The development of sustainable and innovative solutions for the production and supply of
energy at district level is nowadays one of the main technical challenges. In the past, district …

The network optimization is vital for rational expansion of existing large-scale district heating
systems (DHSs), which typically involves hundreds or even thousands of design variables …

Abstract District Heating Network (DHN) pipes can be affected by faults that endanger
system reliability. Thus, this paper develops a novel modeling and diagnostic approach for …

Thermal energy storage (TES) is a key technology for enabling increased utilization of
industrial waste heat in district heating. The ability of TES to equalize offsets in demand and …

The goal of this paper was to evaluate heat loss and the demand of district heating (DH) in
the context of the fourth generation DH concept using a data-driven approach. The heat loss …

The main objective of this study is to investigate variations and peak values of actual heat
demand profiles in a centralized district heating (DH) network. Operational heat data is …

The empirical Colebrook equation from 1939 is still accepted as an informal standard way to
calculate the friction factor of turbulent flows (4000< Re< 108) through pipes with roughness …

As the coupling and integration of multi-energy flow in the integrated energy system (IES)
deepen increasingly, the cascading failure will develop across different energy systems …

ABSTRACT A district heating (DH) system in the Russian city of Omsk has been considered
as a case study. This study is based on the data set of temperature and demand recorded …

Efficient numerical simulation of thermo-hydraulic coupled conditions is critical for analysis
and control of DH network. However, for most of meshed DH network, the flow directions of …
