v8.3.0

v8.3.0 (07/2022)

New features

• Adequacy patch - share the unsupplied energy according to the "local matching rule". This feature was contributed by RTE-i with support from RTE, ELIA and APG #657
• Add output variable "profit by cluster". This variable represents the difference between proportional costs and marginal costs in the area. It provides a partial answer to the question "what is the economic profit associated to a thermal cluster ?", excluding non-proportional (€/h) and startup costs (€/startup). #686
• Allow +/- infinity in binding constraint RHS, allowing the user to enable BCs only for some timesteps #631(*)
• Add option to enable the splitting of exported MPS files. This feature is intended to be used by Antares Xpansion.
• Add --list-solvers command-line argument, to list linear solvers available through OR-Tools
• Measure the execution duration for every computation step, store the durations in a dedicated file #546

(*) May not work with the Sirius solver. Consider using other solvers through OR-Tools

Bug fixes

• Fix segfault occuring when inter/intramodal correlation is enabled and TS width are inconsistent #694
• Fix logging of performed MC years when running jobs in parallel #680
• Fix a crash occuring in studies where an area contains 100+ thermal clusters (#753)
• Load & check prepro data only if needed (#754)
• Fix possible loss of data if adq-patch is disabled (#738)
• UI For property update for adq-patch mode, allow batch edit (#747)
• UI - Fix GUI freeze when using multiple map layers (#721)

For developers

• Display the git commit-id in the logs for debugging & diagnosis purposes #698
• Code cleaning in hydro heuristic #671
• Use antares-deps 2.0.2, which now excludes OR-Tools #684
• Fetch OR-Tools directly, allowing more flexibility on the flavor (XPRESS/Sirius/etc.) #684
• Code cleaning #663 #665 #666 #687 #725 #667 #668 #730

Misc. improvements

• Generate 2 assets in CentOS 7 : one that includes XPRESS, one that does not #689
• Upgrade examples 8.1 -> 8.3 (#733)
