The OPTIMIZE module offers a variety of different methods, which can be used for wind farm optimisation, including generating geometrical and random wind farm layouts.

  • Flexible Optimization Model
    Optimize multiple, different areas with various options and input-models like WAsP, WAsP-CFD or other CFD models.
  • Regular Pattern Layout
    Optimize geometrically shaped park layouts (e.g an in arc), adhering to angles, distances, row offsets etc.
  • Irregular Pattern Layout
    Optimize park layouts maximizing AEP without adhering to a pre-defined pattern.
  • Noise Reduction Optimization
    Optimize operation modes to adhere to noise regulations, minimizing lost production.
  • Fill Area
    Insert the maximum number of turbines possible with a defined minimum spacing.
  • Report
    Generate a report containing results, maps, wind resources etc.

OPTIMZE Flexible models

Flexible optimization model

For energy optimization, the calculation is based on a pre-calculated wind resource map from WAsP, WAsP-CFD or another CFD model. The available land for the wind farm is digitized or loaded from GIS and within this area the optimization takes place. Different modes of optimizations are possible: gradual addition of turbines, incremental change of geometric layouts, filling up the land with maximum number of turbines or optimization of noise operation modes in a fixed layout. The calculation models are developed by EMD.

OPTIMIZE Regular Patterns

Regular Pattern Layouts

Design parks with strict requirements to a geometrical layout, e.g. straight parallel lines with equal distances between the WTGs or e.g. offshore, but also arc layouts can be handled. windPRO automatically tests a matrix of parameters such as angles, distances, row offsets to find the optimal layout of the wind farm. This is particularly useful for off-shore wind farms.

OPTIMIZE Irregular Patterns

Irregular layouts

The optimizer gradually adds turbines to the layout on the best location available keeping the already placed turbines optimal until the requires number is reached or no more turbines can be placed.

Fill area

The optimizer automatically packs an area with turbines keeping the specified spacing between turbines.

Noise optimization

Optimize the selected noise operation mode of a specified layout to get the minimum loss of production. If the wind farm cannot comply with noise limits even at the lowest settings the most problematic turbines will be removed until the wind farm complies with the noise requirements.


Calculation Report

The resulting optimized layout can be used by all windPRO modules, please see the respective module descriptions for details. It is possible to print maps with wind resources, wind farm areas and the resulting layout together.

The WTG Area Object:

One or more WTG areas are digitized on the screen. For each partial area specific requirements as number of WTGs and/or installed capacity can be entered together with required minimum distances between the WTGs. The WTG Area Object can also define restriction zones where turbines cannot be placed, such as road, lakes, built-up areas and otherwise protected land including an identification of terrain too steep for wind turbines. A buffer zone can be defined to account for a minimum distance to keep to the delimitations of either exclusion zones or WTG areas.

Wind Data Input:

Normally, a pre-calculated wind resource map is required for the area in order to carry out the automatic optimization. However, for areas with simple and uniform wind conditions, e.g. for offshore projects, a simple wind distribution can be used.

WTG type(s):

A WTG type can be selected from the WTG catalogue. It is also possible to define different WTG types in different project areas before starting the optimization in order to allow an optimization of areas with different WTGs. Existing WTGs can be included in the calculations. Each turbine type may have several noise operation modes for which power curves can be selected. This is used to optimize the noise operation settings.

The module includes Park Design – a tool for fully geometrical wind farm layout with interactive control of design requirements for the wind farm area.
