Release notes

Unversioned

  • Use dev version of EMG for examples when running as part of tests, similar to PR #33 of EMB.

Version 0.9.0 (2024-05-24)

Update on function calls for dispatching on modeltype

  • Introduced modeltype as argument for all create and constraint functions.
  • Moved constraint on installed capacity to function constraints_capacity_installed to replicate the dispatch behaviour from EnergyModelsBase.

Version 0.8.5 (2024-05-24)

  • Update of dependencies and adjustment to changes in EnergyModelsBase v0.7.

Version 0.8.4 (2024-05-09)

  • Provided a contribution section in the documentation.
  • Fixed a link in the documentation for the examples.

Version 0.8.3 (2024-03-21)

  • Fixed a bug regarding accessing the field limit of a LimitedExchangeArea.
  • Moved all files declaring structures to a separate folder for improved readability.
  • Allow for jumping over TimeProfile checks also from EnergyModelsGeography.
  • Added possibility to provide a different type of JuMP.Model.

Version 0.8.2 (2024-03-04)

  • Fixed a bug when running the examples from a non-cloned version of EnergyModelsGeography.
  • This was achieved through a separate Project.toml in the examples.

Version 0.8.1 (2024-01-30)

  • Updated the restrictions on the fields of individual types to be more restrictive.

Version 0.8.0 (2023-12-19)

Adjusted to changes in EnergyModelsBase v0.6. These changes are mainly:

  • All fields of composite types are now lower case.
  • An extensive number of functions to access the individual fields were included, allowing for differing definitions of the individual nodes.
  • The GeoAvailability type does no longer require as input dictionaries for both input and output. Instead, it is now a single array corresponding to all resources.
  • New function getnodesinarea to extract nodes connected to the Availability node of an area.
  • Changed file structure for simplified understanding of the different types.

Version 0.7.1 (2023-06-16)

  • Updated the documentation based on the new format.

Version 0.7.0 (2023-06-06)

Switch to TimeStruct

  • Switched the time structure representation to TimeStruct.
  • TimeStruct is implemented with only the basis features that were available in TimeStructures. This implies that neither operational nor strategic uncertainty is included in the model.

Version 0.6.1 (2023-06-02)

  • Bugfix in linepacking to include multiplication with duration(t) for proper energy accounting

Version 0.6.0 (2023-05-30)

  • Changed the structure in which the extra field Data is included in the nodes.
  • It is changed from Dict{String, Data} to Array{data}.

Version 0.5.2 (2023-05-16)

  • Bugfix in the example which lead to a trivial solution in which no energy has to be converted.

Version 0.5.1 (2023-04-30)

Multiple smaller updates

  • Moved the example in user_interface.jl into an example folder.
  • Introduced checks that can be utlized to check transmission related data.
  • Fixed a bug for LimitedExchangeArea that utilized wrong values.

Version 0.5.0 (2023-04-27)

Added var and fixed opex for transmision modes

  • All TransmissionMode are updated to have fields for var and fixed opex.
  • Variables trans_opex_var and trans_opex_fixed, also constraints that describes these variables.
  • The function update_objective is updated in src\model.jl to add var and fixed opex to the objective function.

Additional changes

  • Constraints formulations are seperated into functions and moved to src\constraint_functions.jl, similar to how is is organized in EnergyModelsBase commit [26ad8740].
  • Compute functions are moved to seperate file src\compute_functions.jl.

Version 0.4.0 (2023-03-17)

Change of indexing

  • Variables are now indexed via the TransmissionMode and the time period instead of the using a SparseAxisArray and indexing via Transmission, time period, and TransmissionMode. This also improves model generation time.
  • This adjustment requires the declaration of a new instance for each usage of a TransmissionMode, see, e.g., the changes in scr\user_interface.jl.

Additional changes

  • Change of variable generation for individual transmission modes: Variable generation via the function variables_trans_mode(s) is adjusted to follow the concept introduced in EnergyModelsBase.
  • Move of the field Data from Transmission to TransmissionMode. This is required for the later application of dispatching in EnergyModelsInvestments.

Version 0.3.1 (2023-02-16)

Introduction of linepacking

  • Redefinition of PipelineMode as abstract type PipeMode and introduction of PipeSimple as a composite type corresponding to the previous PipelineMode.
  • Introduction of a simple linepacking implementation via the type `PipeLinepackSimple.
  • Change of Area to abstract type to be able to dispatch on areas.
  • Rewriting how functions for variable generation are called for easier introduction of variables for different TransmissionModes.

Version 0.3.0 (2023-02-02)

Adjustmends to updates in EnergyModelsBase

Adjustment to version 0.3.0, namely:

  • The removal of emissions from Node type definition that do not require them in all tests.
  • Removal of the type GlobalData and replacement with fields in the type OperationalModel in all tests.

Version 0.2.2 (2022-12-12)

Internal release

  • Updated Readme.
  • Renamed with common prefix.

Version 0.2.1 (2021-09-07)

Changes in naming

  • Major changes in both variable and parameter naming, check the commit message for an overview.
  • Introduction of bidrectional flow in transmission lines.

Version 0.2.0 (2021-08-02)

  • Defined structures for Areas, Transmission corridors and TransmissionModes.
  • Overloading of the default availability node balance to allow for export and import.
  • Added examples of plotting in maps.

Version 0.1.0 (2021-04-19)

  • Initial (skeleton) version.
