Digitalization of District Heating and Cooling Systems

District heating and cooling (DHC) networks are often run with a small number of sensors and actuators to provide the necessary supply and to maximize economics based on a predetermined high ecologic performance. With better knowledge of the demand and flexibility options, it is feasible to optimize heat generation and network functioning overall. Improved network management based on real-timemeasurement data and the incorporation of newdigital business processes is made possible by a greater deployment of information and communication technology. Clarifying the role of digitalization for various components within district heating and cooling systems is necessary for ongoing growth, as is promoting opportunities for the integration of digital processes into DHC systems. Digital technologies are expected to improve the efficiency and system integration of additional renewable sources while also making the entire energy system smarter, more reliable, and more efficient. Future district energy systems could be able to completely optimize their plant and network functioning while empowering the end user thanks to digital applications. However, there are still more difficulties to be overcome, including issues with data privacy and security as well as issues with data ownership. The research findings from the IEA DHC Annex TS4 on "Digitalization of District Heating Systems - Optimized Operation and Maintenance of District Heating and Cooling Systems via Digital Process Management" are presented and discussed in this publication. https://www.iea-dhc.org/the-research/annexes/2018-2024-annex-ts4.
