Decision-making process for addressing bottleneck problems in district heating networks
(2019) In International Journal of Sustainable Energy Planning and Management 20(2019). p.37-50- Abstract
Lower system temperatures in district heating (DH) grids are important factors for system efficiency. Lower system temperatures lead, for example, to lower heat losses and higher production unit efficiency. One obstacle to lower supply temperatures are so-called bottlenecks in DH networks. Bottlenecks are areas in DH networks of very low differential pressure, which makes it difficult to supply them with sufficient heat. There are many potential solutions to bottlenecks. However, the current decision-making process generally does not include every potential bottleneck solution and also often does not include every important factor that affects the outcome. The aim of this study is to propose a structured and general modus operandi, in... (More)
Lower system temperatures in district heating (DH) grids are important factors for system efficiency. Lower system temperatures lead, for example, to lower heat losses and higher production unit efficiency. One obstacle to lower supply temperatures are so-called bottlenecks in DH networks. Bottlenecks are areas in DH networks of very low differential pressure, which makes it difficult to supply them with sufficient heat. There are many potential solutions to bottlenecks. However, the current decision-making process generally does not include every potential bottleneck solution and also often does not include every important factor that affects the outcome. The aim of this study is to propose a structured and general modus operandi, in order to identify the best bottleneck solution for a specific situation. In this study we conducted analyses of previous bottleneck studies, workshops and interviews. The results show a decision-making process developed to be a tool when choosing a bottleneck solution. Coupled to the decision-making process, a summary of the advantages and disadvantages of different factors and bottleneck solutions is presented, as well as a description of a real case in which the decision-making process is used.
