… When designing “multi-MW arrays” of Wave Energy Converters (WECs), having a low number of converters with high individual power ratings can be beneficial as the Operation and Maintenance (O&M) costs may be reduced. However, having converters of small dimensions or small power ratings could also be beneficial, as suggested by previous …

… (WECs) to model WEC arrays; it is simply correctly defining the geometric layout and degrees-of-freedom. Indeed, these multiple degree-of-freedom array models are the most common method used for modelling WEC arrays. However, in … important to recognize that the computational effort increases approximately with the square of the number of degrees-of-freedom. In addition, in a WEC array model it is also important to …

… Thermal cycling is one of the major reasons for failure in power electronic converters. For submerged tidal turbine … this failure mode is critical in improving the reliability, and minimizing the cost of energy from tidal turbines. This paper considers a submerged tidal turbine converter which is … and where turbines are mostly pitch controlled. The main goal is to quantify the impact of surface waves and turbulence in tidal stream velocity on the lifetime of the converter IGBT …

… options for marine energy converter (MEC) farms. On the technical front, the feasibility of the transmission options considering supply quality constraints and the optimal sizing of reactive power compensation to allow maximum real power transfer capability in the subsea transmission cable have been considered. The economic viability of different transmission options are measured based on component costs and the costs associated …
