                      emphasise the necessity to reduce carbon dioxide emissions
                      in the building sector. Therefore, various sustainable heat
                      sources should be used in existing district heating systems
                      to cover the heat demands of buildings. However, integrating
                      on-site heat sources into large existing district heating
                      networks could be challenging dueto temperature or capacity
                      limitations since such large district heating systems are
                      often supplied by large fossil-based heating plants. Most
                      sustainable heat sources that should be utilised in
                      districtheating systems differ in their geographical
                      locations or have limited heat capacities and, therefore,
                      cannot easily replace conventional heating plants. The
                      resulting difficulty of integrating limited heatsources into
                      large district heating networks could be tackled by
                      separating the existing network structure into two
                      independent heat distribution networks. In this study, we
                      present a developedframework that automatically recommends
                      which network parts of an existing district heating system
                      could be hydraulically separated in order to utilise a
                      present heat source that is not yet in use. Inthis way, a
                      second, standalone district heating system, supplied by the
                      utilised heat source, could be established. The framework
                      applies a community detection algorithm to the existing
                      district heatingnetwork to first identify communities in the
                      structure. Neighbouring communities are aggregated to larger
                      network areas, taking into account that these areas could be
                      supplied with the availableamount of heat. These network
                      areas are classified as possible areas for separation if the
                      shortest connection path to the utilised heat source is
                      within a certain distance. Subsequently, the
                      foundpossibilities for network separation are simulated to
                      test a feasible district heating operation and to evaluate
                      the environmental and economic impacts. The presented
                      framework is tested with a meshedand a spanning-tree network
                      structure. Overall, the developed framework presents an
                      approach to utilise present heat sources in separated
                      network structures by automatically identifying, testing
                      andevaluating possible network separations.},
