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 ... -
Economic optimization for heat-prosumer- based district heating systems in unidirectional heating markets
Li, Haoran (Doctoral theses at NTNU;2022:18, Doctoral thesis, 2022) -
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 ... -
IEA EBC annex 53: Total energy use in buildings - Analysis and evaluation methods
Yoshino, Hiroshi; Hong, Tianzhen; Nord, Natasa (Journal article; Peer reviewed, 2017)One of the most significant barriers to achieving deep building energy efficiency is a lack of knowledge about the factors determining energy use. In fact, there is often a significant discrepancy between designed and real ... -
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 ...
