In the heart of Cameroon, researchers are redefining the future of wind energy systems, and their work could have significant implications for the global energy sector. Clotaire Thierry Sanjong Dagang, a researcher at the Applied Automation and Informatics Research Unit (UR_AIA) within the Department of Electrical Engineering at the University of Dschang, has developed a novel control process that promises to make wind power systems more efficient and cost-effective.
Dagang’s research, published in the International Journal of Electrical Power & Energy Systems, focuses on terminal sliding mode control, a sophisticated technique that estimates wind speed and the mechanical rotation speed of permanent magnet synchronous generators (PMSGs). This innovation is a game-changer because it reduces the need for expensive sensors, thereby lowering the overall cost of wind power systems.
“By eliminating the need for tachometric and anemometric sensors, we can significantly reduce the capital expenditure required for wind power installations,” Dagang explains. “This makes wind energy more accessible and competitive in the market.”
The implications of this research are far-reaching. Wind power systems typically rely on a complex array of components, including PMSGs, PWM rectifiers, batteries, DC–DC converters, PWM inverters, and centrifugal pumps driven by asynchronous squirrel-cage machines. Dagang’s control process streamlines this setup, making it more reliable and energy-efficient.
To validate his approach, Dagang conducted extensive simulations using MATLAB Simulink. The results were compared with conventional sliding-mode control methods, which rely on additional sensors. The findings were compelling: Dagang’s terminal sliding mode control demonstrated robust performance, reliable trajectory tracking, and reduced energy consumption.
However, there is a trade-off. The settling time for estimated quantities is slightly longer than when using traditional sensors. But Dagang is optimistic about future improvements. “While the settling time is currently longer, ongoing research and development will likely address this issue, making the system even more efficient,” he says.
The potential commercial impact of this research is substantial. As the world shifts towards renewable energy, the cost and efficiency of wind power systems are critical factors. Dagang’s innovation could make wind energy more viable, particularly in regions where initial investment costs are a significant barrier.
Moreover, the reliability of the proposed estimation algorithm opens up new possibilities for remote and off-grid wind power installations. These systems often face challenges related to maintenance and sensor reliability, and Dagang’s control process could provide a more sustainable solution.
As the energy sector continues to evolve, innovations like Dagang’s terminal sliding mode control will play a crucial role in shaping the future. By making wind power systems more affordable and efficient, this research paves the way for a greener, more sustainable energy landscape. The work, published in the International Journal of Electrical Power & Energy Systems, is a testament to the transformative potential of cutting-edge research in the energy sector.
