v1.2.2rc1

This release fixes several bugs related to the utilization factor, minimum service factor and the use of timeslices, which were affecting supply outputs and investment decisions. Most models are likely to be affected in some way by these fixes, although for many models these effects will be small. Models using the minimum service factor, and models with timeslice-level constraints (minimum service factor and utilization factor) are most likely to be strongly effected. Interested readers can follow the discussions in #518 and #368

v1.2.1rc1

The following guide should be read by all users upgrading from v1.2.0. Please read through carefully, as some of the changes may require you to modify your model input files or downstream analysis scripts.

Installation

If you have previously installed MUSE within a virtual environment, you can update MUSE by activating your virtual environment and running pip install --upgrade muse-os --pre

The --pre option is required as v1.2.1 is currently a pre-release.

If you installed MUSE using a different method, please consult the documentation.

Changes

Carbon budget module

• The bisection method has been fixed, as this was not working as expected before (#483, #484). Additionally, a number of default settings have been changed, and parameters renamed. Users must carefully check which parameters are specified in their settings files, as any unspecified parameters will revert to the new defaults. The main changes are as follows:
  • control_undershoot / control_overshoot: The default has been changed from True to False
  • method: The default has changed from fitting to bisection
  • method_options.refine_price: The default has changed from True to False
  • method_options.sample_size: This parameter no longer applies to the bisection algorithm, and won't be permitted when using that method. Please use method_options.max_iterations instead
  • method_options.tolerance and method_options.early_termination_count: New parameters for the bisection method

Please read the new documentation page in full before using a carbon budget

Default model

• A number of changes have been made to the default model that is generated with muse --model default --copy PATH. This is mostly to have a simpler model with a reduced set of output files (#461)

Tutorials

• The tutorials have been simplified and re-ordered (#470)
• A tutorial has been added explaining the use of a carbon budget (#486)
