Inertial response from wind turbines: the impact on structural loads

This works evaluates the impact on structural loads of DFIG wind turbines providing inertial response while operating at rated power. The approach is to use an integrated simulation environment to model the most important electrical, structural, and control dynamics. Estimation of the impact is done in terms of 1-Hz equivalent loads, and maximum-minimum loads.

It is observed that some structural loads are significantly affected. Therefore the trade off between the amount of inertial response and the cost of loads imposed should be assess from an statistical perspective.
