1 month ago I delved into this issue a bit further, it seems that this occurs due to the energy_heat_flexibility_p2h_boiler_electricity and the energy_heat_flexibility_p2h_heatpump_electricity nodes.
With the following inputs, the error occurs on the node energy_heat_backup_burner_mt_network_gas:
households_heater_coal_share: 0.0 households_heater_combined_hydrogen_share: 0.0 households_heater_combined_network_gas_share: 0.0 households_heater_crude_oil_share: 0.0 households_heater_electricity_share: 0.0 households_heater_heatpump_air_water_electricity_share: 0.0 households_heater_heatpump_ground_water_electricity_share: 0.0 households_heater_heatpump_pvt_electricity_share: 0.0 households_heater_hybrid_heatpump_air_water_electricity_share: 0.0 households_heater_hybrid_hydrogen_heatpump_air_water_electricity_share: 0.0 households_heater_network_gas_share: 0.0 households_heater_wood_pellets_share: 0.0 households_heater_district_heating_mt_steam_hot_water_share: 100.0 households_heater_district_heating_lt_steam_hot_water_share: 0.0 households_heater_heatpump_surface_water_water_ts_electricity_share: 0.0 share_of_energy_heat_flexibility_p2h_boiler_ht_electricity: 0.0 share_of_energy_heat_flexibility_p2h_boiler_mt_electricity: 100.0 share_of_energy_heat_flexibility_p2h_heatpump_ht_electricity: 0.0 share_of_energy_heat_flexibility_p2h_heatpump_mt_electricity: 100.0 wtp_of_energy_heat_flexibility_p2h_boiler_electricity: 300.0 wtp_of_energy_heat_flexibility_p2h_heatpump_electricity: 300.0 capacity_of_energy_heat_flexibility_p2h_boiler_electricity: 63780.9 capacity_of_energy_heat_flexibility_p2h_heatpump_electricity: 21489.2
In order to see this, I set the output.steam_hot_water to 1.00 (is currently 1.03)
In this [scenario] (https://beta.energytransitionmodel.com/scenarios/2402130), the energy_heat_backup_burner_ht_network_gas shows the following energy input & output:
Part of this imbalance can be attributed to the output efficiency of this node : 1.03.
However, when this efficiency is set to 1.0, an imbalance remains:
This imbalance probably arises due to hourly calculations in the heat network. When I remove the hourly network heat attributes from the node, it is balanced:
This issue causes the sankey export queries to be slightly imbalanced.
