Economic expansion in DHNx

[ddceruti]

Dear DHNx community,

I was wondering if it is possible to do an economic expansion (therefore, not all demands need to be met, only those maximizing net total costs of the network) within DHNx. The documentation clearly states this:

In addition to the first question, what is the cost-optimal expansion of a given DHS system?
Is it cost-efficient to build a DHS at all, if there a consumer-wise heat supply alternatives? (Comparison of central and de-central supply strategies)

I could not find any examples utilizing this function nor any predefined option within the code or argument to pass to the `setup_optimise_investment()' function. Am I missing something?

Thanks in advance!

Hi, sorry for the late response. You can do that to a limited extend already directly with the tabular structure provided by DHNx. You can alternatively also extract the oemof-solph model of the dhnx thermalnetwork and manually add components (such as alternative heat sources with costs) at the consumers. There are no examples at the moment. You can also check out https://github.com/SESMG/SESMG. They integrated DHNx in their tool. So, you could also check if that tool suits your needs ...
