In a significant leap for the renewable energy sector, a new study led by Abderrahmane Redouane from the Faculté de Technologie at the Université de Bejaia introduces an innovative approach to hybrid renewable energy systems (HRESs). Published in the journal ‘Results in Engineering,’ this research highlights the integration of a Vernier Doubly Salient Permanent Magnet Generator (V-DSPMG) into a grid-connected system that harnesses solar energy, wind energy, and battery storage.
The V-DSPMG stands out from traditional wind turbine systems by utilizing a direct-drive mechanism, eliminating the gearbox. This design choice not only enhances the efficiency of wind power generation but also reduces maintenance costs and potential points of failure. “By directly coupling the generator shaft to the turbine shaft, we can maximize energy extraction from wind, leading to more reliable and sustainable energy production,” Redouane explains.
The research employs advanced control algorithms to optimize energy output. A sliding mode control maximum power point tracking (MPPT) algorithm, based on a constant plus proportional rate reaching law, is utilized for the wind turbine, while the photovoltaic system benefits from a perturb and observe (P&O) MPPT algorithm. This dual approach ensures that each energy source operates at peak efficiency, a critical factor for commercial viability in an increasingly competitive energy market.
Moreover, the study introduces a new super-twisting sliding mode control (NSTSMC) method designed to regulate the DC-Link voltage, which is pivotal for maintaining system stability. In comparison with traditional control methods, the NSTSMC demonstrates superior performance, promising enhanced reliability in energy delivery to the grid.
A five-level Active Neutral Point Clamped (5L-ANPC) DC/AC converter is also proposed, which offers improved power quality and a better output voltage harmonic spectrum. This technological advancement is crucial as energy providers strive to meet stringent regulatory standards for grid integration.
The implications of this research extend beyond technical advancements; they signal a shift toward more resilient energy systems capable of autonomously balancing power demands. “This interconnected and supportive arrangement amplifies the system’s reliability and sustainability, making it a model for future hybrid renewable energy systems,” Redouane notes, emphasizing the potential for widespread commercial application.
As the energy sector grapples with the challenges of climate change and the need for sustainable solutions, this innovative hybrid system could serve as a blueprint for future developments. The combination of diverse energy sources, cutting-edge control mechanisms, and enhanced system reliability positions this research at the forefront of renewable energy technology.
