… 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 …

… for marine energy are to reduce carbon emissions, and improve security and sustainability of supply. There are other technologies that also meet these requirements, and therefore the … and infrastructure. This will be used to identify scenarios where wave energy forms part of the least-cost energy system for the UK by 2050, and will assess what LCOE reductions are …

… 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 …
