Optimization

General

Unfeasible problem behaviour

enum Define the behavior of the simulator in case of an unfeasible problem.

  • warning-dry: Continue simulation.
  • warning-verbose: Continue simulation, but export the MPS of the unfeasible problem.
  • error-dry: Stop simulation.
  • error-verbose Stop simulation, and export the MPS of the unfeasible problem

Simplex optimization range

enum The simplex optimization range:

  • week
  • day

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 the 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.

Info

You can have more info on the impact of the optimization range in the heuristic for seasonal hydro pre-allocation.

Export MPS

enum Allow to choose which MPS files to export during the simulation.

  • none: Don't export any MPS file.
  • optim-1: Export only the MPS file from the first optimization.
  • optim-2: Export only the MPS file from the second optimization.
  • both: Export both MPS files from the first and second optimization.

Binding constraints

bool Whether to include binding constraints in the simulation.

Hurdle costs

bool Whether to include hurdle costs in the simulation.

Transmission capacities

enum Allow the user to override the transmission capacities on links.

  • 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 \(\infty\).
  • infinite-for-physical-links: override transmission capacities with \(\infty\) on physical links only.
  • null-for-physical-links: override transmission capacities with 0 on physical links only.

Thermal clusters

Thermal clusters min stable power

bool Whether to activate the constraint of minimum stable power for thermal units.

Thermal clusters min UD time

bool Whether to activate the constraint of minimum start-up time for thermal units.

Reserve

Day ahead reserve

bool Whether to activate day-ahead reserve constraints.

Primary reserve

bool Whether to activate primary reserve constraints.

Strategic reserve

bool Whether to activate strategic reserve constraints.

Spinning reserve

bool Whether to activate spinning reserve constraints.
