Offshore and complex terrain wind farms testing

Fig. 1: Danish Offshore wind farm.

We have been working in models to carry out simulation of wind farms. The crux point to simulate farms is to be able to depict the wake perfectly. We have managed to track the wake by means of using the Actuator Line Method [1].

The implementation of the Actuator Line Method (ALM) in CTTC’s code has been done carefully, aiming at a flexible and general code. Thus, the version of the implemented ALM may be used in cases with different layouts such as one, two or tens of turbines in simple or complex terrain.

 

Regarding offshore technology, note that:

  • The ALM is perfectly compatible with an swinging offshore wind turbine as described in the previous section (see video 1).
  • CTTC has been involved in an european project called OffWindTech, under the leadership of the European Institute of Innovation & Technology, described in the previous section.
