| Abstract |
Energy community and sectoral coupling of energy resources are considered a viable solution to achieve energy security and climate neutrality in the built environment. Studies have shown that a fifth-generation district heating and cooling network offers a platform for harvesting, and cross-sectoral integration of local thermal resources and electrical network. In this research, through a detailed digital twin of a community based on Malmö, Sweden, we analyzed, the effect of different building composition on the system performance and energy balance of low temperature district heating and cooling network. Six decentralized substations each equipped with heat pumps, and shallow geothermal borefield, all of which connected by a unidirectional two pipe network is the main characteristics of the studied community. The modeling and development of digital twin was carried out in Modelica using Dymola application interface. Different mixes of office buildings, residential apartments and shopping complexes were included in the model to replicate the real-life scenario of the community. Preliminary results show that a mix of substations with two office buildings, one residential building and a shopping complex enhances the seasonal performance factor of the overall network by 1.5 in comparison to the standalone operation of those substations. Moreover, the potential to reduce carbon emissions and pathways for integrating locally available energy resources into urban heating and cooling network is discussed. |
