Other models: Sisyfos and Stream

The SisyfosR model

In cooperation with the Danish Energy Agency, Ea Energy Analyses developed a new version of the model Sisyfos, called SisyfosR, which calculates about a 100 times faster than the previous model. SisyfosR calculates security of supply using stochastic analysis, to find the frequency of situations where the demand of electricity cannot be met.

The starting point is that power plants and transmission connections have a certain risk of outtage. The model calculates the probability of situations where not all electricity demand can be served (ENS). The probability of outage at power plants as well as transmission connections is used to calculate ENS by running a huge number of random cases, e.g. 5-10 million. Thereby, even rare situations can be described. SisyfosR delivers the results with no regards to economics or optimal dispatch. It is a stochastic analysis, and it is a powerful model for calculating security of supply.

 

The STREAM modelling tool

The STREAM modelling tool provides a quick insight into the different potential energy mixes for defined regions or countries. The model allows planners, politicians, students and others to be able to create scenarios on demand. This modelling tool was originally developed for a project titled the ”The future Danish energy system”, carried out from 2004-2007.
