Abstract: For industrial parks, there are various types of energy sources and multi-energy complementarity characteristic. The energy storage characteristics of buildings on the user-side in industrial parks can provide additional operational flexibility and help respond to real-time electricity prices with a certain adjustment capability. This paper proposes a day-ahead scheduling model for an integrated energy system in an industrial park that considers the energy storage characteristics of the cooling areas. Firstly, the component modeling in the industrial park is carried out, and the energy storage model of the cooling areas based on detailed thermal model of buildings is further established. Then, with the objective function of minimizing the total operating cost of the integrated energy system in industrial park, the components and energy storage models are integrated into the scheduling model, and the scheduling framework is analyzed for optimal management. Finally, the validity of the model is verified by numerical simulation. The results show that the energy storage characteristics of the cooling areas can effectively reduce the purchased power and operating cost.

Key words: industrial park, integrated energy system, energy storage characteristics, day-ahead optimal scheduling
