Abstract:
When planning grid-connected heat supply concepts, network operators and planning offices rely on the use of software applications or standard load profile methods to generate load profiles for the design of storage and heat generation systems. This is especially important if network parameters, such as the heat demand of customers, the number of consumers or the network temperatures are expected to change in the future. Therefore, it is relevant to determine how distinctive the deviations between the measured heat load and the load profiles generated by different software applications are and how strongly these differences affect the dimensioning and operation of heating networks. Annual load profiles of the individual consumers and the entire grid are created in two different software applications for an anonymized heating grid. In addition to the actual state of the heat grid, load profiles are also created for possible future changes in the heat network. The investigated software applications both determined an approximately accurate heat duration curve, which represents a major part of the peak and base load relatively precisely, but yielded an underestimation of the absolute peak load, as well as an overestimation in the partial load range. Depending on the network change investigated, the results of the software applications deviate to a varying extent from the original simulation.
