Influence of Buoyancy Control Performance on Power Production by the Wave Dragon Nissum Bredning Prototype

This paper reports on the real sea performance of the buoyancy control system of Wave Dragon, a floating wave energy converter using the overtopping principle. The device operates with the full independent control system which has been tested during three years of operation. The impact of the buoyancy control system performance on the power production is noted. This provides motivation and a target for improved control algorithms
