    Export MPS only for the first step of the optimization.

  • OPTIM2 –

    Export MPS only for the second step of the optimization.

  • BOTH_OPTIMS –

    Export MPS for both steps of the optimization.

Update optimization parameters.

See the class OptimizationParameters for details of the parameters.

OptimizationTransmissionCapacities

Optimization of transmission capacities.

Allow the user to override the transmission capacities on links.

Attributes:

  • LOCAL_VALUES –

    Use the local property for all links, including physical links (no override).

  • NULL_FOR_ALL_LINKS –

    Override all transmission capacities with 0.

  • INFINITE_FOR_ALL_LINKS –

    Override all transmission capacities with inf.

  • NULL_FOR_PHYSICAL_LINKS –

    Override transmission capacities with 0 on physical links only.

  • INFINITE_FOR_PHYSICAL_LINKS –

    Override transmission capacities with inf on physical links only.

SimplexOptimizationRange

Simplex optimization range.

In the formulation of the optimal hydro-thermal unit-commitment and dispatch problem, the reference hydro energy \(HIT\) used to set the right hand sides of hydro constraints depends on the value chosen for this parameter, and is defined as follows: - day: for each day d of week \(\omega\) : \(HIT = W_d^2\) - week: for week \(\omega\): \(HIT = \sum_{d\in \omega}{W_d^2}\)

Weekly optimization performs a more refined unit-commitment, especially when unit_commitment_mode is set to accurate.

Attributes:

  • DAY –
  • WEEK –

UnfeasibleProblemBehavior

Define the behaviour of the simulator in case of an unfeasible problem.

Attributes:

  • WARNING_DRY –

    Continue simulation.

  • WARNING_VERBOSE –

    Continue simulation, but export the MPS file of the unfeasible problem.

  • ERROR_DRY –

    Stop simulation.

  • ERROR_MPS –

    Stop simulation, and export the MPS file of the unfeasible problem.
