Interoperation of wind power and thermal power

Extends from Modelica.Icons.Example (Icon for runnable examples).

Information

This example models a control area for power distribution in island mode, i.e. without connection to a larger net. It contains the following consumers and producers:

  • a city with a load of about 1000 MW, i.e. 1 Mio inhabitants,
  • a thermal power plant with
    • 800 MW nominal power
    • 60 MW for secondary frequency control
    • 40 MW for primary frequency control
  • a wind park with a max power of 300 MW,
  • a hydro plant providing:
    • 50 MW base load using a river turbine
    • +-25 MW pumping power to support the day/night load cycle
    • up to 200 MW peak power on demand.

The following switches/features are provided:

  • powerPlant.Modakond: enhance the frequency/power control of the power plant to reduce throttle losses by utilizing condensate stop (see powerPlant.hotwellLevel.y, powerPlant.throttleReserve.y, powerPlant.pressureLoss.y, powerPlant.throttleCosts.y)
  • windForm.cut_off: suddenly take off the wind farm as the wind speed exceeds the cut-off speed, e.g. in case of a storm
