GenX - GenX.jl v0.4.0

Note: user guide "Porting a module from GenX v0.3.6 to GenX v0.4.0" available at this link.

What's Changed

This present version of GenX.jl through this new release introduces a few new modules and technologies. It also introduces a new version of the folder structure for case studies and a reformatted version of the input files for demand, reserves and resources. The documentation pages have also been updated to reflect these new changes as well as we have a much more logically consistent and user-friendly structure of organization of the documentation pages. We hope, this will cater better and more effectively, all kinds of users, whether developers/contributors, or energy modelers.

Added

  • Feature CO2 and fuel module (#536) Adds a fuel module which enables modeling of fuel usage via (1) a constant heat rate and (2) piecewise-linear approximation of heat rate curves. Adds a CO2 module that determines the CO2 emissions based on fuel consumption, CO2 capture fraction, and whether the feedstock is biomass.
  • Enable thermal power plants to burn multiple fuels (#586)
  • Feature electrolysis basic (#525) Adds hydrogen electrolyzer model which enables the addition of hydrogen electrolyzer demands along with optional clean supply constraints.
  • Add ability of storage to contribute to capacity reserves (#475)
  • Add Co-located VRE+Storage Module (#523)
  • Add output for dual of capacity constraint (#473)
  • Add PR template (#516)
  • Validation ensures that resource flags (THERM, HYDRO, LDS etc) are self-consistent (#513).
  • Maintenance formulation for thermal-commit plants (#556).
  • Add new tests for GenX: three-zone, multi-stage, electrolyzer, VRE+storage, piecewise_fuel+CO2, and TDR (#563 and #578).
  • Added a DC OPF method (#543) to calculate power flows across all lines
  • Added writeoperatingreservepricerevenue.jl to compute annual operating reserve and regulation revenue. and added the operating reserve and regulation revenue to net revenue (#611)
  • Add functions to compute conflicting constraints when model is infeasible if supported by the solver (#624).
  • New settings parameter, VirtualChargeDischargeCost to test script and VREStor example case. The PR 608 attempts to introduce this parameter as cost of virtual charging and discharging to avoid unusual results (#608).
  • New settings parameter, StorageVirtualDischarge, to turn storage virtual charging and discharging off if desired by the user (#638).
  • Add module to retrofit existing resources with new technologies (#600).
  • Formatted the code and added a format check to the CI pipeline (#673).
  • Add check when capital recovery period is zero and investment costs are non-zero in multi-stage GenX (#666)
  • Added condition number scaling added to objective function (#667)
  • Added versioned doc-pages for v0.3.6 and v0.4.0
  • Added a warning message in writecostsmultistage mentioning the approximate value of costs currently. (#680)

Fixed

  • Reserves have been renamed as OperationReserves in order to distinguish it from Capacity Reserve Margin (#641)
  • Generators_data.csv is not split into multiple different input files grouped together according to different resources (#612)
  • Assign correct investment cost per stage in objective function initialization for multi-stage runs (#530)
  • Fix name of FixedOMCostChargeperMWyr when reading from Generatorsdata in multistage code. (#533) Previously there was a typo in this in the multistage code that led to a silent bug, which affects outputs, for anyone running non-myopic multistage GenX with asymmetric storage.
  • Fix computation of cumulative minimum capacity retirements in multistage GenX (#514)
  • Fix access of eELOSSByZone expr before initialization (#541)
  • Correctly write unmet reserves (in reg_dn.csv) (#575)
  • Correctly scale total reserves column (in reg_dn.csv) (#594)
  • Add validation for Reg_Max and Rsv_Max columns in Generators_data.csv when MUST_RUN is set to 1 (#576)
  • Fix scaling of transmission losses in writetransmissionlosses.jl (#621)
  • Fix cost assignment to virtual storage charge/discharge - issue #604 (#608)
  • Fix modeling of hydro reservoir with long duration storage (#572).
  • Fix update of starting transmission capacity in multistage GenX
  • Fix write_status with UCommit = WriteShadowPrices = 1 (#645)
  • Fixed outputting capital recovery cost to 0 if the remaining number of years is 0 (#666)
  • Updated the docstring for the initializecostto_go function and adjusted the formula for the discount factor to reflect the code implementation (#672).
  • Fix writemultistage_cost.jl: add discount with OPEX multipliers to cUnmetPolicyPenalty (#679)
  • Fix DF calculation in DDP to make it more generic for variable length stages (#680)
  • Fix writepowerbalance.jl: add additional two columns ("VREStorageDischarge" and "VREStorageCharge") for VRE_STOR

