Abstract

With the expansion of renewable energies, district heating (DH) systems are becoming increasingly complex. Various heat sources like solar thermal plants and combined heat and power (CHP) plants are integrated in parallel, in addition thermal energy storages (TES) are often used to balance load and heat generation. Sophisticated software solutions are required to optimise the plant operation. Based on deterministic physical models and artificial neural networks, the software Heating Network Navigator (HN-Navi) is being developed to optimise the operation of such systems. Since tests in the real system are not possible for reasons of supply security, the HN-Navi is first tested in a software-in-the-loop (SiL) environment. TRNSYS (version 18) is used as simulation software to create a complex reference model (CRM) as basis for the SiL environment. The complexity of such real energy systems can lead to potentially high computing costs when it comes to simulating or optimising their operation as realistically and accurately as possible. For this reason, both software tools, i.e. HN-Navi and CRM, will be developed and tested with regard to the Brühl solar DH system in Chemnitz (Germany), whereby the finished software will also be used for other heat supply systems. TRNSYS offers the possibility to develop own models for all system components, with which a proper reproduction of the real system can be achieved. Within the scope of the project, practical tests and extensive quantitative software comparisons with the real system will also be carried out. The article reports on the development of this SiL environment and its practical feasibility.
