槽式太阳能耦合压缩空气储能系统动态特性研究
Dynamic characteristics of a trough solar energy-coupled compressed air energy storage system
摘要
Abstract
Under the national dual-carbon policy and energy transition,the need for coordinated development between compressed air energy storage(CAES)technology and renewable energy has grown significantly.A solar auxiliary reheating compressed air energy storage(SAR-CAES)system is proposed.The system integrates a parabolic trough solar collector with an advanced adiabatic CAES system for achieving energy release.A mathematical model of the trough solar collector and a three-stage expansion advanced adiabatic compressed air energy storage system were established.Using the discretization algorithm in Matlab,the models were coupled to analyze the impact of months and latitudes on key system parameters.Results show that the resultant dynamic model satisfies the first and second laws of thermodynamics.After auxiliary heating,the heat load of the auxiliary heat exchanger increased clearly.Medium regenerator and Low regenerator barely participated in heat exchange,but generated considerable exergic loss.The efficiency of compressed air energy storage clearly improved after auxiliary heating,reaching its peak during the summer solstice at the Tropic of Cancer.The effective utilization efficiency of the solar energy in this system is higher than that of a solar-driven ammonia-water regenerative Rankine cycle system,with a maximum efficiency during the winter solstice-67.86％higher than that of the ammonia-water power cycle.关键词
