This study presents a complete wave-to-wire model in which a novel wave energy converter control approach based on adaptive vector control is introduced. The proposed control for maximum power absorption of the primary resource is included, as well as the grid interconnection topology and required controllers, needed for processing the power over the entire wave energy conversion chain. Thanks to the adaptive performance of the proposed controller, maximum energy extraction can be instantaneously achieved regardless of the current irregular wave characteristics of the resource. Finally, the proposed electrical configuration arises as a suitable grid interconnection solution, as it not only provides maximum power supply from the wave energy resource, but it also contributes towards further reducing its output power oscillations.
