In order to further improve the energy consumption potential and system energy utilization effi ciency on the demand side of regional integrated energy system (RIES), taking into account economy and energy effi ciency, a RIES optimal operation model and strategy considering integrated demand response (IDR) and exergy effi ciency are proposed. Firstly, the IDR is modeled, the exergy effi ciency of RIES is analyzed, and an exergy effi ciency model considering IDR is established. Secondly the RIES multi-objective optimization model is established with the goal of the lowest economic cost and the highest exergy effi ciency. In order to obtain a series of Pareto frontier solutions with uniform distribution, the normal boundary intersection is used to solve the multi-objective. Finally, the system economic cost and exergy effi ciency under four diff erent scenarios are analyzed. A practical example is used to verify the proposed model. The results show that considering the comprehensive demand response in RIES can eff ectively reduce the system cost. Through multi-objective analysis, it is verifi ed that the reasonable addition of comprehensive demand response can further improve the system exergy effi ciency and stimulate the exergy consumption potential on the demand side.
