A Survey of WEC Reliability, Survival and Design Practices

open access: yesEnergies, 2017
A wave energy converter must be designed to survive and function efficiently, often in highly energetic ocean environments. This represents a challenging engineering problem, comprising systematic failure mode analysis, environmental characterization ...

Robust control of wave energy converters [PDF]

open access: yes2014 IEEE Conference on Control Applications (CCA), 2014
Energy-maximising controllers for wave energy devices are normally based on linear hydrodynamic device models. Such models ignore nonlinear effects which typically manifest themselves for large device motion (typical in this application) and may also include other modelling errors. In this paper, we present a methodology for reducing the sensitivity to

Far-Field Maximal Power Absorption of a Bulging Cylindrical Wave Energy Converter

open access: yesEnergies, 2020
The maximal power that is absorbed by a wave energy converter can be estimated from the far-field behavior of the waves that are radiated by the device.

Comments on Control of Wave Energy Converters

open access: yesIEEE Transactions on Control Systems Technology, 2021
The main objective of this letter is to consolidate the knowledge about the dynamics and control of oscillating-body wave energy converters (WECs). A number of studies have shown that control systems strongly affect power absorption; however, there remains a need for a concise and integrated explanation of the theoretical and practical implications ...

Adaptive Control of a Wave Energy Converter [PDF]

open access: yesIEEE Transactions on Sustainable Energy, 2018
Energy maximizing controllers (EMCs), for wave energy converters (WECs), based on linear models, are attractive in terms of simplicity and computation. However, such (Cummins equation) models are normally built around the still water level as an equilibrium point and assume small movement, leading to poor model validity for realistic WEC motions ...

Generating The Electrical Energy from Sea Waves [PDF]

open access: yesJournal of Soil Sciences and Agricultural Engineering, 2019
The wide coverage and the untapped tremendous energy amount stored by the oceans makes the harness of ocean waves for electricity-generating is promising. Most techniques of wave energy converters (WECs) include a pneumatic or hydraulic interface between

Efficiency analysis of the cycloidal wave energy convertor under real-time dynamic control using a 3D radiation model

open access: yesInternational Marine Energy Journal, 2022
Ocean waves provide a vast, uninterrupted resource of renewable energy collocated around large coastal population centers. Clean energy from ocean waves can contribute to the local electrical grid without the need for long-term electrical storage, yet ...

On the capture width of wave energy converters [PDF]

open access: yesApplied Ocean Research, 2009
This paper extends the theory on capture width, a commonly used performance indicator for a wave energy converter (WEC). The capture width of a linear WEC is shown to depend on two properties: the spectral power fraction (a property introduced in this paper), which depends entirely on the sea state, and the monochromatic capture width, which is ...

Design optimization of ocean renewable energy converter using a combined Bi-level metaheuristic approach

open access: yesEnergy Conversion and Management: X, 2023
In recent years, there has been an increasing interest in renewable energies in view of the fact that fossil fuels are the leading cause of catastrophic environmental consequences.
