/stop cycle? How to calculate the cost of running one hour outside normal operating range, e.g., on part load? The paper presents a model for calculation of start/stop cost for individual hydropower units comprising both direct...
Sustainability and traceability of food products have received increased attention due to food safety, consumer demand on knowledge of the origin of their food and reducing food fraud. In recent years, traceability systems have been used to document and share sustainability information in food...
Flow-based market clearing will be implemented in the Nordic system in 2024. Nordic hydropower, with its large reservoirs require long-term production planning. Therefore, using exogenous flow-based constraints, we aim at approximating the flow-based domain of a model with a detailed description...
This work concerns the modeling of ramping constraints on discharge in medium-term hydropower scheduling models applied in a liberalized market context. Such models often apply a coarse time discretization to ensure reasonable computation times. Consequently, ramping constraints at a fine time...
Dette prosjektet er initiert og finansiert av Akademikerne og er en studie av hvordan automatisering og digitalisering påvirker arbeidsoppgaver og arbeidsprosesser karakteristiske for kunnskapsarbeid og de yrkene som representeres av Akademikernes tretten medlemsforeninger. Studien er mfattende og i...
The ongoing large-scale deployment of offshore wind parks creates the need for substantial investments in Voltage Source Converter (VSC) based High Voltage Direct Current (HVDC) transmission infrastructure. An investment cost model with a corresponding cost parameter set was established in 2018 to...
A hydro-thermal market model is applied to a description of the north-European electricity system. The paper describes how modelling uncertain gas and CO 2 prices affects uncertainty in calculated electricity prices. Gas and CO 2 price uncertainty are modelled using historic price variations. With...
