New features and improvements

  • GUI
    • Discontinuation of Graph 3 interface, replaced by Graph 4
    • Discontinuation of DrawHydro, replaced by Topology Viewer
    • Discontinuation of 32-bit version
  • Model
    • Hourly representation
      • Hydro commitment
      • Risk aversion curve (RAC) included in the model
      • Enhanced energy transference window of flexible demand modeling
    • The hydroelectric storage data now allows the definition of explicit limits for run-of-river plants, which are used in the chronological blocks, typical days and hourly representation for intra-stage modulation
      • Aiming to provide an automatic transition to the new representation, a data conversion process has been incorporated into the 17.3 interface:
        • The ror_operative_storage.dat file that contains the storage limits for hourly executions has been discontinued with the information being incorporated in the registry data
        • Run-of-river plants with 0 hm3 of useful storage had their limits recalculated according to its modulation capacity. The new limits are determined as Vmax = Vmin + 2 * (1 - regulation factor). Minimum storage Vmin remains unchanged.
      • Added option to allow automatic classification of hydroelectric plants based on its regularization capacity (useful storage and turbining capacity ratio, given in hours)
    • Typical days modeling
      • Intra-stage modulation for small storages (run-of-river, batteries, CSPs…)
      • Thermal operating constraints: generation ramps, minimum downtime, minimum uptime, maximum uptime

    • Operational status of DC link
    • Custom modeling
      • Generic interpolation constraints non-linear functions modeling
      • Generic variables, allowing its use with internal SDDP variables through generic linear and interpolation constraints
