To face the climate change and global warming issues, European countries have set new targets in order to reduce the CO2 emissions to 40% by 2030 and to 80% by 2050.

Abstract

To face the climate change and global warming issues, European countries have set new targets in order to reduce the CO2 emissions to 40% by 2030 and to 80% by 2050. The district heating networks, and in particular low-temperature networks, due to their efficient heat supply and distribution represent a key point for meeting these goals, as well as the renewable sources integration. Nowadays, in fact, about 40% of the energy consumed in Europe is for heating, most of which is provided by fossil fuels employment. This article concerns the smart district heating, namely, the possibility of a bidirectional energy exchange between the district heating network and the connected users. The main purpose of this study is to evaluate the possibility of including a prosumer-that is, a customer who can both consume and produce heat-in an existing small/medium district heating network. To this purpose, an in-house-developed software has been applied to analyze whether and which user of the district heating network is more suitable to be set as prosumer and the effect of the installed distributed generation system on the network. The results show how the choice of a prosumer over another and how the amount of exchanged thermal power affect the performance of the network, with a consequent need of a modification in its operation and management.
