Ocean renewable wave power is one of the more encouraging inexhaustible energy sources, with potential to be exploited for nearly 337 GW worldwide. However, compared other sources renewables, technologies have not been fully developed, and produced price as competitive that wind or solar technologies. In order commercialise ocean technologies, a wide range optimisation methodologies proposed in...

Commercial wave energy exploitation will be realised by placing multiple converters (WECs) in an array configuration. A point-absorber WEC consists of a floating or submerged body to capture from different directions. This acts as efficient absorber that is also generator. Optimising the layout obtain constructive interference within theoretically beneficial, whereas for wind farms, it only imp...

The topics of zero-emission/energy buildings and electric mobility are increasingly being discussed as solutions to alleviate the environmental burden caused by energy consumption CO2 emissions in both sectors. This study investigates a zero-energy hotel building supported hybrid ocean renewable system, which interacts with several zero-emission boats. Nine different combinations floating photo...

Combining wave energy converters (WECs) with a floating breakwater provides potential approach to help develop commercial-scale power operations. This paper aims design and optimize three-dimensional integrated WEC array by developing numerical model of multi-floating-body coupled system based on flow theory viscous correction in the frequency domain. By analyzing surface elevations around brea...

This paper investigates model predictive control (MPC) of a sea wave energy converter(WEC). A novel objective function is adopted in the MPC design, which brings obvious benefits: First, the quadratic program (QP) derived from this objective function can be easily convexified, which facilitates the employment of existing efficient optimization algorithms. Second, this novel design can trade off...

Ocean wave energy has significant technical potential but limited full-scale deployments and technology convergence. Consequently, guidelines for developing converters (WECs) are still themselves, especially around experimental uncertainty analysis (UA). To develop a comprehensive WEC-specific UA methodology, we conducted 1:30 scale experiment of case study oscillating water column (OWC) WEC. T...

Integrating multi-type Wave Energy Converters (WECs) enables wave energy to be extracted from multiple harvesting manners simultaneously, which presents a more competitive conversion technology. In this study, an Oscillating Water Column (OWC) and Buoy (OB) are combined devise hybrid WEC system that serves as floating breakwater. The two devices aligned in line with the incident direction, wher...

For both the expansion of important islands/reefs and development marine resources in South China Sea, a modular integrated floating structure (MIFS) system with tidal self-adaptation dolphin-fender mooring (DFM) has been proposed. The DFM, coupled wave energy converters (WEC), can serve as an anti-motion system. Considering modules’ hydrodynamic interaction effect connectors’ mechanical coupli...

Scaled model tests are an important step during the research and development of wave energy converters (WECs). While such scaled in physical tanks prone to undesired scaling effects due e.g. mechanical artefacts and/or fluid effects, numerical (NWTs) provide excellent tools for analysis WECs across a range scales, overcoming limitations test environment. Simultaneous based on Froude Reynolds nu...
