“…There are two types of PTO systems in OBs: hydraulic and direct-drive PTO systems. The hydraulic PTO scheme is widely applied because of its high energy transmission efficiency, simple structure, and strong controllability [95]. A typical hydraulic wave energy PTO system, illustrated in Figure 6, consists of a hydraulic cylinder, hydraulic pipelines, There are two types of PTO systems in OBs: hydraulic and direct-drive PTO systems.…”

Based on the mutual compensation of offshore wind energy and wave energy, a hybrid wind–wave power generation system can provide a highly cost-effective solution to the increasing demands for offshore power. To provide comprehensive guidance for future research, this study reviews the energy conversion and coupling technologies of existing hybrid Wind–wave power generation systems which have not been reported in previous publications. The working principles of various wind and wave energy conversion technologies are summarised in detail. In addition, existing energy coupling technologies are specifically classified and described. All aforementioned technologies are comprehensively compared and discussed. Technological gaps are highlighted, and future development forecasts are proposed. It is found that the integration of hydraulic wind turbines and oscillating wave energy converters is the most promising choice for hybrid wind–wave power extraction. DC and hydraulic coupling are expected to become mainstream energy coupling schemes in the future. Currently, the main technological gaps include short their operating life, low energy production, limited economic viability, and the scarcity of theoretical research and experimental tests. The field offers significant opportunities for expansion and innovation.

“…Compared to other algorithms, such as the PSO, GWO, WOA, and CMA-ES, they determined that the enhanced MFO algorithms performed the best. Neshat et al (2022) [126] conducted an additional study on the WEC layout optimization using a unique multi-swarm cooperative method with a backtracking technique. The suggested method by these researchers is oriented toward resolving the challenges associated with optimizing the placement of WECs in a wave farm.…”

“…Second, the converter may experience unexpected forces that increase or decrease its displacement, velocity, or acceleration, due to the unforeseen changes in the WEC's position aquaculture. Research on optimizing the PTO settings or control strategy coefficients has recently been conducted [139]. In Figure 9, a hydraulic PTO (HPTO) of a two-body point absorber is illustrated, which recently was the main focus of several types of research.…”

The Optimal Configuration of Wave Energy Conversions Respective to the Nearshore Wave Energy Potential

et al. 2022

View full text Add to dashboard Cite

Ocean energy is one potential renewable energy alternative to fossil fuels that has a more significant power generation due to its better predictability and availability. In order to harness this source, wave energy converters (WECs) have been devised and used over the past several years to generate as much energy and power as is feasible. While it is possible to install these devices in both nearshore and offshore areas, nearshore sites are more appropriate places since more severe weather occurs offshore. Determining the optimal location might be challenging when dealing with sites along the coast since they often have varying capacities for energy production. Constructing wave farms requires determining the appropriate location for WECs, which may lead us to its correct and optimum design. The WEC size, shape, and layout are factors that must be considered for installing these devices. Therefore, this review aims to explain the methodologies, advancements, and effective hydrodynamic parameters that may be used to discover the optimal configuration of WECs in nearshore locations using evolutionary algorithms (EAs).

“…In recent years, inventors have become interested in wave converters. Since 1980, about 1000 patents have been registered on this topic, which is still increasing rapidly [5]. In 1799, Girard invented the first wave converter, like today's converters in France [6], known as one of the first converters.…”

This study proposes a data-driven methodology for modeling power and hydrogen generation of a sustainable energy converter. The wave and hydrogen production at different wave heights and wind speeds are predicted. Furthermore, this research emphasizes and encourages the possibility of extracting hydrogen from ocean waves. By using the extracted data from FLOW-3D software simulation and the experimental data from the special test in the ocean, the comparison analysis of two data-driven learning methods is conducted. The results show that the amount of hydrogen production is propor-tional to the amount of generated electrical power. The reliability of the proposed renewable energy converter is further discussed as a sustainable smart grid application.
