Aiming at the problem that the traditional demand response cannot meet the applications of integrated energy system(IES)in the aspect of thermal system description,a joint optimalscheduling model foran IES of electricity,gas, and heatwith the power user-side participationis proposed. The classifiedtransferable power load is used to participate in the demand-side power adjustment;the coupling amongelectricity,gas,and heat inthe system,the time-of-useelectrici?ty price,gas price,etc.,are considered comprehensively,and the time-shift characteristi...
