Layout of wind turbine generator set

What are the trends in wind turbine design & layout optimization?

The trends are similar to the smaller, circular wind farm. Coupled turbine design and layout optimization is superior to optimizing each sequentially, especially for the smaller wind farms where the wind speeds are much lower than the free stream.

How do turbine design and layout optimization affect a wind farm?

However, the average wind speed in a farm is dependent on the turbine layout, making it difficult to choose the correct speed for which to design the turbines. Thus, is important to couple the turbine design and layout optimization for a superior wind farm.

How to optimize a wind turbine design in a training wind farm?

The first is to consider sequential optimization in which the turbine design is not optimized in isolation but for the baseline turbine layout in a sort of “training wind farm”.

Should a wind farm have two different turbine designs?

Including two different turbine designs in the same wind farm can be very beneficial in reducing wake interference between wind turbines and result in a lower COE compared to a farm with all identical wind turbines. For wind turbines that are close together, wake interactions are very strong between turbines.

How do I choose the best wind farm layout?

The space of a wind farm is constrained, so for all realistic wind roses, any turbine layout will have some wind turbines that are waked or partially waked some or all of the time. Therefore, to find the best layout often nonobvious trade-offs must be made to minimize wake interactions throughout the entire farm.

How can a gradient-based optimization framework solve wind turbine layout design parameters?

We introduced an iterative gradient-based optimization framework to simultaneously solve for the layout design parameters and wind turbine operation parameters. The wind farm design was specified by the mooring system parameters and the neutral positions of each turbine.
