Yes, I understand the desired condition "Heat supply by district heating" >= 30% of "Heat demand in the residential sector".
But how should you measure "Heat demand in the residential sector"? I guess it could probably be measured by the residential demand for space heating and hot water, do you think so? But which commodities represent these demands? Do the RDEM101, RDEM102, etc. represent those demands, i.e. demand for residential space heating and hot water? If so, you could define the UC_COMPRD coefficients for those demand commodities in the constraint specification, instead of RESHXC101, RESHXC102, RESHXC103, for which you are now defining the UC_COMPRD. You can define UC_COMPRD for the demand commodities by moving the UC_FLO specification to a separate row in the ~UC_T table, and keep your original Pset_Set, Pset_PN and Cset_CN on that row for the UC_FLO.
In principle, the efficiency of the district heating heat exchangers should then also be taken into account, but that would be only a small refinement.