Changed

  • Use addtoexpression! instead of the += and -= operators for memory performance improvements (#498).
  • Generally, 'demand' is now used where (electrical) 'load' was used previously (#397).
  • Load_data.csv is being renamed to Demand_data.csv. (#397)
  • Load_MW_z* columns in that file are renamed to Demand_MW_z*. (#397)
  • In Reserves.csv, Reg_Req_Percent_Load and Rsv_Req_Percent_Load are renamed to ..._Demand. (#397)
  • Load and LoadWeight keys in the time_domain_reduction_settings.yml file are renamed to Demand, DemandWeight. (#397)
  • The New_Build column in Generators_data.csv has been separated into two: New_Build and Can_Retire (#392). Values in each column are {0,1}.
  • Separate proprietary JuMP solvers from the GenX package. This allows users of Gurobi or CPLEX to use them without modifying the source code of the GenX package directly. This is a key step in publishing GenX as a proper Julia package. This does require change to the Run.jl files, to specify the solver. (#531)
  • In the examples, change RegMax and RsvMax of any MUST_RUN generators to 0. This mitigates but does not fully fix (#576).
  • Expressions of virtual charging and discharging costs in storageall.jl and vrestor.jl
  • The input file Generators_data.csv has been split into different files, one for each type of generator. The new files are: Thermal.csv, Hydro.csv, Vre.csv, Storage.csv, Flex_demand.csv, Must_run.csv, Electrolyzer.csv, and Vre_stor.csv. The examples have been updated, and new tests have been added to check the new data format (#612).
  • The settings parameter Reserves has been renamed to OperationalReserves, Reserves.csv to Operational_reserves.csv, and the .jl files contain the word reserves have been renamed to operational_reserves (#641).
  • New folder structure for a GenX case. The input files are now organized in the following folders: settings, policies, resources and system. The examples and tests have been updated to reflect this change.
  • New folder structure implemented for example_system. This folder now consists of nine separate folders each pertaining to a different case study example, ranging from the ISONE three zones, with singlestage, multistage, electrolyzers, all the way to the 9 bus IEEE case for running DC-OPF.
  • Pruned HiGHS solver settings to the necessary minimum (#668)
  • Changed deploydoc URL to GenX.jl (#662)

Deprecated

  • The above load keys, which generally refer to electrical demand, are being deprecated. Users should update their case files. For now this is done in a backward-compatible manner, and @info reminders are written to the log to prompt the user to update. "Load" now typically refers only to the transferrence of data from files to memory, except for a few places such as the common term "value of lost load" which refers to non-served demand (#397).
  • New_Build = -1 in Generators_data.csv: instead, use New_Build = 0 and Can_Retire = 0.
  • The matrix-style input of the grid for Network.csv is deprecated in favor a column-style input. Instead of columns z1, z2, ... with entries -1, 0, 1, use two columns: StartZone, EndZone (#591).

