How to maximize wave power capture of viwec array?

For maximising the wave power capture of the VIWEC array, a centralised NMPC strategy is proposed and implemented by AC/DC converters with the SVPWM technique.

Is a wave-to-wire wave energy converter array suitable for stand-alone offshore applications?

This paper develops a wave-to-wire model of a vibro-impact wave energy converter array for stand-alone offshore applications. Nonlinear model predictive control is proposed for maximising the wave power capture of the array, and implemented by AC/DC converters and the space vector pulse width modulation technique.

Why is a wave energy maximisation test important?

It is valuable for evaluating the performance of array deployment, wave energy maximisation control, energy storage system, and power management strategy. (ii) For the VIWEC array, the occurrence of constructive and deconstructive effects mainly depends on the WEC separation distance and incident wave direction.

Why do we need a wave energy system?

The periods of ocean waves fluctuate between 5 s and 20 s. Thus, designing a WEC capable of operating efficiently across varying sea states while providing a stable power supply to end-users remains a significant challenge . Since wave energy technology is immature, WECs are generally expensive to install, operate, maintain and decommission.

Do NMPC and power management strategies work in a W2W array?

By integrating the NMPC and power management strategies into the W2W model of the VIWEC array, this study not only maximises wave energy capture and stabilises output power but also addresses key challenges in control strategies for WEC arrays.

What is the difference between a viwec array and a mechanical power output?

In contrast to the mechanical power output of an individual VIWEC, the VIWEC array demonstrates a noticeable reduction in maximum error across all three wave directions. The maximum error is generally the lowest at , with more than a 50 % reduction at certain separation distances.
