Research on the influence of dynamic characteristics of heating networks on operation characteristics of integrated electricity and heating systems considering the refined heat network model

The integrated electricity and heating system(IEHS) consists of electricity, heating systems, and energy coupling equipment. The complex topology and heterogeneous energy flow transmission characteristics make it challenging to establish a universal model. This article conducts research on modeling and solving methods for IEHS. A steady-state hydraulic model considering pipelines, pumps, and adjustable valves was established and combined with a dynamic heating system model to form a quasi dynamic heating system model. Furthermore, a comprehensive energy system model for IEHS was constructed, and a general model solving method was established. Finally, the effectiveness of the method was validated in a case study of an IEHS.
