Release Notes

Unversioned

  • Switched from Data to ExtensionData as described within EnergyModelsBase v0.9.1.
  • Minor fixes to the documentation and example comments.
  • Removed examples from test set as it somehow creates an error in the latest version on Ubuntu. This error is only present for a single test setup and cannot be reproduced locally.
  • Removed the folder submodels as the CHP model was moved to a new repository.

Version 0.1.2 (2025-06-10)

Bugfix

  • The function t_source(n::HeatPump) did result in an error. This was not tested previously and not used in the model. New tests are hence included for it.

Version 0.1.1 (2025-02-10)

  • Adjusted to EnergyModelsBase v0.9.0:
    • Increased version nubmer for EMB.
    • Model worked without adjustments.
    • Adjustments only required for simple understanding of changes.
  • Included updated DHPipe:
    • DHPIpe now follow a check.
    • The arguments for create_link were updated.
  • Renaming of test files to be consistent with other packages.

Version 0.1.0 (2024-12-18)

Initial version of the heat package within the EnergyModelsX framework.

Heat Pump

  • Developed a new HeatPump node based on RefNetworkNode.
  • Incorporates constraints on the input flow of a heat source and a driving force (electricity).
  • The underlying COP calculation is based on given profiles for sink and source temperature as well as a Carnot efficiency.

Thermal Energy Storage

  • Developed a ThermalEnergyStorage node.
  • Includes heat losses calculated by a given heat loss factor and the storage level of the previous time period.

District Heating Pipe

  • Developed a new type of link called DHPipe.
  • Incorporates a constant absolute heat loss between the input and the output of the link based on district heating temperature, ground temperature, pipe lenght and heat loss factor.
  • Requires a capacity and allows for investments.

HeatExchanger nodes

  • Developed a HeatExchanger node as parametric type.
  • The node can be used in combination with ResourceHeat for automatic calculation of the achievable energy recovery.
