Distinguish between the economic optimal and lowest distribution temperatures for heat-prosumer-based district heating systems with short-term thermal energy storage
Li, Haoran; Hou, Juan; Hong, Tianzhen; Nord, Natasa (Peer reviewed; Journal article, 2022)Decreasing distribution temperature is the key driving force for energy-efficient and economic-competitive district heating (DH) systems, powering the transition from the 1st generation high-temperature steam-based DH ... -
Energy, economic, and environmental analysis of integration of thermal energy storage into district heating systems using waste heat from data centres
Li, Haoran; Hou, Juan; Hong, Tianzhen; Ding, Yuemin; Nord, Natasa (Peer reviewed; Journal article, 2021)Data centres produce waste heat, which can be utilized in district heating systems. However, the mismatch between data centres’ heat supply and district heating systems’ heat demands limits its utilization. Further, high ... -
A fast and effective method for modelling and optimizing district heating systems in the Modelica language
Li, Haoran; Hou, Juan; Nord, Natasa (Chapter, 2022)A district heating system is a centralized energy system that supplies heat to end users such as buildings and industrial facilities. This centralized system may have multiple heat sources, a complex distribution network, ... -
Investigation of Model Predictive Control Application in District Heating Systems with Distributed Sources
Hou, Juan (Doctoral theses at NTNU;2022:273, Doctoral thesis, 2022)District heating (DH) systems, which can integrate various available heat sources, have proven to be an energy-efficient and environment-friendly way to satisfy buildings’ heating demands. However, with the transition from ... -
Model predictive control for a university heat prosumer with data centre waste heat and thermal energy storage

Optimal control of secondary side supply water temperature for substation in district heating systems
Hou, Juan; Li, Haoran; Nord, Natasa (Journal article; Peer reviewed, 2019)Low temperature is the most significant feature of the future district heating system- the 4th generation district heating (4GDH). However, a widely used control strategy for supply water temperature in substation is ... -
Optimize heat prosumers' economic performance under current heating price models by using water tank thermal energy storage
Li, Haoran; Hou, Juan; Tian, Zhiyong; Hong, Tianzhen; Nord, Natasa; Rohde, Daniel (Peer reviewed; Journal article, 2021)Due to heat prosumers' dual roles of heat producer and heat consumer, the future district heating (DH) systems will become more flexible and competitive. However, the current heating price models have not yet supported the ... -
Techno-economic analysis of implementing thermal storage for peak load shaving in a campus district heating system with waste heat from the data centre
Li, Haoran; Hou, Juan; Ding, Yuemin; Nord, Natasa (Peer reviewed; Journal article, 2021)Peak load has significant impacts on the economic and environmental performance of district heating systems. Future sustainable district heating systems will integrate thermal storages and renewables to shave their peak ...
