Stochastic/Multi-Outages: add CHP, modify outputs; CHP fixes

What's Changed

• Make outages output names not dynamic, add units to outages results, microgrid_upgrade_cost_fraction default to 0 by @hdunham in #202
• Add CHP to stochastic/multi- outages, some CHP tweaks for UI V3 by @Bill-Becker in #201
• Stochastic/Mulit-Outages: add CHP, modify outputs. Also CHP fixes. by @Bill-Becker in #205

Full Changelog: v0.28.1...v0.29.0

v0.29.0

Added

• Add CHP FuelUsed and FuelCost modeling/tracking for stochastic/multi-outages
• Add CHP outputs for stochastic/multi-outages

Changed

• Made outages output names not dynamic to allow integration into API
• Add missing units to outages results field names: unserved_load_series_kw, unserved_load_per_outage_kwh, generator_fuel_used_per_outage_gal
• Default Financial field microgrid_upgrade_cost_fraction to 0
• Add conditional logic to make CHP.min_allowable_kw 25% of max_kw if there is a conflicting relationship
• Iterate on calculating CHP heuristic size based on average heating load which is also used to set max_kw if not given: once size_class is determined, recalculate using the efficiency numbers for that size_class.

Fixed

• Fix non-handling of cost-curve/segmented techs in stochastic outages
• Fix issues with simulated_load.jl monthly heating energy input to return the heating load profile

Add emissions_profile function for API endpoint

What's Changed

• allow for creation of emissions_profile endpoint in API by @hdunham in #183
• emissions_profile function by @Bill-Becker in #200

Full Changelog: v0.28.0...v0.28.1

v0.28.1

Added

• emissions_profiles function, exported for external use as an endpoint in REopt_API for the webtool/UI

CHP class size and financial input output updates

Changed

• Changed Financial breakeven_cost_of_emissions_reduction_per_tonnes_CO2 to breakeven_cost_of_emissions_reduction_per_tonne_CO2
• Changed CHP.size_class to start at 0 instead of 1, consistent with the API, and 0 represents the average of all size_classs
• Change CHP.max_kw to be based on either the heuristic sizing from average heating load (if heating) or peak electric load (if no heating, aka Prime Generator in the UI)
  • The "big_number" for max_kw was causing the model to take forever to solve and some erroneous behavior; this is also consistent with the API to limit max_kw to a reasonable number

Added

• Added previously missing Financial BAU outputs: lifecycle_om_costs_before_tax, lifecycle_om_costs_after_tax, year_one_om_costs_before_tax

Fixed

• Fixed if statement to determing ElectricLoad "year" from && to ||, so that defaults to 2017 if any CRB input is used

Energy Resilience and Performance Tool

Added

• Energy Resilience Performance tool: capability to model limited reliability of backup generators and RE, and calculate survival probability metrics during power outages for a DER scenario
• Exported backup_reliability function to run the reliability based calculations

Changed

• Changed Generator inputs fuel_slope_gal_per_kwh and fuel_intercept_gal_per_hr to electric_efficiency_full_load and electric_efficiency_half_load to represent the same fuel burn curve in a different way consistent with CHP

Full Changelog: v0.25.0...v0.26.0

https://github.com/NREL/REopt.jl/blob/master/CHANGELOG.md

v0.26.0

Added

• Added has_stacktrace boolean which is returned with error messages and indicates if error is of type which contains stacktrace
• Constraint on wind sizing based on Site.land_acres
• New Wind input acres_per_kw, defaults to 0.03
• Descriptions/help text for many inputs and outputs
• Add and modify the GHP results to align with the existing/expected results from the v2 REopt_API
• Add CSV and DataFrames packages to REopt.jl dependencies

Changed

• Update REopt.jl environment to Julia v1.8
• Changed default year in ElectricLoad to be 2017 if using a CRB model and 2022 otherwise.
• Removed default year in URDBrate() functions, since year is always supplied to this function.
• In scenario.jl, change heating_thermal_load_reduction_with_ghp_kw to space_heating_thermal_load_reduction_with_ghp_kw to be more explicit
• Round Hot and Cold TES size result to 0 digits
• Use CoolProp to get water properties for Hot and Cold TES based on average of temperature inputs

Fixed

• Wind evaluations with BAU - was temporarily broken because of an unconverted year_one -> annual expected name
• Fixed calculation of year_one_coincident_peak_cost_before_tax in ElectricTariff results to correctly calculate before-tax value. Previously, the after-tax value was being calculated for this field instead.
• Fixed outage_simulator to work with sub-hourly outage simulation scenarios
• Fixed a bug which threw an error when providing time-series thermal load inputs in a scenario inputs .json.
• Fixed calculation of ["Financial"]["lifecycle_om_costs_before_tax_bau"] (was previously showing after tax result)
• Added bau_annual_emissions_tonnes_SO2 to the bau_outputs dict in results.jl and removed duplicate bau_annual_emissions_tonnes_NOx result

Removed

• Removed duplicate thermal_production_hot_water_or_steam field from the absorption chiller defaults response dictionary.
