Book Synopsis Numerical Modelling of Wave Energy Converters by : Matt Folley
Download or read book Numerical Modelling of Wave Energy Converters written by Matt Folley. This book was released on 2016-06-14. Available in PDF, EPUB and Kindle. Book excerpt: Numerical Modelling of Wave Energy Converters: State-of-the Art Techniques for Single WEC and Converter Arrays presents all the information and techniques required for the numerical modelling of a wave energy converter together with a comparative review of the different available techniques. The authors provide clear details on the subject and guidance on its use for WEC design, covering topics such as boundary element methods, frequency domain models, spectral domain models, time domain models, non linear potential flow models, CFD models, semi analytical models, phase resolving wave propagation models, phase averaging wave propagation models, parametric design and control optimization, mean annual energy yield, hydrodynamic loads assessment, and environmental impact assessment. Each chapter starts by defining the fundamental principles underlying the numerical modelling technique and finishes with a discussion of the technique's limitations and a summary of the main points in the chapter. The contents of the chapters are not limited to a description of the mathematics, but also include details and discussion of the current available tools, examples available in the literature, and verification, validation, and computational requirements. In this way, the key points of each modelling technique can be identified without having to get deeply involved in the mathematical representation that is at the core of each chapter. The book is separated into four parts. The first two parts deal with modelling single wave energy converters; the third part considers the modelling of arrays; and the final part looks at the application of the different modelling techniques to the four most common uses of numerical models. It is ideal for graduate engineers and scientists interested in numerical modelling of wave energy converters, and decision-makers who must review different modelling techniques and assess their suitability and output. - Consolidates in one volume information and techniques for the numerical modelling of wave energy converters and converter arrays, which has, up until now, been spread around multiple academic journals and conference proceedings making it difficult to access - Presents a comparative review of the different numerical modelling techniques applied to wave energy converters, discussing their limitations, current available tools, examples, and verification, validation, and computational requirements - Includes practical examples and simulations available for download at the book's companion website - Identifies key points of each modelling technique without getting deeply involved in the mathematical representation

Book Synopsis PASSIVITY-BASED NUMERICAL MODELING AND GRID INTEGRATION STRATEGIES FOR WAVE ENERGY CONVERTER ARRAYS by :
Download or read book PASSIVITY-BASED NUMERICAL MODELING AND GRID INTEGRATION STRATEGIES FOR WAVE ENERGY CONVERTER ARRAYS written by . This book was released on 2022. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : The body of work presented here develops numerical time-domain models of Wave Energy Converter (WEC) arrays or wave farms. It will be shown here that a cluster of WECs can be more effective in extracting oceanic energy, can facilitate deployment logistics, and help with grid integration. The objectives of this work are: (i) developing a theoretical metric to evaluate the energy extraction potential of a WEC array, (ii) developing an algorithm that ensures the stability of the time-domain models of WEC arrays, and (iii) identifying strategies that facilitate grid integration and power management of a WEC array. In the process of developing the theoretical performance metric, the potential theory was used to develop expressions for wave potentials as the incoming wave reflects by and transmits through the WEC array. Decomposing the wave potential in horizontal and vertical parts enabled the application of boundary conditions based on continuity in terms of velocities and potentials. Incorporation of the hydrodynamic terms showed an increase of up to 28% in the low-frequency range. The knowledge of the wave potentials in and around the WEC array helped the application of robust system identification strategies that accurately described the physical phenomenon and ensured the numerical stability of the numerical models. The dissipative nature of the system enabled the application of the passivity property for system identification. The proposed approach could guarantee the numerical stability of time-domain modeling of WEC arrays while also ensuring high accuracy of the emulated hydrodynamics and the motions of the bodies. For the case studies considered, the identified systems calculated the motion time-histories with > 95% accuracy for WEC array cases and > 99% accuracy for the single isolated body case. Finally, the dissertation addresses the grid integration and power management issues associated with the power generated by WEC arrays. The oscillatory nature of ocean waves introduces variability in the total power produced. This work develops the conditions that exploit the phase offsets in the wave received at individual WECs at any given time. The conditions developed here will result in constant power by imposing polyphase power profiles for the WECs in the array. Continuously constant power is desirable for grid integration and power management. Additionally, the objectives for an ideal power controller are developed that can make the overall produced by the WEC array constant. 95% accuracy for WEC array cases and > 99% accuracy for the single isolated body case.
