Oscillating body wave energy conversion efficiency based on Simulink simulation training

Energy Science &Engineering, Volume 12, Issue 4, Page 1411-1421, April 2024.
The wave energy conversion efficiency has been calculated based on Simulink simulation training, and a maximum output power of 8.1 W has been gained as the corresponding linear damping is 21,000 N s/m. Abstract With the development of the economy and society, we are faced with the dual challenges of energy demands and environmental pollution. As one of

Combining observed linear basin amplification factors with 1D nonlinear site‐response analyses to predict site response for strong ground motions: Application to Wellington, New Zealand

Earthquake Spectra, Volume 40, Issue 1, Page 143-173, February 2024.
This study develops a method for estimating site amplification that combines instrumentally observed site‐specific amplification factors with adjustment factors from nonlinear site‐response analyses. This approach provides estimates of site response for large‐strain motions based on observations and sophisticated nonlinear modeling.

A Flap-Type Seabed-Mounted Wave Energy Converter With Hydraulic PTO: Analytical Investigation & Experimental Analysis

, 2020
This paper provides a study of a flap-type wave energy converter with a hydraulic power-take-off (PTO) system. This study includes the derivation of its equation of motion along with an analysis of natural frequencies of the device. A prototype was built using fillable cylinders and a series of experiments were performed in a wave flume.

Sail Wind Power Stations: Evaluating the Efficiency of Converting Mechanical Energy into Electrical Energy

International Journal of Energy Research, Volume 2024, Issue 1, 2024.
This study aimed to improve the design of an automatically controlled sail wind power station (SWPS). The peculiarity of the considered SWPS design is that its working body (WB) is rigidly connected to the upper platform of a Sholkor parallel manipulator that has six degrees of freedom.

A Review of Wave-to-Wire Models for Wave Energy Converters

Energies, 2016
Control of wave energy converters (WECs) has been very often limited to hydrodynamic control to absorb the maximum energy possible from ocean waves. This generally ignores or significantly simplifies the performance of real power take-off (PTO) systems ...
