Iberdrola chooses supercomputers to design projects

SPAIN: Iberdrola has designed a wind plant using a computational model; a tool the company plans to use from now on, both onshore and offshore.

The completed design — for the 66MW Puebla-Pier II project in Mexico — marks the culmination of a three and a half year research and development programme called Sedar.

Iberdrola claims Sedar will substantially improve the calculation of wind-power output across a wind farm's lifecycle and overcome the obstacles determining the exact location of the best wind resources at complex sites.

Sedar was developed in conjunction with the Barcelona Supercomputing Centre (BSC), with the support of Spain's National Renewable Energy Center (CENER). It uses BSC's MareNostrum supercomputer, "the most powerful in Spain", according to Iberdrola.

It is claimed the model can provide wind simulation at a high-resolution scale measured in square meters, rather than tens of square meters as in the case of other existing models. It also predicts stress and fatigue on turbines from turbulence and cross winds.

Other computerised versions at the complex Puebla-Pier II site could not provide accurate enough measurements, even after installing 15 wind measuring masts, according to a recent statement from José María Cela, BSC's applications director. With Sedar, five masts would have been enough for accurate modelling, he claimed.
