Information

District Heating Network Control

1. Purpose of model

This component takes the predicted heat load in a given district heating network and determines the output target for the heating condensers or heat exchangers heat demand of the city (in this case three units).

In other words, this components takes care of the formation of output targets for the district heating units.

2. Level of detail, physical effects considered, and physical insight

The model considers

• The supply temperature according to the contract of the company (SupplyTemperature)
• The return temperature according to the ... law (ReturnTemperature)
• The mass flow restrictions of each branch (massFlowRestrictions_EWC)

It is assumed that these values are known by the network operator. The values should be added to the tables.

3. Limits of validity

(Purely technical component without physical modeling.)

4. Interfaces

Inputs:

• Ambient Temperature in °C
• Expected load in the district heating network in W

Outputs:

• Target heatflow output at east branch
• Target heatflow output at west branch
• Target heatflow output at center
