Biography

My major fields of research interests are in the influence of wind conditions and cold climate in the wind turbine operation, performance, and control. I have experience in wind measurements with Lidar, wind resource assessment, power and operational analysis of wind turbine, analysis of wind turbine control, as well as icing, ice detection, and influence of icing in power performance of wind turbine. Additionally, I have experience in identification and control of active magnetic bearings.
