Modélisation et optimisation d’un système multi-énergies pour le chauffage urbain

The building sector is one of the most energy-intensive, consuming up to 45

District heating systems (DHS) represent an advantageous centralized solution for reducing both energy consumption and GHG emissions. Since their appearance in the 19th century, these systems have progressively established in many cities around the world as key infrastructures, offering a collective and efficient approach to satisfying the thermal needs of dense urban areas.

The integration of renewable energies in DHS is part of a sustainable approach, with the main aim being to reduce energy consumption from fossil sources and promote the use of renewable heat/cooling. However, due to the intermittent nature of these renewable sources, the use of thermal energy storage systems is an essential component in ensuring efficient operation of these DHS.

This work proposes an innovative approach that combines renewable heat production with optimal distribution and thermal storage based on a stratified tank.

The focus is on the development of a dynamic modeling tool for a green heat system for collective heating/ cooling of buildings, to ensure renewable heat production, modeling and dynamic simulation of heat losses and loads in the system, as well as sensible storage, ensuring an efficient response to the needs of end-users. This numerical tool will be capable of dimensioning and predicting the dynamic operation of DHS under different operating conditions.
