In a significant stride towards greener and more adaptable energy systems, researchers from Shanghai University of Electric Power have developed a novel two-stage optimal dispatch strategy for integrated energy systems (IES) that incorporates oxy-fuel combustion technology. This breakthrough, published in the *Journal of Shanghai Jiaotong University*, promises to enhance the flexibility and economic performance of energy systems while curbing carbon emissions.
The study, led by PENG Chuxuan and colleagues, focuses on oxy-fuel combustion, a promising carbon capture technology for coal-fired power plants. By integrating this technology with optimal operation strategies for IES, the researchers aim to address the dual challenges of energy flexibility and carbon reduction.
“Our proposed strategy not only improves the flexibility of the integrated energy system but also enhances its economic performance,” said PENG Chuxuan, lead author of the study. “This is a crucial step towards achieving a more sustainable and efficient energy future.”
The researchers first established a model of an integrated energy system with oxy-fuel combustion units (Oxy-IES). They then developed a matrix model of multi-energy flexibility constraints for Oxy-IES to better understand the supply and demand relationship of flexibility within the system. The two-stage optimization dispatch strategy involves optimizing the output of each unit to minimize daily operating costs, including carbon trading, in the day-ahead stage. In the intraday stage, the rapid variable load capacity of the oxy-fuel combustion unit improves the system’s flexibility.
The simulation results of Oxy-IES demonstrated that the proposed strategy can indeed improve the flexibility and economy performance of the IES while reducing carbon emissions. This research has significant implications for the energy sector, particularly for coal-fired power plants looking to adopt more sustainable and flexible operations.
“As the energy sector continues to evolve, the integration of advanced technologies like oxy-fuel combustion with optimal dispatch strategies will be key to achieving a low-carbon future,” said PENG Chuxuan. “Our work provides a solid foundation for further research and practical applications in this area.”
The study, published in the *Journal of Shanghai Jiaotong University*, highlights the potential of oxy-fuel combustion technology in transforming the energy landscape. By enhancing the flexibility and economic performance of integrated energy systems, this research paves the way for more sustainable and efficient energy solutions. As the world grapples with the challenges of climate change and energy demand, such innovations offer hope for a greener and more resilient future.
