Ocean wave energy converters: Technical principle, device realization, and performance evaluation

Multistable vibration energy harvesters: Principle, progress, and perspectives

“…However, the real ocean test is necessary to check the energy harvesting performance and efficiency of the multistable ocean wave energy harvesting system. For large-scale energy harvesting in the real world wave excitation, various non-resonating energy harvesting systems with large output power were designed and tested [104]. For example, Liang et al [105] designed a non-resonating wave energy converter containing a buoy (1.2 m) and a mechanical motion rectifier based power takeoff system.…”

A Review of SPH Techniques for Hydrodynamic Simulations of Ocean Energy Devices

“…Subsequently, by summing up the overall neighboring particles within the support radius of the i-th particle, Equations ( 9), (13), and ( 14) can be rewritten from the continuous form to the discrete form as…”

“…Since the capture and exploitation of ocean energy started to receive attention by the scientific and industrial communities [3], the technologies for harnessing ocean energy have been investigated and developed significantly to meet the energy market, which considerably fosters the invention of diverse Ocean Energy Devices (OEDs) ranging from small-scale isolated apparatus [4] to largescale Integrated Energy Harvesting Systems (IEHSs) [5,6]. Generally speaking, as shown in Figure 1, the classification of OEDs can be mainly categorized by their energy resource, i.e., winds (e.g., Floating Wind Turbines, FWTs) [7][8][9][10], waves (e.g., Wave Energy Converters, WECs) [11][12][13], currents (e.g., Tidal Current Turbines, TCTs) [14][15][16], and multi-resource (see e.g., [6]). As pointed out by Said and Ringwood [17], ordinary OEDs consist of four phases to converting ocean energy to electricity (see also Figure 2), namely, absorption, transmission, generation, and conditioning.…”

Fully Coupled Analysis of an Integrated Floating Wind-Wave Power Generation Platform in Operational Sea-States

“…Meanwhile, offshore wind and wave energies have strong symbiosis, which signifies that abundant wind energies are often accompanied by ample wave energy resources. However, different from the offshore wind energy exploitation, wave energy has not yet been exploited at large commercialized scale as limited by its high construction and maintenance costs, unstable power generation, and low reliability (Zhang et al, 2021). The FOWT technology has been well proven to be a reliable means of exploiting wind power in deep waters, with several commercial floating wind farms being operated in Europe including the Hywind Scotland, WindFloat Atlantic, and Kincardine Scotland projects.…”
