The DISPATCHES Wind Power Model calculates the electricity production from a wind farm using wind resource data and the PySAM Windpower module. The model assumes a single turbine with a powercurve from the ATB Turbine 2018 Market Average. Wake effects are not modeled, and PySAM's default losses are assumed. The power output of the entire farm of any size is calculated by scaling the output from the single turbine.
The Wind Power Model has 0 degrees of freedom.
The Wind Power Model uses the wind resource data and the single turbine to calculate a capacity_factor that is then used to scale the electricity output of a wind farm of any size. The wind resource data is provided via the ConfigBlock as a resource_probability_density, a probability density function of wind speed [m/s] and wind direction [degrees clockwise from N] indexed by time. The setup_atb_turbine function provides turbine parameters to PySAM and can be modified to simulate a turbine with a different hub height and power curve.
The Wind Power Model uses the following variables:
| Variable Name | Symbol | Notes |
|---|---|---|
| system_capacity | S | |
| capacity_factor | Ct | Parameter determined via PySAM simulation |
| electricity | Et | Electricity to outlet |
Electricity output scales with system_capacity:
Et = S × Ct
