abstract = {A promising way to make use of waste heat sources is to
distribute the heat to nearby buildings via district heating
systems to cover the heat demands of the buildings. The
integration of a waste heat source into an existing district
heating system must be studied in advance to avoid
difficulties in network operation and to ensure the required
heat supply to all connected buildings. Simultaneously,
supply temperature reduction can improve the overall system
efficiency and should also be considered for a sustainable
transformation of existing district heating systems.In this
paper, we develop a district heating model with multiple
supplying heat sources to study the influence of an
additional integrated heat source and the effects of reduced
supply temperatures on the network conditions. With the
developed model, we investigate the waste heat integration
into an existing district heating system at a German
research facility campus. Therefore, we test different
integrated waste heat shares to identify arising bottlenecks
and to check for the sufficient heat supply to the connected
consumers. Furthermore, we test the opportunity to
additionally lowering the supply temperatures in the
district heating network. The simulation results show that
waste heat integration is possible at the investigated
district heating system up to $40\%.$ However,
simultaneously lowering the supply temperature leads to
greater challenges as more bottlenecks arise and additional
buildings are affected by insufficient supply.},
