“…Network modelling is fundamental for simulating the response of district heating system to changes in operating conditions [7,12]. Although the modelling of temperature distribution in thermal networks has been studied for a long time, there are still gaps in understanding the needs of newer and current generations of networks.…”

“…Stevanovic [18], among others. However, the fluid dynamic problem of DH pipelines is non-linear and this is usually solved by numerical methods which are often computationally expensive [7]. Thereafter, in order to reduce the efforts of dynamic simulations and as an effect of the reduction of the network's temperature, steady state simulations and simplifications of the network structure are used to simulate the network at considerably reasonable levels of accuracy [19].…”

“…District heating (DH) systems are widely used to meet heating demand [7] and allow a more efficient operation of multiple RE heating systems, and are therefore a tool for fostering the acceleration of the decarbonisation in the heating sector [8]. Also, they are particularly beneficial for decarbonisation as a significant share of the heat demand can be met by replacing only a few heat generation plants with RE as a source.…”

<p>Fourth and fifth generation district heating (DH) systems have emerged as major contributors to decarbonise the heat sector. However, questions arise about the future trajectory of their existing older versions, which operate at relatively high temperatures. The transformation pathways and operation of DH networks require accurate but simple models to enable rapid simulation. This paper proposes a method for modelling a steady-state DH network using an open-source tool (TESPy) that numerically solves the system of equations and provides a high degree of flexibility in topology and parameterisation. Furthermore, a calibration method using 12 hours of measured data is proposed, which considers the aggregated heat conduction as the calibration parameter and solves the optimisation problem by reducing the difference between the simulated and measured temperature. A DH system in southern Germany with a 15 minute time resolution dataset for the months of January to March 2022 was used as a case study to validate both methods. For the uncalibrated model, the mean absolute error of feed temperatures at all consumers varies from 0.03 °C to 2.34 °C. After calibration, TESPy was found to obtain a mean absolute temperature error of 0.02 °C to 0.5 ◦°C, excluding the cases with high data uncertainty. The accuracy of the simulated temperature enhanced significantly after calibration, thus validating the proposed model. Additionally, it was also observed that the simulated system is more accurate at rather high mass flow conditions. </p>

“…Las organizaciones en la actualidad muestran gran sensibilidad en cuanto a sus procesos de gestión y administración por los cambios tecnológicos y formas diferentes de proceder por los entes participantes dentro de ellos. (Brown et al, 2022) los procesos educativos no se escapan de esta sensibilidad, por lo contrario, está sujeto a innovaciones tecnológicas de enseñanza y aprendizaje a consecuencia del avance vertiginoso de la tecnología. La práctica con ello, se hace cada vez se hace imprescindible; durante el aprendizaje, el estudiante con la interacción de simuladores, programas, calculadoras, maquetas, entre otros.…”

“…This phenomenon started with the uncontrolled urban expansion and overpopulation of the last mid-century, which has led to the phenomenon of anthropogenic climate change. [3,4]. As a result, higher record-breaking daily temperatures have been recorded through the last years [5], with a detectable increase in local metropolitan ambient temperatures compared to the rural surroundings: the acknowledged ''Urban Heat Island'' (UHI) effect [6,7].…”
