A team of researchers at Khalifa University in the UAE has successfully developed a cutting-edge hybrid renewable energy system that integrates multiple energy sources.
The system combines wind and solar power with hydrogen storage, along with advanced prediction and control technologies, making significant strides in energy efficiency and stability.
The system operates on a hybrid grid that merges wind and solar energy, using a novel two-layer structure.
The first layer focuses on managing hydrogen production and consumption to meet daily energy demands while reducing operational costs. The second layer ensures smooth energy delivery to the grid through an advanced control methodology.
The research team highlighted that their system not only improves the management of hybrid microgrids but also meets energy needs more efficiently.
It enhances economic performance by minimising power fluctuations and optimising the operational states of hydrogen devices compared to conventional control methods. Their work involved extensive numerical simulations and laboratory tests at Khalifa University’s Energy Systems and Control Optimization (ESCO) Lab.
The control strategy represents is a leap forward in hybrid grid management. By integrating hydrogen energy storage with advanced predictive and control models, the system improves the efficiency and stability of renewable energy sources, contributing to a more reliable and sustainable energy future.
The research team included Dr. Mohamed Bakr Abdelghani, Professor Ahmed Al-Durra, and Professor Hatem Zein El-Din, in collaboration with Professor Fei Gao from the University of Belfort Montbéliard Technology in France.
Their findings were published in IEEE Transactions on Industrial Informatics.
Hydrogen energy storage, which plays a central role in this system, is highlighted for its long-duration storage capacity and ability to stabilise fluctuating renewable energy sources.
