摘要

先进绝热压缩空气储能 (advanced adiabatic compressed air energy storage

AA‑CAES) 系统是提升电热联合 (combined heat and power

CHP) 系统运行灵活性的有效手段。但目前的研究大多针对其储放电能力的提升，忽略了其对热功率的双向调节能力，导致其综合利用效率较低。因此提出考虑 AA‑CAES 系统电热灵活性的电热联合系统实时调度策略。在风电高峰时，AA‑CAES 系统压缩空气储电，同时释放压缩热储存在储热罐中，其中富余压缩热可以供给热用户。在风电低谷时，AA‑CAES 系统吸收系统富余热，与储热罐一同供给膨胀机膨胀空气发电。同时，考虑热能的传输延时特性，建立了考虑 AA‑CAES 系统热响应延迟的电热联合系统实时调度模型，改进传统的电热功率平衡。算例结果表明，通过发挥 AA‑CAES 系统在电能与热能方面的双向调节能力，促进了电热联合系统的热电解耦，从而显著提高了系统的运行灵活性和对风电的消纳能力。

Abstract

Advanced adiabatic compressed air energy storage (AA‑CAES) systems are an effective means of enhancing the operational flexibility of integrated electricity‑heat systems. However

current research mainly focuses on improving their electricity storage and discharge capabilities while overlooking their bidirectional heat power regulation capability

resulting in relatively low overall energy utilization efficiency. Therefore

a real‑time dispatch strategy for integrated electricity‑heat systems considering the electricity‑heat flexibility of AA‑CAES systems is proposed. During the peak of wind power

AA‑CAES systems compress air for electricity storage while releasing compression heat to be stored in the thermal storage tank

with surplus compression heat supplied to heat loads. During periods of low wind power output

the AA‑CAES system absorbs surplus heat from the system and

together with the thermal storage tank

supplies heat to the expansion process for electricity generation. Furthermore

considering thermal energy transmission delays

a real‑time dispatch model of the integrated electricity‑heat system incorporating the thermal response delay of the AA‑CAES system is established

thereby improving the traditional electricity‑heat power balance. Case studies demonstrate that exploiting the bidirectional regulation capabilities of AA‑CAES systems in both electricity and heat enables greater decoupling between electricity and heat

thereby significantly enhancing the operational flexibility of the integrated system and its wind power accommodation capability.
