In a groundbreaking study published in ‘Shanghai Jiaotong Daxue xuebao’ (Journal of Shanghai Jiao Tong University), researchers from the Faculty of Information Engineering and Automation at Kunming University of Science and Technology have unveiled a robust optimal scheduling model for agricultural microgrids that integrates irrigation systems under uncertain conditions. This innovative approach is set to transform energy supply in rural areas, particularly where renewable energy resources are abundant yet unpredictable.
The research, led by YANG Sen, GUO Ning, and ZHANG Shouming, addresses a critical challenge faced by agricultural microgrids: the fluctuating nature of renewable energy output and varying electricity load demands. By incorporating a pumped hydro storage (PHS) power station into the microgrid system, the team has developed a model that not only minimizes operational costs but also enhances the absorption of renewable energy. “Our model takes into account the diverse and multi-constraint nature of agricultural operations, ensuring that both power and water load demands are met efficiently,” YANG stated in an interview.
The implications of this research are substantial for the energy sector. The integration of microgrids with irrigation systems could lead to significant cost savings for farmers and agricultural businesses, enabling them to harness local water resources and renewable energy more effectively. This is particularly relevant in the context of increasing global energy demands and the need for sustainable practices in agriculture. The gravitational whale optimization algorithm (GWOA) developed in this study stands out for its ability to deliver competitive solutions compared to traditional methods, such as the widely used CPLEX solver.
Moreover, the study highlights the impact of precipitation uncertainty on irrigation system operational costs, emphasizing the necessity of utilizing PHS power stations. This insight could lead to more resilient agricultural practices, allowing farmers to adapt to changing weather patterns and ensure consistent water supply for their crops.
As the world moves towards renewable energy and sustainable agricultural practices, this research could pave the way for future developments in energy management systems. By leveraging local resources and ensuring reliable energy supply, agricultural microgrids could become a cornerstone of rural energy strategies.
