Abstract

In order to further improve the energy consumption potential and system energy utilization efficiency on the demand side of regional integrated energy system (RIES), taking into account economy and energy efficiency, a RIES optimal operation model and strategy considering integrated demand response (IDR) and exergy efficiency are proposed. Firstly, the IDR is modeled, the exergy efficiency of RIES is analyzed, and an exergy efficiency 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 efficiency. 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 efficiency under four different 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 effectively reduce the system cost. Through multi-objective analysis, it is verified that the reasonable addition of comprehensive demand response can further improve the system exergy efficiency and stimulate the exergy consumption potential on the demand side.
