Swedish to English Science Energy / Power Generation modelling different energy scenarios

This is a document about modelling scenarios with different types of energy.

Example sentence: 'Råolja ingår inte explicit i modellbeskrivningen'

Another example: 'Biobränslen beskrivs i modellen genom utbudskurvor'

I don't know if beskrivning / beskrivs here is a way of saying 'modelled', as in 'biofuels are modelled through supply curves' or if it means something else? (described / model description?)

thank you!
