Distributed Storage Modeling in District Heating Networks District heating networks are an essential component of a low-carbon ecosystem for energy in the residential sector. In particular, they enable efficient heat supply in urban areas, with very low CO2 emissions. In order to improve the efficiency of these networks and to be able to integrate low carbon production assets (heat pumps, solar thermal...), an effort has to be made for lowering the network operation temperature levels. This kind of transformation requires often intervention on the network design in order to upgrade part of the existing installation (pipes, substations, pumps). The integration of thermal storage solutions, strategically located on the distribution network and adequately piloted, is particularly promising.
