ABSTRACT=As an important direction for the development of energy system, the integrated energy system of a park plays an important role in the field of energy optimization and sustainable economic operation. In this paper, a low-carbon optimal operation model of the integrated energy system of an industrial park is proposed, considering a controllable flexible load response. First, the typical structure of the integrated energy system of the park and the model of each subsystem are introduced. Then, under the premise that flexible electrical and thermal loads can be used for adjustment energy utilization, a complete dispatch scheme is constructed according to the energy consumption characteristics and system operation characteristics of the integrated energy system. Finally, an optimal scheduling model for the combined supply and demand of the integrated energy system is established with the aim of minimizing the total operating cost. The YALMIP toolbox and the Cplex solver are used to verify the results of study. Simulation results show that the optimal scheduling of controllable loads can effectively reduce the comprehensive operating cost of community IES.
