we want to model an energy system in Oemof without defining a demand and which enables to generate revenues based on the electricity injected into the grid for example electricity from rooftop solar photovoltaic or biomass power plants. we tried that and we used a sink with negative variable costs (variable_costs<0). Unfortunately it has done not worked.
We are wondering wether it’s possible oemof to set up an energy system without demand (
nominal_value= 0 fix=0) ? or maybe our approach is not adequate to solve that.
I’m grateful for any help or hint
