| 摘要: |
| 大规模清洁储能技术之一的先进绝热压缩空气储能(AA-CAES)具备热电联供、联储的能力，可作为能量枢纽接入综合能源系统，以提高系统运行的灵活性，促进新能源消纳。提出了一种可直观反映AA-CAES功率约束和储能状态约束的运行可行域刻画方法，为理解AA-CAES的热电耦合关系，分析热电联供模式的运行特点，评估系统的运行灵活性、供能能力和调节裕量提供了一种可视化工具。在此基础上，研究了运行可行域的形状和特点，分析了考虑供热比变化和计及宽工况影响的运行可行域处理方法，并探讨了运行可行域作为分析工具在实时调度中的应用。以某区域综合能源系统为例，验证了所提运行可行域分析方法的有效性和实用性。 |

| Abstract: |
| AA-CAES(Advanced Adiabatic Compressed Air Energy Storage),one of the large-scale clean energy storage technologies, has the thermal-electric co-generation and co-storage capacity, which can be used as an energy hub to connect to the integrated energy system, so as to improve the operation flexibility of system and promote the consumption of renewable energy. An operation feasible region characterization method is proposed, which can directly reflect the power constraint and energy storage state constraint of AA-CAES, providing a visual tool for understanding the thermoelectric coupling relationship of AA-CAES, analyzing the operation characteristics of thermal-electric co-generation mode, and evaluating the operation flexibility, energy supply ability and adjustable range of the system. On this basis, the shape and characteristics of operation feasible region are studied, the processing method of operation feasible region considering the variation of heating ratio and the influence of wide operating conditions are analyzed, and the application of operation feasible region as an analytical tool in the real-time dispatching is discussed. Taking a regional integrated energy system as an example, the validity and practicability of the proposed operation feasible region analysis method are verified. |
