摘要

可再生能源发电技术的广泛应用对电网的稳定性提出了严峻的挑战。开发先进的储能技术至关重要。卡诺电池具有造价低、安装灵活等优点。然而，传统卡诺电池的低往返效率限制了它的广泛应用。本研究构建了增强型卡诺电池以实现高效储能，并讨论了各种增强技术的性能。以中国三个城市为应用地点，选择工业低品位余热回收作为应用场景，分析了增强型卡诺电池的可行性。结果表明，热泵模块采用注汽技术，有机朗肯循环模块采用双压蒸发技术，整体性能最优。与传统卡诺电池相比，改进型卡诺电池的投资回收期可缩短76.8%，平准化储能成本可降低26.7%。

Enhanced Carnot battery for high-efficiency energy storage: Feasibility analysis

The widespread application of renewable energy generation technologies poses a serious challenge to grid stability. It is essential to develop advanced energy storage technologies. The Carnot battery has advantages such as low construction cost and high installation flexibility. However, the low round-trip efficiency of conventional Carnot battery limits its widespread application. In this study, the enhanced Carnot battery is constructed to achieve high-efficiency energy storage, and the performance of various enhanced technologies is discussed. Taking three cities in China as the application sites, the feasibility of the enhanced Carnot battery is analyzed by selecting industrial low-grade waste heat recovery as the application scenario. The results show that the overall performance is optimal when the heat pump module applies the vapor injection technology, and the organic Rankine cycle module applies the dual-pressure evaporation technology. Compared with conventional Carnot battery, the payback period of the enhanced Carnot battery can be shortened by 76.8%, and the levelized cost of storage can be reduced by 26.7%.
