In a groundbreaking study published in ‘电力工程技术’ (Electric Power Engineering Technology), researchers from Southeast University have unveiled a novel approach to managing the increasing pressures of peak power demand within coastal power grids that heavily rely on nuclear energy. The lead author, WU Xi, and his team have developed a sophisticated optimized dispatch model that integrates various energy sources, including nuclear, photovoltaic, electrochemical storage, pumped storage, and thermal power. This innovative model aims to enhance the flexibility of nuclear power in responding to peak demand, a critical step in the transition to a low-carbon economy.
The study addresses a significant challenge: as renewable energy sources like solar and wind power become more prevalent, the need for reliable peak regulation intensifies. WU Xi emphasized the urgency of this issue, stating, “With the increasing share of new energy sources, our power systems face unprecedented challenges in maintaining stability and efficiency. Our research presents a solution that not only optimizes energy dispatch but also supports a greener future.”
At the core of the model is the introduction of 0-1 variables that precisely linearize the flexible output of nuclear power, allowing it to adapt more effectively to fluctuating demand. This flexibility is crucial, as traditional thermal power units often struggle with the frequent start-stop cycles required to balance the grid. By leveraging the reliable output of nuclear power, the proposed model significantly reduces the operational strain on these thermal units, leading to greater efficiency and lower emissions.
Moreover, the study introduces carbon trading mechanisms that align with the economic optimization goals of the system. By integrating these mechanisms, the model not only enhances the consumption of renewable energy but also positions nuclear power as a pivotal player in the low-carbon transition. “This approach not only addresses the immediate operational challenges but also sets the stage for a sustainable energy future,” WU Xi explained.
The implications of this research extend beyond theoretical advancements; they hold substantial commercial potential for the energy sector. As utilities worldwide grapple with the dual challenge of meeting demand and reducing carbon emissions, the findings from Southeast University could inform strategies that enhance grid reliability while promoting the use of cleaner energy sources.
The study’s successful simulations validate the model’s effectiveness, showcasing its ability to alleviate peak pressure on the system while optimizing overall operations. This breakthrough could inspire further developments in energy dispatch strategies, particularly in regions where nuclear power plays a significant role.
As the energy landscape continues to evolve, research like this underscores the importance of innovative solutions that blend traditional and renewable energy sources. The potential for economic and environmental benefits makes this study a pivotal contribution to the discourse on sustainable energy practices.
