Brandetti, L. (author), Mulders, S.P. (author), Merino Martinez, R. (author), Watson, S.J. (author), van Wingerden, J.W. (author)Vertical-axis wind turbines (VAWTs) are considered promising solutions for urban wind energy generation due to their design, low maintenance costs, and reduced noise and visual impact compared to horizontal-axis wind turbines (HAWTs). However, deploying these turbines close to densely populated urban areas often triggers considerable local...review 2024

Brandetti, L. (author), Mulders, S.P. (author), Liu, Y. (author), Watson, S.J. (author), van Wingerden, J.W. (author)The combined wind speed estimator and tip-speed ratio (WSE–TSR) tracking wind turbine control scheme has seen recent and increased traction from the wind industry. The modern control scheme provides a flexible trade-off between power and load objectives. On the other hand, the Kω2 controller is often used based on its simplicity and steady-state...journal article 2023

Unscented Kalman filter-based blade-effective wind speed estimation for a vertical-axis wind turbineBrandetti, L. (author), Liu, Y. (author), Pamososuryo, A.K. (author), Mulders, S.P. (author), Watson, S.J. (author), van Wingerden, J.W. (author)On-shore horizontal-axis wind turbines (HAWTs) provide a cost-effective solution for low carbon electricity generation. However, public acceptance is still a problem. A possible alternative to a HAWT is a vertical-axis wind turbine (VAWT), which is more visually appealing and less noisy. Furthermore, the inherent omni-directionality of VAWTs...journal article 2023

Brandetti, L. (author), Liu, Y. (author), Mulders, S.P. (author), Ferreira, Carlos (author), Watson, S.J. (author), van Wingerden, J.W. (author)In recent years, industrial controllers for modern wind turbines have been designed as a combined wind speed estimator and tip-speed ratio (WSE-TSR) tracking control scheme. In contrast to the conventional and widely used Kω 2 torque control strategy, the WSE-TSR scheme provides flexibility in terms of controller responsiveness and...journal article 2022
