# Wind power

Wind power parks can be coupled to specific busbars. This is done through the file `EFI-VIND.DAT` which is optional. The modelling of wind power is licensed (LTM_MPS_VINDPARKER).

|Note|
|-|
| For each wind power park, all productions weights are accumulated and relative shares for each busbar are computed. If the same busbar is listed several times as connected to a specific wind power park, its weights are accumulated.|
| If a wind power park is not connected to any busbars, the wind power is distributed to busbars in its area according to the relative distribution provided in `EFI-FAST.DAT`.|

## Example complete file

Rows starting with ``CC`` are **comments**.

Text after ``#`` are comments (after specified input as shown below)

```text
CC - File connects wind series for areas with detailed grid
2, 1,               # area number, number of wind series
midtfjellet.V47, 2, # wind series name, number of busbar connections
20008, 0.1,         # busbar and weight
20009, 0.0,         # busbar and weight
3, 1,               # area number, number of wind series

```

The file is on the following format:

```text
For each area with wind power:
    - Header
    - Windseries name and number of connected busbars
    - Busbars and wind distribution
```

For each area with wind power:

## Header

Record format:

```text
<Area number>,<number of wind series>,
```

Example:

```text
2, 1,
```

## Wind series and number of busbars

Record format:

```text
<Wind series name>,<number of busbar connections>,
```
Example:
```text
windseries, 2,
```
## Wind series connections to grid and weight

Record format:

```text
<Busbar>, <weight>,
```
Example:

```text
30014, 0.8,
30015, 0.2,
```
