Research on steam pipe storage effect of integrated electricity and heat energy systems for industry

Abstract

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.
