The session focuses on conversion systems for wind turbines based on power electronics, mainly for off-shore applications. The trend of higher power brings several challenges related to compliance with grid requirements. Harmonics and resonances become crucial issues that require proper analysis and innovative yet practical solutions. This session covers aspects related to power converter architectures and the modulation and control of the converter. We will look at the interaction with the electrical grid as well as practical aspects about how to optimise the primary control in different wind conditions and how to effectively test the control of large-scale wind systems in emulated conditions.
