Abstract： Under the national dual-carbon policyand energytransition，the need forcoordinated development between compressed air energystorage（CAES）technologyand renewableenergy has grown significantly.A solarauxiary reheatingcompressed air energy storage（SAR-CAES）system is proposed.The system integrates a parabolic trough solar collectr withanadvanced adiabatic CAES system for achieving energy release.Amathematical model of the trough solar collectr and athree-stage expansionadvanced adiabaticcompressed air energy storage system were established.Using thediscretizationalgorithminMatlab，the models werecoupledtoanalyze theimpactofmonthsandlatitudesonkeysystem parameters.Results show that theresultant dynamic model satisfies thefirst and second laws of thermodynamics.After auxiary heating，theheat loadof theauxiliary heat exchanger increased clearly.Mediumregenerator andLowregenerator barely participated in heat exchange，but generated considerable exergic lossTheeficiencyof compressed air energy storageclearly improved after auxiary heating，reaching itspeak during thesummer solsticeat theTropicof Cancer.The efectiveutizationeficiencyofthesolarenergyinthissystemishigherthanthatofasolar-drivenammonia-water regenerative Rankine cycle system，with a maximum efficiency during the winter solstice一 67.86% higher than that of the ammonia-water power cycle.
