Collective heat pump is not assigned any electricity on the input curve

[mabijkerk]

When I open the II3050v2 EUR scenario and add 7000 MW of the collective heat pump (energy_heat_heatpump_water_water_electricity), I get the following results:

The collective heat pump is therefore producing steam hot water for the heat network and consuming electricity. However, when I export all the electricity curves, the input curve of the heat pump is 0 in every hour. This is confirmed in the following query:

SUM(V(energy_heat_heatpump_water_water_electricity,electricity_input_curve))

0.0

@noracato can you look into this issue? It does not seem to occur when I install 7000 MW in a blank nl2019 scenario:

SUM(V(energy_heat_heatpump_water_water_electricity,electricity_input_curve))

835,404.3176110185

The issue also does not seem to occur for any of the other electricity consumers on the heat network in the II3050v2 EUR scenario: energy_heat_well_geothermal, energy_heat_flexibility_p2h_heatpump_electricity and energy_heat_flexibility_p2h_boiler_electricity. These all have electricity assigned to the input curve. A difference is that these are must_run producers however, whereas the collective heat pump is the only dispatchable producer on the heat network that consumes electricity.

When I follow your steps of adding the 7000MW of collective heatpump, it starts showing up in the merit order:

But it comes in place 3, after the waste heater with 0 capacity. Looking at the available capacity of the next candidate is, I believe, a stop condition for Merit. So maybe inside Merit the collective heat pump is never reached.

I'll look into this some more, but it might be a good starting point!

EDIT: no, moving it around in the merit order did nothing.
