A recent study led by S. Chitra Selvi from the Department of Electrical and Electronics Engineering at the University College of Engineering, Dindigul, has introduced a new approach to enhancing energy efficiency in microgrids through an innovative power conversion system. Published in the IEEE Journal of the Electron Devices Society, the research focuses on the integration of solar photovoltaic (PV) energy sources with microgrid architectures using a Quadratic Boost Converter (QBC) controlled by a Sliding Mode Controller (SMC).
Microgrids are localized networks that can operate independently or in conjunction with the main power grid. They often incorporate renewable energy sources like solar and wind, as well as fuel cells, to provide sustainable energy solutions. However, the challenge lies in efficiently managing the varying power outputs from these renewable sources and ensuring stable voltage levels for connected loads. This is where the QBC comes into play. As a high voltage gain DC to DC converter, it helps maximize energy extraction from solar PV systems while maintaining the necessary voltage levels for effective operation within the microgrid.
Selvi’s research delves into how the SMC can optimize the performance of the QBC, particularly in maximizing energy harvest from solar panels. “The applicability of the Sliding Mode Controller for the maximized harvest of energy from a solar photovoltaic system using the QBC is studied,” Selvi states, highlighting the potential of this technology in improving energy yield from solar installations.
The implications of this research are significant for the energy sector. As the demand for renewable energy increases, so does the need for efficient systems that can manage energy flow and storage effectively. The integration of the QBC with SMC not only enhances energy efficiency but also contributes to the stability of microgrids, making it a viable solution for both urban and rural energy applications. This technology could lead to reduced energy costs and improved reliability in power supply, which is particularly crucial in areas prone to outages or where grid access is limited.
Moreover, the findings from this study present commercial opportunities for companies involved in renewable energy technologies and power electronics. The ability to implement high-efficiency converters in microgrid systems can attract investments, foster innovation, and ultimately accelerate the transition to sustainable energy solutions.
