Coupled CFD-MBD numerical modeling of a mechanically coupled WEC array [PDF]

Ocean Engineering, 2022
The development of new wave energy devices (WECs) has continued unabated over the past decades. For large-scale applications, integrating individual WEC into an array system (WEC net) requires considerable expertise and research due to its highly complex and interrelated nature.

Assessment of the Power Output of a Two-Array Clustered WEC Farm Using a BEM Solver Coupling and a Wave-Propagation Model

Energies, 2018
One of the key challenges in designing a Wave Energy Converter (WEC) farm is geometrical layout, as WECs hydrodynamically interact with one another. WEC positioning impacts both the power output of a given wave-energy project and any potential effects on

Wave-to-Wire Modelling and Hydraulic Pto Optimization of a Dense Point Absorber Wec Array

Renewable Energy
We investigate the hydrodynamic interactions and power extraction efficiency of a dense array of Point Absorber (PA) Wave Energy Converters (WECs) clustered around the fixed pillar of a wind turbine –the Ocean Grazer device– with a standard hydraulic Power Take-Off (PTO) system. Using potential flow theory, a detailed wave-to-wire model is developed in

Impact of Structural Heterogeneities in Hierarchically Grown Microribbons on 2D WS₂ Monolayer on the Measured Local Hydrogen Evolution Activity on Au Substrate. [PDF]

Small
Spatially resolved SECCM measurements reveal that hierarchically grown microribbons on 2D WS2 drastically suppress local HER activity. Relative to the basal plane of the 2D monolayer directly supported on an Au substrate, single‐layer and multilayer microribbons exhibit more than a ∼5‐fold and >10‐fold decrease in current density, respectively.

Predictive Control for a Wave-Energy Converter Array Based on an Interconnected Model

Journal of Marine Science and Engineering, 2022
This paper proposes a model predictive control (MPC) method based on an interconnected model to maximize the ocean wave energy extracted by a wave-energy converter (WEC) array. In the proposed method, a formally uniform interconnected model is applied to

Design and Research of Slope-Pendulum Wave Energy Conversion Device

Journal of Marine Science and Engineering, 2022
Wave energy is a kind of clean energy that is rich in reserves and has not been exploited on a large scale. The slope-pendulum wave energy conversion (S-PWEC) device has been optimized in structure and its capture efficiency has been increased.

Robust optimization of control parameters for WEC arrays using stochastic methods

Journal of Computational Physics, 2023
This work presents a new computational optimization framework for the robust control of parks of Wave Energy Converters (WEC) in irregular waves. The power of WEC parks is maximized with respect to the individual control damping and stiffness coefficients of each device.

Design and Analysis of a Mooring Buoy for a Floating Arrayed WEC Platform [PDF]

Processes, 2021
This paper presents the design and analysis of a mooring buoy and its mooring systems to moor a floating platform mounting an arrayed Wave Energy Converters (WECs). The mooring buoy allows the WEC platform to weathervane around the mooring buoy freely by the prevailing environment directions, which enables consistent power generation.
