Wind Energy

Estimation of the energy potential of a location with a view to calculating the possible long-term production foreseen, including: measurements, data processing, simulation, analysis, optimisation, uncertainty analysis and class assessment.

To achieve this, apart from the study approach using traditional WASP methodology, CENER has its own methodology based on CFD and advanced measurement equipment, such as LIDAR, to improve the quality and precision of the complex terrain results. In addition, CENER has methodology to prepare regional maps of the wind resource based on mesoscale models.

The services in this area could be classified, therefore into:

Energy assessment of wind farm locations

These studies include all the necessary aspects to characterise and take maximum advantage of the wind potential of an area:

Identification and search for locations.
Planning and execution of personalised campaigns
Data analysis and processing
Optimisation and energy calculations
Verification of the adaptation of the wind turbine to the location conditions
Uncertainty analysis

Project audits

This type of services, required by developers and financial institutions, examines the evaluation and analysis of the technical risk associated with wind energy projects. The multidisciplinary team of CENER permits an integral approach to this type of studies, which include the preparation or review of the production hypothesis, adaptation of the wind turbine to the location, verification of the electric design, earth-tapping, foundations, accesses, communications system, etc.

Wind resources assessment courses

These courses are tailor-made for the customer, adapting them to their prior level of knowledge and including practical classes in the handling of specific software such as WAsP.

Wind field and wake study via CFD.

These studies permit a more accurate simulation of the wind field than WAsP type linear models, reducing calculation uncertainties, especially in complex terrain locations.

Vertical profile characterisation via laser anemometry (LIDAR).

This equipment permits studying the vertical profile up to 200 m above ground level without having to install a weather tower.

Preparation of wind resource maps

Resource maps of large areas can be prepared, either based on direct measurements or based on global model data.

Work is carried out in the following R&D lines, among others:

Simulation of the wind field with a fluid dynamics model (CFD), average conditions, turbulence, flow inclination, etc.
Simulation of the effect of wind turbine wake by means of CFD
New statistical models for characterisation of extreme winds
New measurement techniques (LIDAR)

CENER participates in both national and international groups of experts, working on the improvement of wind resources assessment procedures.
