Optimization of wind‐wave hybrid system based on wind‐wave coupling model

IET Renewable Power Generation, Volume 18, Issue 8, Page 1407-1427, 8 June 2024.
This study proposes an optimization method based on a wind‐wave coupling model, and takes a new wind‐wave hybrid system as an example for verification and analysis. The results show that the non‐parametric prediction model established in this paper has high accuracy and is used with the NSGA‐II optimization algorithm to effectively improve the wind ...

Oscillating body wave energy conversion efficiency based on Simulink simulation training

Energy Science &Engineering, Volume 12, Issue 4, Page 1411-1421, April 2024.
The wave energy conversion efficiency has been calculated based on Simulink simulation training, and a maximum output power of 8.1 W has been gained as the corresponding linear damping is 21,000 N s/m. Abstract With the development of the economy and society, we are faced with the dual challenges of energy demands and environmental pollution. As one of

Adaptive second order sliding mode control of an oscillating water column

IET Renewable Power Generation, Volume 18, Issue 2, Page 226-237, 3 February 2024.
The proposed adaptive second‐order sliding mode controller maximises energy capture from the waves. In particular, the proposed adaptive control setup maintains the sliding mode robust features, while reducing high frequency oscillations and abrupt control actions produced by fixed‐gain algorithms.
