Waves are a promising source of renewable energy. In the last decades, several device concepts have been proposed and studied using different approaches. The modeling and design of wave energy converter parks pose important challenges for both the hydrodynamic and the optimal control communities. From the point of view of hydrodynamics, the possible choices of both mathematical models and methods are many. The most common model is linear potential flow theory. In real applications, however, large displacements and wave steepnesses are encountered. Nonlinear models are needed to treat these cases, for instance when simulating extreme conditions that can impact the device survivability. From the point of view of optimal control, both the positions of bodies within arrays and the control strategies need to be devised, taking into account the variability and uncertainty of the sea state.
