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
