Abstract [en]

If daily heat load variations could be eliminated in district heating-systems, it would make the operation of the district heating system less costly and more competitive . There would be several advantages in the operation such as:

  • Less use of expensive peak load power where often expensive fuels are used.
  • Less need for peak load power capacity.
  • Easier to optimize the operation that leads to higher conversion efficiencies.
  • Less need for maintenance because of more smooth operation of the plants

There are a number of ways to handle the daily variations of the heat load. Two often used are large heat storages or using the district heating network as temporary storage. If it would be possible to centrally control the customer substations, it would also be possible to use heavy buildings connected to the district heating system as heat storages.

To be able to find the best way to reduce or even eliminate the daily heat load variations, you need to understand the characteristics of the daily variations. This paper will describe a way of characterizing daily heat load variations in some Swedish district heating-systems.
