001005146 520__ $$aA 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 has to be studied in advance in order to avoid difficulties during network operation and to guarantee the required supply of heat to all connected buildings. The integration possibilities mainly depend on the network topology or rather on the geographical location of the additional heat source and the installed pipes in this area.The situation of implementing a new waste heat source into an existing district heating system arises at the Forschungszentrum Jülich, Germany, as a new supercomputer on the campus emits waste heat at a low-temperature level of around 44°C. To make sensible use of the generated heat, its usage in the high-temperature district heating system of the campus, which supplies heat to the campus buildings at supply temperatures of 95-132°C, is examined.In this case, the temperature level of the waste heat is centrally upgraded by a heat pump. In this work, we focus on the operational behaviour of the district heating network and study the influence of the additional integrated heat source on the network conditions. Therefore, we extend the existing district heating simulation model in Modelica to investigate the district heating operation with multiple heat sources.We test two different control strategies of the additional integrated heat source to investigate their influences on network operating conditions. With the first control strategy, the waste heat source supplies a constant amount of heat, while with the second control strategy, a constant share of the total heat demand is supplied by the waste heat source. In addition, we also simulate different supply temperatures to increase the operation efficiency and to study the impact of lower temperatures on network operation.
