In order to investigate the thermal inertia of steam systems and address the scheduling challenges of low-carbon energy systems in industrial parks, a dynamic analysis model reflecting the spatiotemporal transmission of steam is proposed. A virtual steam pipe energy storage model is established, incorporating 5 key storage parameters and 3 indicators to quantify thermal inertia. The thermal inertia of a 163-node urban-scale steam system during operation is quantified, revealing a net stored heat of 7,440.3 kilograms and a discharge capacity of 10.16 tons within a 0.5-hour scheduling cycle, and an average discharge utilization rate of 14.59%. This paper provides quantitative basis for the analysis and optimization of steam systems in industrial parks.
