Advanced Cost Calculations

[mstich0]

Going forward, we might want some more financial indicators for the projects and the specific components. For being able to calculate actual component specific costs I'd suggest that we calculate the cost of each out-flow based on:

Energy cost of output flow at time step X = fix_cost + var_cost (X)

fix_cost = ep_costs * capacity / total yearly out-flow
var_cost = sum of all input flow costs(X) + var_cost(X)

These calculations have to be done from sources into the direction of demand (as the out flow costs are necessary to calculate the inflow cost). So e.g first the out flow cost of the Gas DSO is calculated which happens to be its var_cost. In the boiler component now there exists an input flow from the gas bus. As the Gas DSO is the only input to the bus, the outflow of the Gasbus has the same costs. In case there is more than one input the mean is calculated for the specific timestep for all inputflows and their flow amount. The cost of the Boiler out flow now contains all costs that were necessary to generate it.
This makes it now possible to calculate the levelized costs of heat just for the boiler component.

For components with more than one output a cost distribution has to be set. This could be done in the results. All components with more than one output would be listed with input fields for the cost contribution for the outflows, which can be changed from default 50:50 by the user. The cost then would have to be updated (automatically if possible).

I´m working on an example in jupyter to share here. In the meantime feel free to comment, though I know this might not read very well.
