Recent research published in the Iranian Journal of Electrical and Electronic Engineering has introduced an innovative approach to managing hybrid AC/DC microgrids, which are becoming increasingly vital as the world pivots toward renewable energy sources. The study, led by Mitesh Kumar from NIT Kurukshetra, explores the implementation of a bidirectional interlinking converter (BIC) that enhances power flow control between AC and DC subgrids, particularly in islanded modes where the microgrid operates independently of the main grid.
Hybrid microgrids combine various distributed generation sources, such as solar panels, wind turbines, and energy storage systems (ESS), allowing for more efficient and reliable energy management. The research highlights the importance of effective voltage and frequency regulation, especially given the intermittent nature of renewable energy sources. By modifying conventional droop control strategies, the proposed system improves power sharing and ensures that voltage and frequency remain stable even under varying generation and load conditions.
Kumar’s team conducted simulations using real-time data on solar irradiance and wind speed from the National Renewable Energy Laboratory, demonstrating the system’s robustness across different generation and load scenarios. The results showed significant improvements in both transient and steady-state conditions, with frequency and voltage variations remaining within acceptable limits. “In the transient state, the overshoot and settling time of frequency and voltage are improved,” Kumar noted, emphasizing the system’s ability to handle fluctuations effectively.
The implications of this research are significant for various sectors, particularly in energy management and smart grid technologies. As more businesses and communities seek to integrate renewable energy sources, the ability to manage hybrid microgrids efficiently will become crucial. This technology not only enhances energy reliability but also opens up new business opportunities in energy storage, grid management, and the development of smart energy solutions.
As industries look to reduce their carbon footprint and transition to cleaner energy sources, the insights from this study could pave the way for more resilient and adaptable energy systems. The commercial potential is vast, particularly for companies involved in renewable energy generation, energy storage solutions, and smart grid technologies, which could leverage these findings to enhance their offerings and improve operational efficiency.
