Version 0.7.0-alpha

[benoit9126]

Important

Starting with version 0.7.0, Roseau Load Flow will no longer be supplied as a SaaS. The software will
be available as a standalone Python library. Please contact us at [email protected] in order to get a license key.

• Potentials propagation #168 BUG: Non-physical power flow solution returned when simulating MV/LV network #166 Fix initial potentials' propagation.
• Add lines catalogue and get_catalogue method #167 ENH: Add a catalogue of LineParameters (similar to TransformerParameters) #161 Add a catalogue of lines using the IEC standards. You can use the method
  LineParameters.get_catalogue() to get a data frame of the available lines and the method
  LineParameters.from_catalogue() to create a line from the catalogue. Several line types, conductor
  material, and insulation types have been updated. Physical constants have been updated to match the
  IEC standards where applicable.
• Add lines catalogue and get_catalogue method #167 The class LineParameters now takes optional arguments line_type, conductor_type,
  insulator_type and section. These parameters are accessible as properties. They are filled
  automatically when creating a line from the catalogue or from a geometry.
• Add lines catalogue and get_catalogue method #167 Replace all print_catalogue() methods by get_catalogue() methods that return a
  data frame instead of printing the catalogue to the console.
• Add lines catalogue and get_catalogue method #167 Enumeration classes no longer have a from_string method, you can call the enumeration
  class directly with the string value to get the corresponding enumeration member. Case-insensitive
  behavior is preserved.
• Add lines catalogue and get_catalogue method #167 ENH: LineParameters alternative constructors #122 Add checks on line height and diameter in the LineParameters.from_geometry()
  alternative constructor. This method will try to guess a default conductor and insulation type if
  none is provided.
• Fix res_transformers returning an empty dataframe #163 BREAKING CHANGE: roseau-load-flow is no longer a SaaS project. Starting with version
  0.7.0, the software is distributed as a standalone Python package. You need a license to use it for
  commercial purposes. See the documentation for more details. This comes with a huge performance
  improvement but requires a breaking change to the API:
  • The ElectricalNetwork.solve_load_flow() method no longer takes an auth argument.
  • To activate the license, you need to call roseau.load_flow.activate_license("MY LICENSE KEY")
    or set the environment variable ROSEAU_LOAD_FLOW_LICENSE_KEY (preferred) before calling
    ElectricalNetwork.solve_load_flow(). More information in the documentation.
  • Several methods on the FlexibleParameter class that previously required auth are changed. Make
    sure to follow the documentation to update your code.
• Fix res_transformers returning an empty dataframe #163 BUG: res_transformers attribute is an empty Dataframe #158 Fix ElectricalNetwork.res_transformers returning an empty dataframe
  when max_power is not set.
• Fix res_transformers returning an empty dataframe #163 Several unused exception codes were removed. An EMPTY_NETWORK code was added to indicate
  that a network is being created with no elements.
• Fix res_transformers returning an empty dataframe #163 Remove the ElectricalNetwork.res_info attribute. ElectricalNetwork.solve_load_flow() now
  returns the tuple (number of iterations, residual).
• Fix res_transformers returning an empty dataframe #163 Remove the Bus.clear_short_circuits() and ElectricalNetwork.clear_short_circuits()
  methods. It is currently not possible to clear short-circuits from the network.
• Fix res_transformers returning an empty dataframe #163 Improve performance of network creation and results access.
• Fix res_transformers returning an empty dataframe #163 Attributes phases and bus are now read-only on all elements.
• Update to Python 3.10 #151 Require Python 3.10 or newer.
