Direct‐Drive wave energy conversion with linear generator: A review of research status and challenges

IET Renewable Power Generation, Volume 17, Issue 4, Page 1020-1034, 16 March 2023., 2023
Abstract Ocean wave energy is sustainable and renewable energy, wave energy conversion (WEC) effectively solves the disadvantage of traditional power system with fossil energy. WEC system is the power generation process that converts wave kinetic energy of undulation and swing into electric energy, and direct‐drive WEC system (D‐DWEC) converts wave ...

Fuzzy Airflow‐Based Active Structural Control of Integrated Oscillating Water Columns for the Enhancement of Floating Offshore Wind Turbine Stabilization

International Journal of Energy Research, Volume 2023, Issue 1, 2023., 2023
This paper presents the modeling and stabilization of a floating offshore wind turbine (FOWT) using oscillating water columns (OWCs) as active structural control. The novel concept of this work is to design a new FOWT platform using the ITI Energy barge with incorporated OWCs at opposite sides of the tower, in order to alleviate the unwanted system ...

Hybrid Renewable Power Generation for Modeling and Controlling the Battery Storage Photovoltaic System

International Journal of Photoenergy, Volume 2022, Issue 1, 2022., 2022
A major portion of the global energy demand was likely to be fulfilled by an extensive supply of renewable power. Renewable energy outputs, on the other hand, are changeable due to the dynamic nature of their sources. The integration of these variable sources of power into current power grids is proving difficult for electrical power system operators ...