- Julia
Published by lbonaldo almost 2 years ago

GenX - GenX v0.4.0-rc

What's Changed

Added

  • Feature CO2 and fuel module (#536) Adds a fuel module which enables modeling of fuel usage via (1) a constant heat rate and (2) piecewise-linear approximation of heat rate curves. Adds a CO2 module that determines the CO2 emissions based on fuel consumption, CO2 capture fraction, and whether the feedstock is biomass.
  • Enable thermal power plants to burn multiple fuels (#586)
  • Feature electrolysis basic (#525) Adds hydrogen electrolyzer model which enables the addition of hydrogen electrolyzer demands along with optional clean supply constraints.
  • Add ability of storage to contribute to capacity reserves (#475)
  • Add Co-located VRE+Storage Module (#523)
  • Add output for dual of capacity constraint (#473)
  • Add PR template (#516)
  • Validation ensures that resource flags (THERM, HYDRO, LDS etc) are self-consistent (#513).
  • Maintenance formulation for thermal-commit plants (#556).
  • Add new tests for GenX: three-zone, multi-stage, electrolyzer, VRE+storage, piecewise_fuel+CO2, and TDR (#563 and #578).
  • Added a DC OPF method (#543) to calculate power flows across all lines
  • Added writeoperatingreservepricerevenue.jl to compute annual operating reserve and regulation revenue. Added the operating reserve and regulation revenue to net revenue (PR # 611)
  • Add functions to compute conflicting constraints when model is infeasible if supported by the solver (#624).
  • New settings parameter, VirtualChargeDischargeCost to test script and VREStor example case. The PR 608 attempts to introduce this parameter as cost of virtual charging and discharging to avoid unusual results (#608).
  • New settings parameter, StorageVirtualDischarge, to turn storage virtual charging and discharging off if desired by the user (#638).
  • Add module to retrofit existing resources with new technologies (#600).

Fixed

  • Set MUSTRUN=1 for RealSystemExample/smallhydro plants (#517). Previously these plants had no resource flag set, and so they did not contribute to the power balance. As these plants are now useful, the objective in these cases is slightly lower.
  • Assign correct investment cost per stage in objective function initialization for multi-stage runs (#530)
  • Fix name of FixedOMCostChargeperMWyr when reading from Generatorsdata in multistage code. (#533) Previously there was a typo in this in the multistage code that led to a silent bug, which affects outputs, for anyone running non-myopic multistage GenX with asymmetric storage.
  • Fix computation of cumulative minimum capacity retirements in multistage GenX (#514)
  • Fix access of eELOSSByZone expr before initialization (#541)
  • Correctly write unmet reserves (in reg_dn.csv) (#575)
  • Correctly scale total reserves column (in reg_dn.csv) (#594)
  • Add validation for Reg_Max and Rsv_Max columns in Generators_data.csv when MUST_RUN is set to 1 (#576)
  • Fix scaling of transmission losses in writetransmissionlosses.jl (#621)
  • Fix cost assignment to virtual storage charge/discharge - issue #604 (#608)
  • Fix modeling of hydro reservoir with long duration storage (#572).
  • Fix update of starting transmission capacity in multistage GenX
  • Fix write_status with UCommit = WriteShadowPrices = 1 (#645)

Changed

  • Use addtoexpression! instead of the += and -= operators for memory performance improvements (#498).
  • Generally, 'demand' is now used where (electrical) 'load' was used previously (#397).
  • Load_data.csv is being renamed to Demand_data.csv.
  • Load_MW_z* columns in that file are renamed to Demand_MW_z*.
  • In Reserves.csv, Reg_Req_Percent_Load and Rsv_Req_Percent_Load are renamed to ..._Demand.
  • Load and LoadWeight keys in the time_domain_reduction_settings.yml file are renamed to Demand, DemandWeight.
  • The New_Build column in Generators_data.csv has been separated into two: New_Build and Can_Retire (#392). Values in each column are {0,1}.
  • Separate proprietary JuMP solvers from the GenX package. This allows users of Gurobi or CPLEX to use them without modifying the source code of the GenX package directly. This is a key step in publishing GenX as a proper Julia package. This does require change to the Run.jl files, to specify the solver. (#531)
  • In the examples, change RegMax and RsvMax of any MUST_RUN generators to 0. This mitigates but does not fully fix (#576).
  • Expressions of virtual charging and discharging costs in storageall.jl and vrestor.jl
  • The input file Generators_data.csv has been split into different files, one for each type of generator. The new files are: Thermal.csv, Hydro.csv, Vre.csv, Storage.csv, Flex_demand.csv, Must_run.csv, Electrolyzer.csv, and Vre_stor.csv. The examples have been updated, and new tests have been added to check the new data format (#612).
  • The settings parameter Reserves has been renamed to OperationalReserves, Reserves.csv to Operational_reserves.csv, and the .jl files contain the word reserves have been renamed to operational_reserves (#641).
  • New folder structure for a GenX case. The input files are now organized in the following folders: settings, policies, resources and system. The examples and tests have been updated to reflect this change.

