Gaussian Distribution-Based Inertial Control of Wind Turbine Generators for Fast Frequency Response in Low Inertia Systems (2022)
Journal Article
Kheshti, M., Lin, S., Zhao, X., Ding, L., Yin, M., & Terzija, V. (2022). Gaussian Distribution-Based Inertial Control of Wind Turbine Generators for Fast Frequency Response in Low Inertia Systems. IEEE Transactions on Sustainable Energy, https://doi.org/10.1109/tste.2022.3168778

Decline of rotating inertia due to the high share of renewable sources cause challenges in controlling grid frequency. With recent grid codes, large-scale wind turbines (WTs) are required to provide frequency support. Existing stepwise inertial contr...

Tidal Turbine Benchmarking Exercise: Environmental Characterisation and Geometry Specification (2022)
Presentation / Conference Contribution
Tucker Harvey, S. W., Chen, X., Rowe, D., Bhavsar, K., Allsop, T., Gilbert, J., Stallard, T., Vogel, C. R., & Willden, R. H. J. (2021, September). Tidal Turbine Benchmarking Exercise: Environmental Characterisation and Geometry Specification. Presented at European Wave and Tidal Energy Conference (EWTEC) 2021, Plymouth, UK

Uncertainty in tidal turbine loading contributes significantly to conservatism in turbine design. This uncertainty originates not only from a lack of knowledge of the flow field at a particular site, but also from lack of understanding of the fundame...

Observer-Based Unknown Input Estimator of Wave Excitation Force for a Wave Energy Converter (2019)
Journal Article
Abdelrahman, M., & Patton, R. (2020). Observer-Based Unknown Input Estimator of Wave Excitation Force for a Wave Energy Converter. IEEE Transactions on Control Systems Technology, 28(6), 2665-2672. https://doi.org/10.1109/TCST.2019.2944329

Several energy maximization control approaches for point-absorber wave-energy converter (PAWEC) systems require knowledge of the wave excitation force (WEF) that is not measurable during the PAWEC operation. Many WEF estimators have been proposed bas... Read More about Observer-Based Unknown Input Estimator of Wave Excitation Force for a Wave Energy Converter.
