In a significant stride towards optimizing energy utilization, researchers from Shenyang University of Technology have unveiled an analytical method aimed at enhancing the efficiency of power grid dispatching through centralized thermal storage. This innovative approach is particularly crucial for regions with abundant wind energy but facing challenges in harnessing it effectively, often leading to high rates of abandoned wind power.
The lead author, CHU Shuai, and his team have focused on the northern region of China, where large-capacity heat storage devices, primarily funded by thermal power plants, have been implemented to bolster adjustment flexibility within the grid. “By improving the timing of when these heat storage devices are activated, we can significantly reduce the amount of wind energy that goes unused,” CHU stated. This research not only highlights the intricate relationship between the operational timing of heat storage and the occurrence of abandoned wind power but also delves into the complexities of deep peak shaving—an essential process for managing energy demand and supply effectively.
The findings suggest that strategic input timing of thermal storage can mitigate the abandonment of wind energy, thereby enhancing overall grid efficiency. The research proposes a novel calculation method for assessing both the power consumption of these heat storage devices and the rates of abandoned wind power. This dual focus is poised to transform how energy providers manage resources, ensuring that more renewable energy is utilized rather than wasted.
The implications of such advancements are profound for the energy sector. As countries strive for cleaner energy solutions, optimizing the integration of renewable resources like wind power becomes paramount. By reducing the abandoned wind rate, energy companies can not only improve their operational efficiency but also contribute to the broader goals of sustainability and carbon reduction.
“This research underscores the potential for thermal storage systems to act as a buffer, allowing us to store excess wind energy for later use,” CHU explained. “The commercial benefits are clear: less wasted energy translates into lower costs and a more reliable energy supply.”
As the energy landscape continues to evolve, the insights from this study, published in ‘发电技术’ (which translates to ‘Power Generation Technology’), could pave the way for innovative practices in energy management. For those in the industry, the research emphasizes the importance of adaptive strategies that align with renewable energy goals, ultimately shaping the future of energy consumption and sustainability.
