# Wind

Wind power plants represent power supplied from the volatile power source of wind power. There are two way the model interpet wind parks depending on whether the "has_cost" field is set for the park. See [logical model documentation](lmwindpark) to see the field name and documentation. 

## Parks without cost

Wind power supply power directly to the power balance, wind power supply within an area is added directly to the right hand side of the power balance equation. Setting up wind power needs an area to set up the wind power in, then creating a [wind park](lmwindpark) in the logical model. More than one wind park may share the same production time series, which can be modified by setting a certain weight series. [See module documentation](modulewind) 

The module itself aggregates the total contribution per area for use in the [load module](moduleload).

## Parks with cost

If the "has_cost" field is set to true, the park needs an additional input. [See module documentation](modulewind) for information about URLS. This additional input is the cost of production for the plant. Internally, these parks are converted into variables similar to market steps with capacity and cost, and is added to the left hand side of the load balance. 

Should any parks have negative costs an extra configuration setting must be set to true. [See module documentation](modulewind) for more information about the config parameter name.

## Result data

Production for each park is added to the result data. [See module documentation](modulewind) for more information about the output series. This result series is created both for plants with and without costs.
