Abstract：Inorder tofurther improve theenergyutilizationeffciency，lowcarbonanduser demandresponse of the integratedenergysystem(IES),anIESoptimalschedulingmodeloftheintegratedenergysystemtakingintoaccountthestepped carbontradingmechanismandcoupleddemandresponseisestablished.Thearchitectureof theelectricity-gas-heat-coling IESis constructedtoimprovetheenergyutilizationeficiency.The steppedcarbontrading mechanismisintroduced intothesystem,nd thecouplingcharacteristicsoftheloadsonbothsupplyanddemandsidesareanalyzedbycombiningtheimpactsof time-of-day energy priceandnewenergyoutput,soastoobtain theloadsofelectricity，gas,heat,andcoldafterthecouplingofthedemand response.Withthegoalof minimizingthetotalsystemcost,theIESoptimalscheduling modelthat takesintoacountthestepped carbon trading mechanismandcouplingof demand responseisconstructed basedonconstraintconditions.This modelcan not onlyenhance thesystem'semisionreductioncapabilitybutalsoefectivelypromotecomprehensiveresponseof thesystem's electricity，gasheat,andcolingloads.Themulti-scenarioexampleiscariedoutforvalidation.Theresultsshowthatthismodel caneffectivelyreducecarbonemissonsbyabout18%,improvethedemandresponseofusersbyabout2O%,andreducethe total system operation cost by about 3%
