"Comparison of wave-body interaction modelling methods for the study of reactively controlled point absorber wave energy converter"


Seminar Abstract:

Wave energy converter (WEC) devices are being developed to enable capture of energy from ocean waves. It showed that WEC reactive control can increase significantly wave power extraction for a point-absorber type WEC. Majority of the WEC reactive control studies used linear potential flow theory and Cummins equation as the basis for modelling hydrodynamics arising from wave-body interaction, which is essential for the implementation of control simulation as well as for the formulation of model-based
control strategies. However, the fidelity of the above mentioned linear approach was questionable and the influences of nonlinear hydrodynamics to the WEC reactive control problem were poorly understood. This study aims to address these concerns by conducting a comparison study on the available wave-body interaction modelling methods (e.g. ranging from the linear approach to the nonlinear ones) and quantifying their fidelity in solving the reactive control problem of a submerged point-absorber (PA) WEC. The longer term goal of the study is to develop computationally efficient surrogate model capturing important nonlinearities for general WEC study and to develop advanced nonlinear control strategies. This talk will present some of the preliminary results obtained at LHEEA, ECN.
