Wave basin testing of hydrodynamic interactions in centralized controlled wave energy converter arrays for irregular short- and long-crested waves

Applied Ocean Research
To increase the total installed capacity, multiple wave energy converters (WECs) will be installed in an array configuration. Within these WEC arrays, hydrodynamic interactions occur and the sea state is modified accordingly. These WECs are equipped with

Techno-Economic Development of WECs [PDF]

, 2016
The successful development process of WECs demands large amounts of time and means. The optimal development trajectory manages to keep these expenses to a minimum while delivering an economically viable product at the end of its development. As related expenses (time and money) increase exponentially with the development stages (TRLs) while flexible ...

A competition for WEC control systems

, 2017
This paper outlines a proposed open competition which will compare energy-maximising controllers for wave energy converters (WECs), both in simulation, and in real time,using a scale device in a tank test situation. To date, a wide variety of WEC control algorithms have been proposed, but have been difficult to compare due to ...
