摘要：

针对先进绝热压缩空气储能系统中膨胀阶段需额外补充热源的问题,提出了一种采用槽式太阳能辅热的压缩空气储能冷电联产(CCSA)系统。采用槽式太阳能产生的中温热能提升压缩空气储能系统空气透平入口温度,达到提高储能容量和节省高温导热油的效果,并采用剩余高温导热油驱动[mmim]DMP/CH₃OH压缩吸收式制冷系统。CCSA系统动态数学模型通过耦合系统各子部件能质守恒定律建立。在设计工况下对CCSA系统释能阶段进行了运行工况预测,并开展了系统的能量分析和㶲分析。研究了月份、纬度、高压发生器温度、制冷系统辅助压缩机压比对CCSA系统热力性能的影响。将CCSA系统的太阳能有效利用率与常规太阳能驱动氨动力系统进行了对比,将CCSA系统的能量效率和㶲效率与先进绝热压缩空气储能系统和太阳能辅助再热压缩空气储能系统进行了对比。结果表明:CCSA系统的太阳能有效利用率较太阳能氨动力系统能提升8.44%至13.87%;CCSA系统的能量效率和㶲效率均高于对比系统。

Abstract:

To overcome the issue of requiring additional heat sources during the expansion stage of advanced adiabatic compressed air energy storage (AA-CAES) systems, a combined cooling and power system with compressed air energy storage and auxiliary heating via parabolic trough solar collectors is proposed. The turbine inlet temperature of the CAES system is increased using the solar trough energy, thereby increasing its storage capacity and reducing the consumption of high-temperature heat transfer oil. The heat transfer oil saved via the first coupled parabolic trough solar system is used to drive the [mmim]DMP/CH₃OH compression-absorption refrigeration system. A dynamic mathematical model of the Combined Cooling with Solar Auxiliary (CCSA) system was established based on the conservation laws of mass and energy of each subsystem. The operating conditions of the CCSA system during the energy release phase under design conditions were simulated, and energy and exergy analyses were conducted. The impacts of months, latitude, high-pressure generator temperature, and auxiliary compressor pressure ratio of the refrigeration system on the thermodynamic performance of the CCSA system were investigated. The effective solar utilization efficiency of the CCSA system was compared with that of a conventional solar-driven ammonia power system. Moreover, its energy and exergy efficiencies were compared with those of the AA-CAES and Solar Auxiliary Reheating Compressed Air Energy Storage (SAR-CAES) systems. The results revealed that the effective solar utilization efficiency of the CCSA system was 8.44% to 13.87% higher than that of the solar-driven ammonia power system and its energy and exergy efficiencies were higher than those of the AA-CAES and SAR-CAES systems.
