Information
DailyHeatProfile
1. General Description
The profile ist taken from
[1] H. Gadd and S. Werner, “Heat load patterns in district heating substations,” Appl. Energy, vol. 108, pp. 176–183, 2013.
... scaled to its mean value and multiplied to the input profile such that the energy consumption (in MWh) is conserved.
See: TransiEnt.Distribution.Heat.HeatGridControl.Check.TestDailyHeatProfile for how this work
Only the profile for December - February has been taken. TODO: Digitize all others from Figure 1 and apply accordingly