  • The above load keys, which generally refer to electrical demand, are being deprecated. Users should update their case files. For now this is done in a backward-compatible manner, and @info reminders are written to the log to prompt the user to update. "Load" now typically refers only to the transferrence of data from files to memory, except for a few places such as the common term "value of lost load" which refers to non-served demand (#397).
  • New_Build = -1 in Generators_data.csv: instead, use New_Build = 0 and Can_Retire = 0.
  • The matrix-style input of the grid for Network.csv is deprecated in favor a column-style input. Instead of columns z1, z2, ... with entries -1, 0, 1, use two columns: StartZone, EndZone (#591).

What's Changed

The major updates to the v0.3.1 patch release are the following: 1. Addition of HiGHS as the default solver (HiGHS is open-source, free/non-commercial, and a fast solver as long as LP problems are being solved) 2.

GenX - GenX version v0.3.0

GenX version 0.3.0 Release Notes

In this version, we have upgraded GenX to version v0.3.0. To run GenX 0.3.0, we recommend Julia language version 1.6.x series along with JuMP 0.21.x series (all the environment dependencies have been updated to the most recent compatible versions as well). The following are the salient features that have been added in this version release:

  • Added Dual Dynamic Programming (DDP) Multi-stage capacity expansion feature to GenX: This is the major highlight and most important new feature added to GenX in version 0.3.0. Addition of the DDP now allows GenX to carry out multi stage and multi year look-ahead capacity expansion planning into the future in a most rigorous mathematical framework.
  • Vectorization of output writing to enhance the speed of generating results files.
  • Revised and updated "Method of Morris" for sophisticated sensitivity analyses studies (along with previously created "Modeling to Generate Alternatives (MGS)" analysis).
  • Bug-fixes and refinement of modularization of the different policy modules like co2cap, capreservemargin, minimumcapacity_requirement etc., for ease and convenience for adding new technologies by the users.

GenX - GenX version v0.2.0

In this version, we have once again upgraded GenX to version v0.2.0. This version (like v0.1.0) also runs with Julia language versions 1.5.x and 1.6.x series along with JuMP 0.21.x series (all the environment dependencies have been updated to the most recent compatible versions as well). The following are the salient features that have been added in this version release:

  • Added "Method of Morris" for sophisticated sensitivity analyses studies (along with previously created "Modeling to Generate Alternatives (MGS)" analysis).
  • Added SCIP as an open source solver option, which has a much superior performance, on, especially mixed integer programming problem instances.
  • Modularized the different policy modules like co2cap, capreservemargin, minimumcapacity_requirement etc., for ease and convenience for adding new technologies by the users.

Just like before, we have also fixed many of the bugs that were present in the earlier release. Version v0.1.0 is still there in the old version branch. The older release before v0.1.0 is still on GitHub on the branch old_version (the older release runs with Julia 1.3.x and 1.4.x series and with older versions of environment dependencies).

GenX - GenX version v0.1.0

In this version, we have upgraded GenX, so that it can be run with the two most recent Julia language versions, namely 1.5.x and 1.6.x series along with JuMP 0.21.x series (all the environment dependencies have been updated to the most recent compatible versions as well). We have also fixed many of the bugs that were present in the earlier release. The older release is still on GitHub on the branch old_version (the older release runs with Julia 1.3.x and 1.4.x series and with older versions of environment dependencies).
