A lot of improvements 🎉

Important

There is a main breaking change in this version. The constructor of the class ElectricalNetwork has changed:

  • it accepts keyword arguments only.
  • it accepts the arguments lines, transformers and switches in replacement of the argument branches.
  • As a consequence,
    • the results method res_branches has been removed. Please use res_lines, res_transformers
      and res_switches methods instead.
    • the field branches does not exist anymore. Please use the fields lines, transformers and switches.
  • A wheel for Python 3.13 is available.
  • The wheels for Windows are now available. The problem was the same as the one of the
    issue 28551 of the Matplotlib repository.
  • #237 Improvements of the Sphinx configuration.
  • #262 Raise a proper error when a transformer is defined with null impedance.
  • #259 The cache of the license object was not reset after the activation of a new license key.
  • #258 #261 #263 Add basic plotting functionality in the new roseau.load_flow.plotting
    module. The plot_interactive_map function plots an electrical network on an interactive map using
    the folium library and the plot_voltage_phasors function plots the voltage phasors of a bus, load
    or source in the complex plane. The revamped plotting section of the documentation demonstrates the
    plotting functionalities available in Roseau Load Flow with examples.
  • #258 The documentation gained a new "advanced" section with a page on floating neutrals
    and a page on potential references.
  • #257 #252 Updates to the LineParameters class:
    • The method from_name_lv, deprecated since version 0.6, has been removed. It can be easily
      replaced by the from_geometry method.
    • The method from_name_mv is deprecated. A new method from_coiffier_model is added with the
      same functionality and more flexibility. The new method computes the ampacity of the line based
      on Coiffier's model and works with different numbers of phases.
  • #256 #250:
    • Accept scalar values for the powers, currents, impedances parameters of the load classes.
    • Add rlf.PositiveSequence, rlf.NegativeSequence and rlf.ZeroSequence vectors for easier
      creation of balanced quantities.
  • #255 Update the figures of loads and of voltage sources in the documentation to be compliant with the work
    of #249.
  • #254 #251 Allow passing multiple phases to potential references. The phase
    attribute of the PotentialRef is replaced by phases.
  • #249 #248 Accept scalar values for the voltages parameter of the VoltageSource class.
  • #247 Add connect_neutral parameter to the loads and sources constructor to specify if the
    neutral is to be connected to the bus's neutral or to be left floating. This allows loads connected
    to the same bus to have different neutral connections. The default behavior remains the same as
    before where the neutral is connected when the bus has a neutral and floating otherwise.
  • #246 Improvements to the rlf.converters module:
    • Fix series_phasor_to_sym function with series that have different phases per element.
    • Make calculate_voltages take array-like potentials.
    • Improve typing of several functions.
  • #245 #244 Fix the LineParameters.from_geometry method to not crash when passed
    unknown insulator type or None.
  • Add res_voltages to the VoltageSource class for symmetry with the other elements.
    res_voltages is always equal to the supplied voltages for a voltage source.
  • #243 Fix cross-sectional area of DGS line types created from line elements and special case
    invalid PwF line geographical coordinates table.
  • #240 Add tests for switches imported from DGS and improve warning and error messages.
  • #235 BREAKING CHANGE: The constructor of the class ElectricalNetwork has changed:
    • it accepts keyword arguments only.
    • it accepts the arguments lines, transformers and switches in replacement of the argument branches.
    • As a consequence,
      • the results method res_branches has been removed. Please use res_lines, res_transformers
        and res_switches methods instead.
      • the field branches does not exist anymore. Please use the fields lines, transformers and switches.
  • #235 Move the Switch class into its own file roseau/load_flow/models/switches.py.
  • #235 #239 The JSON file format number is upgraded to the version 2. All the files in version 0 or 1
    can still be read. Please upgrade them manually using the following code: 
    path = "my_json_file.json"
ElectricalNetwork.from_json(path).to_json(path)
  • #235 The method results_to_dict now accepts the keyword-only argument full which allows the export of all
    the results of an element.
  • #235 Solve a bug concerning the accessors to the flexible powers result of flexible power loads. An unwanted
    error was raised.
  • #235 Replace the occurrences of the str.find method by the str.index function.
  • #235 The method to_graph of the class ElectricalNetwork now retrieves a graph with additional data store
    in the edges depending on the edge type: line, transformer or switch.
  • #242 Add optional data to the TransformerParameters class: manufacturer, efficiency and range.
  • #242 Fixed a bug in the unit of q_min and q_max in the constructor of FlexibleParameter.
  • #242 Add equality operator for the classes FlexibleParameter, Control and Projection.
