REoptLite Changelog

v0.6.0

Improvements

  • Added multi-node (site) capability for PV and Storage
  • started documentation process using Github Pages and Documenter.jl
  • restructured outputs to align with the input structure, for example top-level keys added for ElectricTariff and PV in the outputs

v0.5.3

Improvements

  • compatible with Julia 1.5

v0.5.2

bug fixes

  • outage_simulator.jl had bug with summing over empty Any[]

Improvements

  • add optional microgrid_only arg to simulate_outages

v0.5.1

Improvements

  • added outage dispatch outputs and sped up their derivation
  • removed redundant generator minimum turn down constraint

v0.5.0

bug fixes

  • handle missing input key for year_one_soc_series_pct in outage_simulator
  • remove erroneous total_unserved_load = 0 output
  • dvUnservedLoad definition was allowing microgrid production to storage and curtailment to be double counted towards meeting critical load

Improvements

  • add unserved_load_per_outage output

v0.4.1

bug fixes

  • removed total_unserved_load output because it can take hours to generate and can error out when outage indices are not consecutive

Improvements

  • add @info for time spent processing results

v0.4.0

Improvements

  • add simulate_outages function (similar to REopt Lite API outage simulator)
  • removed MutableArithmetics package from Project.toml (since JuMP now has method for value(::MutableArithmetics.Zero))
  • added outage related outputs:
    • Generator_mg_kw
    • mg_Generator_upgrade_cost
    • mg_Generator_fuel_used
    • mg_PV_upgrade_cost
    • mg_storage_upgrade_cost
    • dvUnservedLoad array
    • max_outage_cost_per_outage_duration
  • allow VoLL values to be subtype of Real (rather than only Real)
  • add run_reopt method for scenario Dict

v0.3.0

Improvements

  • add separate decision variables and constraints for microgrid tech capacities
    • new Site input mg_tech_sizes_equal_grid_sizes (boolean), when false the microgrid tech capacities are constrained to be <= the grid connected tech capacities

bug fixes

  • allow non-integer outage_probabilities
  • correct total_unserved_load output
  • don't add_min_hours_crit_ld_met_constraint unless min_resil_timesteps <= length(elecutil.outage_timesteps)

v0.2.0

Improvements

  • add support for custom ElectricLoad loads_kw input
  • include existing capacity in microgrid upgrade cost
    • previously only had to pay to upgrade new capacity
  • implement ElectricLoad loads_kw_is_net and critical_loads_kw_is_net
    • add existing PV production to raw load profile if true
  • add min_resil_timesteps input and optional constraint for minimum timesteps that critical load must be met in every outage

bug fixes

  • enforce storage cannot grid charge

v0.1.1 Fix build.jl

deps/build.jl had a relative path dependency, fixed with an absolute path.

v0.1.0 Initial release

This package is currently under development and only has a subset of capabilities of the REopt Lite model used in the REopt Lite API. For example, the Wind model, tiered electric utility tariffs, and piecewise linear cost curves are not yet modeled in this code. However this code is easier to use than the API (only dependencies are Julia and a solver) and has a novel model for uncertain outages.
