Deficits do not seem to occur in households when expected #1392
Comments
I thought I did but I'm actually not able to fully reproduce this bug. When maximally installing air-sourced heat pumps and increasing the typical useful demand values to 500 kWh/m2 for each category, barely any deficits occur. Changing the installed capacity per heat pump unit doesn't change anything. I think it was a variation on a scenario like this. |
The Or is there more to investigate that I'm not seeing? |
Ah interesting, I thought we were gonna drop that attribute. @mabijkerk what are your latest thoughts on the |
Thanks for pointing this out @noracato! I also thought that we would drop that attribute. We could instead set the This still produces an unexpected result though. In a blank DIVIDE(
MAX(FEVER_DEMAND_CURVE(V(households_useful_demand_for_space_heating_detached_houses_before_1945))),
V(households_useful_demand_for_space_heating_detached_houses_before_1945,number_of_units)
)*1000
5.466262439750358 This seems like a minor issue to follow up on at some point. For now I will make no changes. When we follow up on this issue we can decided whether or not to change the |
When I open a blank

scenario, I set the condensing combi boiler (gas) to 100% for households.I can get the demand curve of apartments before 1945:
FEVER_DEMAND_CURVE(V(households_useful_demand_for_space_heating_apartments_before_1945))
. The maximum value of that curve is 3006 MW demand in a single hour. With the number of units set to 540698, the maximum demand of single residence is 5.56 kW.I would therefore expect deficits to occur when I set the
heat_output_capacity
of thehouseholds_space_heater_combined_network_gas
to 5.5 kW or lower in the dimensioning section: https://beta.energytransitionmodel.com/scenario/demand/households_heating_order/capacities. However, if I set the relevant inputhouseholds_heater_combined_network_gas_heat_output_capacity
to 5.5 kW, no deficits appear in the deficit table. Only when I set the capacity to 5.0 kW, deficits appear:This is relatively close to what is expected, but I'm still wondering why this difference occurs. During testing we also encountered an example where the difference was larger, but I can't reproduce it now. Maybe @redekok knows when this occured?
