We have in an earlier study proposed a set of requirements and an approach to identification and modelling of cybersecurity risks and their impacts on safety, within the context of smart power grids. The approach, which consisted of a process and a modelling language, was a partially customized vers...

Electric power systems are critical infrastructures subject to the possibility of extraordinary events with high societal consequences. Although such possibilities are often associated with very low probabilities of being realized, it is nevertheless crucial to be able to identify and understand the...

I takt med utfordringane knytt til økt elektrifisering blir såkalla aktive tiltak som bruk av batteri eller andre fleksible ressursar stadig meir diskutert som alternativ til tradisjonelle tiltak som nettforsterking. Nettforsterkning kan vere ganske kostbart, og den tradisjonelle måten å planlegge ...

The extensive integration of information and communication technology (ICT) in the future electrical power system transforms the power system to a cyber physical system (CPS), making it a system-of-systems. This new system topology creates interdependent relationships between the cyber and the physi...

The long-term planning frameworks currently used by electricity distribution grid companies are not designed to account for new challenges such as variable distributed generation or for new opportunities of active grid measures. Various advanced optimization methods for active grid measures are pres...

In the increasingly interconnected and integrated European power system, transmission system operators need to consider new kinds of risk associated with the interconnection to neighbouring systems. For the Nordic power system, there is now more than 8 GW of HVDC interconnector capacity connecting t...
