In order to fully explore the ability of various types of integrated demand response (IDR) to participate in the coordination of integrated energy system (IES) optimal operation, this paper firstly analyzes the multi-time scale characteristics of IDR, establishes various types of IDR models and formulates multi-time scale response strategy of IDR. Then, on the basis of the strategy, a multi-time scale optimization operation model of IES aimed at economic optimization is established. The model is divided into three stages: day-ahead, intra-day upper and intra-day lower stages. In the day-ahead stage, an economically optimal day-ahead scheduling plan is formulated. In the intra-day stage, the output of cooling/heat, electricity/gas related equipment is managed in different layers by dividing the long and short time scales. Finally, the analysis of a calculation example shows that the proposed model can effectively reduce the operating cost and give full play to the potential of equipment with different response capacities to participate in intra-day operation.

Key words: integrated energy system, integrated demand response, multi-time scale, optimal operation
