Abstract: Integrated energy system for park can realize the complementation and cascade utilization of dif-ferent energy sources in the park, improve the efficiency of utilizing energy, and reasonably inte-grate advantages of various subjects. On the other hand, with the development of smart grid, the potential for demand-side flexible resources to participate in regulation has been constantly ex-plored. This paper mainly studies the optimal operation regulation of integrated energy system for park when considering the integrated demand response. Firstly, the framework of IESP is con-structed, three economic entities including energy suppliers, operators and users are determined, and the method called Stackelberg game is given. Secondly, the flexible model for users is con-structed and the energy flow coupling equipment owned by operators is modeled. On this basis, the optimization and regulation strategy of park operation considering demand response is developed and the case is analyzed. The simulation results show that the park benefits more and promotes the consumption of renewable energy.
