DISTRICTLAB-H: A new tool to optimize the design and operation of district heating and cooling networks
Résumé
This article introduces a new scalable thermo-hydraulic modeling framework for dynamic simulation of small to large-scale District Heating (DH) and Cooling (DC) networks. The roots of this new development are to be found in the need for a more efficient solver including an accurate substation model. Following a comprehensive literature review, the solver is presented and validated using existing dynamic experimental data for a straight pipe. In a following step, a real large DH network, from the city of Metz (FR), is modeled and simulated, with results showing good consistency with field data. The numerical efficiency of the proposed approach is then assessed, leading to a quasi-linear scaling of the algorithm up to sizes comparable to the largest DH systems in Europe and to performances that compares very favorably to other models described in the literature. This work opens pathways towards the definition of advanced network architecture and the optimization of design and control strategies. To illustrate these new possibilities, the last section briefly presents real life use cases addressed with the tool such as the evaluation of an innovative 3-tubes architecture, the network resizing for lowering the temperature and the real time control optimization of the supply temperature.
