SUMMARYThe Norwegian system operator plans to change from (N-1) to a more flexible cost-based security criterion. The approach is illustrated using a simple example and then compared with alternative decision paradigms. The comparison shows how different paradigms may change ranking of operating alternatives and that the new cost-based criterion still tends to favor alternatives close to (N-1), provided application of a penalty factor giving additional and significant weight on interruption costs.

The current reforms in the energy sector and the resulting new business opportunities have imposed a need for knowledge and skills to be acquired by or imparted to all those who will assume new roles and responsibilities in the energy sector. To this end the Faculty of Electrical Engineering and Computing of the University of Zagreb (FER), Hrvatska elektroprivreda d.d. - The Croatian Electricity Company (HEP d.d.) and the Norwegian company Technor Energy AS launched a project to establish the Training Centre for Energy Trading (TCET). This article presents the results of this co-operation - printed materials to serve as teaching aid and a market simulator to help various market participants from different countries and with different market interests to try their hand at market competition by playing games. This is the fi rst training centre project of this kind in Europe, co-fi nanced by the Ministry for Foreign Affairs of the Kingdom of Norway and HEP d.d.
