modelDHNPowerScheduler_L0

Sample model to calculate amount of power to be generated by large scale CHP plants
Diagram of DHNPowerScheduler_L0

Extends from TransiEnt.Basics.Icons.LargeController (Icon for controller models).

Information

1. Purpose of model

Calculates amount of power to be generated by the Combined Heat and Power plants based on

* The amount of heating power that they should provide (time series)

* Power price in the spot market (time series)

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

PQ Diagrams are used for this

3. Limits of validity

4. Interfaces

Inputs:

* Q_flow_Target_WT: takes the heat flow to be supplied by one of the CHP plants [W]

* Q_flow_Target_WW: takes the heat flow to be supplied by one of the CHP plants [W]

* spotPrice: takes the value of the spot price [Eur/MWh]

* P_out_WT: delivers the target value of power generation to one of the CHP plants [W]

*P_out_WW: delivers the target value of power generation to one of the CHP plants [W]
