The energy landscape is undergoing a profound transformation, driven by the integration of distributed energy resources and the rise of microgrids. At the forefront of this evolution is a novel approach to optimizing energy efficiency within these systems, as presented by Rajarshi Basu from the Indian Institute of Technology Madras. His recent research, published in ‘IEEE Access’, introduces a groundbreaking loss minimization algorithm specifically designed for the 3-port converter, a technology that promises to enhance the operational efficiency of multi-subgrid microgrids.
Microgrids, which enable localized power generation and consumption, are becoming increasingly vital as the world shifts toward renewable energy sources. However, the implementation of multiport converters, like the 3-port converter, has posed challenges related to increased current flow in certain devices, resulting in higher system losses. Basu’s research addresses this critical issue by developing a comprehensive power loss model that accounts for both conduction and switching losses. This model forms the basis of the algorithm’s objective function, allowing for a targeted reduction in energy waste.
“The integration of our loss minimization algorithm can lead to significant operational savings in microgrid systems,” Basu remarked. “By optimizing the performance of the 3-port converter, we can improve the overall efficiency of energy distribution, which is crucial for the commercial viability of microgrids.”
The algorithm employs the optimization function “fmincon,” utilizing a trust region method based on the interior point technique. This sophisticated approach not only minimizes losses but also enhances computational efficiency through a graphical analysis that predefines solutions for various scenarios. By adjusting port current angles, the algorithm seamlessly integrates its optimization results into the microgrid control structure, ensuring that the converter operates at peak efficiency.
The practical implications of this research are significant. Through Controller Hardware-in-the-Loop (C-HIL) experimentation, Basu and his team demonstrated an impressive average reduction of 32 to 46% in losses, depending on power flow conditions. This level of efficiency not only improves the sustainability of microgrids but also enhances their economic feasibility, making them more attractive for commercial applications. “Our findings show that real-time applications can benefit immensely from this algorithm, paving the way for smarter, more efficient energy systems,” Basu added.
As the energy sector continues to innovate, Basu’s research could shape the future of energy distribution and consumption. With microgrids poised to play a crucial role in the transition to renewable energy, the ability to minimize losses and optimize performance will be essential. This work not only reinforces the importance of advanced algorithms in energy management but also highlights the potential for commercial adoption of such technologies in the broader market.
