In order to improve the ability of integrated energy system to absorb new energy and reduce system operating cost. This paper takes the integrated energy system of industrial park as the research object, and proposes an optimal scheduling model considering the integrated demand response. Firstly, the basic model of the park integrated energy system including CHP unit, gas boiler, electric boiler and other coupled equipment was established, and the flexible loads on the demand side of the system are divided into three types: transferable loads, interruptible loads, and replaceable loads. Among them, replaceable loads have realized the coordination and interaction between multiple types of energy. Secondly, the schedulable value of electric vehicles is discussed, combined with the time-of-use electricity price and load curves of the system, the charging and discharging of electric vehicles are orderly guided to participate in the optimal scheduling of integrated energy system. Finally, an example analysis was carried out to verify the advantages of the proposed model in terms of operating cost, consumption of new energy and peak loads shaving .
