v0.4.5

GenX v0.4.5

Patch Release

Added

• New resource type: Allam Cycle with Oxygen Storage (#772).
• Caching of derating_factor to improve performance in model generation (#834).
• Default option, "EnableJuMPDirectMode", to build the model more efficiently. Models running with, non-default, solvers Cbc and Clp will fail unless "EnableJuMPDirectMode" is set to false (#835).
• Improve @expressions performance by pre-processing sets (#815).

Fixed

• Fix call to get_retirement_stage by casting lifetime to integer (#840).
• Modify storage_all.jl to prevent micro-charging/discharging close to capacity (#836).

Changed

• Replace += and -= with add_to_expression! and add_similar_to_expression! in several modules to improve performance (#826).
• Separate myopic logic and DDP logic in the GenX multi-stage code into distinct functions (#810).
