energyRt 0.50.9-dev

New features & critical changes in the model code:

  • Weighting of time-slices in a subset has been revised and rewritten. Since this version, all variables with ‘slice’ dimension are not weighed for consistency of slice-level operation across sampled and non-sampled model runs.

  • Slice-weights can vary across model years.

  • All variables with ‘year’ dimension are not weighted to the interval lengths. 
    Exception:

    • cumulative variables (vSupReserveCum, etc.) which have to account the interval length for every milestone year. 

    • capacity variables (vTechCap, etc.) represent the state of the variable by the end of the period, including any accumulation or retirement of capacity over the interval of the milestone year.

  • New capacity variables (vTechNewCap, etc.) are given for a year. Period length (pPeriodLen) must be applied to the annual capacity additions (such as vTechNewCap) to get total new capacity of a process by the end of each period.

  • System costs have been regrouped by type (capital, fixed O&M, variable O&M, supply, taxes, subsidies) and by process type (technology, trade, storage, etc.) to facilitate the analysis of the cost structure. Total Costs equation has been rewritten to reflect the new cost structure.

    Bug fixes

  • Early retirement option (optimizeRetirment = TRUE) is corrected to exclude retirement of “new” technologies at the same time as their installation.

  • draw() method for ‘trade’ is fixed to exclude repeated arrows in the plot.

  • newCosts() is debugged, an example is added to the Utopia tutorial.

  • tsl2hour() fixed to be able identify n-digits hours (previously worked for 2 only).

    Miscellaneous

  • A new version (3) of the logo design idea (by DALL-E).

  • The code clean-up, testing, and documentation are in progress to comply with CRAN requirements.

  • Functions/method in progress: levcost() and report(),

  • add_weights and add_intervals arguments will be added to getData() function to add time-slice weights and interval lengths to the requested data if applicable.

energyRt 0.50.7-dev

  • Fixed a few stability issues in the draw() method.
  • Added “Hello World” example to the tutorial.
  • A new version of the logo design idea (by DALL-E).
  • The code clean-up and documentation are in progress to comply with CRAN requirements.
  • The very first draft of the package CRAN-like manual is added.
  • The version might be unstable due to ongoing changes.

energyRt 0.50.6-dev

  • draw() is drafted for all processes: ‘technology’, ‘export’, ‘import’, ‘supply’, ‘demand’, ‘trade’, ’storage
  • docs completed for main classes with examples.
  • code clean-up and documentation in progress.

energyRt 0.50.5-dev

  • draw() is rewritten based on ‘grid’ package, and is now a generic method.
  • added draw() methods for ‘technology’, ‘export’, and ‘import’ classes.
  • fixed several interface-level bugs introduced in 0.50.4-dev during clean-up and documentation.

energyRt 0.50.4-dev

  • Documentation of classes is in progress (~70% docs completed).
  • Logo-search has started! “logo” page added.
  • Website is reshaped, added new, not populated yet “articles”.
  • !!! Not Tested!!! Due to the ongoing changes in both documentation and functions/methods clean-up, the version may have “surprises” - tests are in progress.

energyRt 0.50.3-dev

  • Development version in the preparation for CRAN submission.
  • Added a NEWS.md file to track changes to the package.
  • Added functions to document classes from yaml file ‘classes.yaml’.
