Electricity demand is present / Private wire / Geschlossenes verteilernetz.

If one or more electricity demands are present in a project the calculation of the operation it affects the automatic calculation of the operation strategy.

First, an additional set of net heat production costs is calculated based on covering the electricity demand. This means that “ExportedElectricity” and “ImportedElectricity” is interpreted as follows:

Function	Return value
ExportedElectricity	0
ImportedElectricity	EC - EP

Based on the two sets of net heat production costs (the “electricity export” and the “covering own electricity demand”) is calculated a weighted average, dependent on the electricity production capacity of the unit and the residual electric electric demand that are not met in each time step. The residual electric demand and hence the priority is calculated dynamically. This means that the priority of a specific production unit in a specific time step is dependent on already planned production on other production units in the time step.

Priority number when residual electricity demand is 0% of electricity production capacity:

100% * ”electricity export” + 0% * ”covering own electricity demand”

Priority number when residual electricity demand is 50% of electricity production capacity:

50% * ”electricity export” + 50% * ”covering own electricity demand”

Priority number when residual electricity demand is 100% or more of electricity production capacity:

0% * ”electricity export” + 100% * ”covering own electricity demand”
