Control‐Oriented Modelling and Adaptive Parameter Estimation for Hybrid Wind‐Wave Energy Systems

IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.
Different with the traditional hybrid wind‐wave energy system models that are established by using the boundary element method (BEM), devoting to understanding the hydrodynamic responses and performance analysis. This paper proposes a control‐oriented model of the hybrid wind‐wave energy system with the coupled aero‐hydro‐mooring dynamics. The obtained

Simulation, testing and validation of digital displacement hydraulic power take-off for wave energy converters [PDF]

, 2020
Whilst the available global wave power resource is significant at over 2 TW, there has been very little exploitation of it to date for the generation of electricity. This is due in part to the challenge of converting energy from a low speed, high force,

Are We Up to the Best Practices in Forage and Grassland Precision Harvest? A Review

Grass and Forage Science, Volume 80, Issue 1, January-March 2025.
ABSTRACT Grassland and forage crops are a domain where the application of precision agriculture techniques has been less intensive so far, compared to grain crops. This is especially evident in the case of variable yield assessment, the step that prompts the adoption of precision management techniques once farmers are faced by unexpectedly high yield ...

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
