The algorithm works iteratively: it solves the master problem, fixes that solution in the subproblems, solves the subproblems, and then returns cuts (typically dual information) back to the master problem that refine the solution space. This process of passing information (primal and dual variables) between the master and subproblems continues until an upper and lower bound converge. For further details on Benders decomposition in capacity expansion models, please see this paper by [Jacobson et al.](https://pubsonline.informs.org/doi/abs/10.1287/ijoo.2023.0005) ([preprint](https://arxiv.org/abs/2302.10037)) or this paper by [Pecci and Jenkins](https://ieeexplore.ieee.org/abstract/document/10829583) ([preprint](https://arxiv.org/abs/2403.02559)). The mathematical formulation for the capacity expansion model and how it is decomposed is shown in more detail in the [Benders Model Overview](@ref). + +Benders decomposition can be especially useful when the problem can be decomposed with several independent subproblems. This is because the subproblems can each be solved in parallel after the master problem solve is complete. GenX exploits this ability by decomposing the problem in time and solving with representative time periods, such that the linking between time periods is only captured inside the master problem. This allows for each representative period to be solved independently in parallel during a single iteration of Benders. For this reason, it is generally advised that the user provide their data as representative periods or to use the time domain reduction capability of GenX, which automatically creates the representative periods for use in Benders. + + +Benders decomposition is accessed by setting `Benders: 1` in the `genx_settings.yml` file. In addition, the user must planning problem and subproblem solver settings as `[solver_name]_benders_planning_settings.yml` and `[solver_name]__benders_subprob_settings.yml` as well as a settings files for Benders called `benders_settings.yml`. Internally, GenX calls [MacroEnergySolvers.jl](https://github.com/macroenergy/MacroEnergySolvers.jl/tree/main) to run the Benders algorithm. The settings which can be passed to the `benders_settings.yml` file are shown in the following table. + +|**Parameter** | **Allowed Values** |**Description**| +| :------------ | :-----------|:-----------| +| MaxIter | $\in \mathbb{Z}_+$ | Maximum number of Benders iterations +| MaxCpuTime | $\ge 0$ | Wall-clock time limit in seconds| +| ConvTol | $\in (0, 1]$| Relative optimality-gap convergence tolerance (\|UB - LB\| / \|UB\| ≤ BD_ConvTol → converged) | +| StabParam | $\in [0, 1]$ | Level-set stabilisation parameter; 0.0 = disabled | +| StabDynamic | $\{true, false\}$ | Dynamic (Magnanti–Wong / in-out) stabilisation; false = disabled | +| IntegerInvestment | $\{true, false\}$ | Investment variable type; false = continuous (LP relaxation), true = integer (MILP master problem)| +| Distributed | $\{true, false\}$ | Whether to distribute subproblems to remote workers | +| ExpectFeasibleSubproblems | $\{true, false\}$ | # If true, skip feasibility cuts (assumes subproblems are always feasible); safe to leave false| + +Note that the stabilization/regularization scheme used in MacroEnergySolvers.jl is turned on when when StabParam is greater than zero. For the regularization scheme to work, the planning problem solver must use an interior point method without crossover. Stabilization is a process in Benders where the master problem can choose less extreme solutions that are on the interior of the feasible set (see [Pecci and Jenkins](https://ieeexplore.ieee.org/abstract/document/10829583)). A challenge of Benders is that, especially at early iterations, the master problem chooses solutions that result in high costs in the subproblems (e.g., at the first iteration, Benders typically chooses to build nothing in the planning level because it is trying to minimize cost without knowledge of the operations) which results in poor cuts. The stabilization scheme generally allows the master to choose solutions that are less extreme and can result in stronger cuts early on. + + +### Note on Convergence +How well Benders Decomposition solves a problem is dependent on many factors, and there are several ongoing research projects around the world to improve the performance of Benders Decomposition. There is no guarantee on the number of iterations it will take to reach a specific tolerance. Algorithm performance is driven by many things, and modeling decisions can strongly impact convergence speed. Generally speaking, Benders Decomposition may or may not outperform solving the monolithic problem, and it is generally best when the monolithic is becoming very slow or intractable to solve. \ No newline at end of file diff --git a/docs/src/User_Guide/model_configuration.md b/docs/src/User_Guide/model_configuration.md index a6f7ba3b51..d5fd15e90e 100644 --- a/docs/src/User_Guide/model_configuration.md +++ b/docs/src/User_Guide/model_configuration.md @@ -43,6 +43,9 @@ The following tables summarize the model settings parameters and their default/p ||1 = Scaling is activated. | ||0 = Scaling is not activated. | |ObjScale| Parameter value to scale the objective function during optimization.| +|Benders| Flag on whether to use [Benders Decomposition](https://en.wikipedia.org/wiki/Benders_decomposition) or not | +|| 0 = Monolithic formulation for solving model| +|| 1 = Benders Decomposition applied to solve the model | |MultiStage | Model multiple planning stages | ||1 = Model multiple planning stages as specified in `multi_stage_settings.yml` | ||0 = Model single planning stage | diff --git a/docs/src/developer_guide.md b/docs/src/developer_guide.md index bca5d37293..5ed7927196 100644 --- a/docs/src/developer_guide.md +++ b/docs/src/developer_guide.md @@ -364,4 +364,13 @@ DocTestSetup = nothing ```@autodocs Modules = [GenX] Pages = ["model/expression_manipulation.jl"] -``` \ No newline at end of file +``` + +## Benders Decomposition Code Structure +To support Benders decomposition, several design decisions were made to the GenX source code, which we outline here. + +The algorithm itself is accessed through the package [MacroEnergySolvers.jl](https://github.com/macroenergy/MacroEnergySolvers.jl/tree/main).

The script `src/model/capacity_decisions.jl` is Benders specific and is called on the operations level problem if Benders is being used. This file adds copies of all of the complicating variables to the subproblem. This is essential as the GenX source code often assumes these variables already exist. MacroEnergySolvers will detect the complicating variables by matching the names of the variables on the master (i.e., planning) model with the subproblem(s). + +Several scripts are available in the `src/benders` directory for running Benders. These include a file for constructing the planning problem and the subproblems, and functions for updating the inputs data to work with Benders. \ No newline at end of file From b2b7ebbc516867c01c7aa9119fbf3286639611a6 Mon Sep 17 00:00:00 2001 From: David Cole Date: Fri, 12 Jun 2026 13:49:18 -0400 Subject: [PATCH 06/28] Debugged VRE Stor with LDES and non LDES --- src/benders/benders_regularization.jl | 30 - src/benders/benders_subproblems.jl | 4 - src/benders/benders_utility.jl | 8 +- src/benders/results.jl | 30 - src/case_runners/case_runner.jl | 23 +- src/configure_settings/configure_settings.jl | 3 +- src/model/capacity_decisions.jl | 1 + src/model/core/ldes_slack.jl | 4 +- src/model/generate_model.jl | 16 +- .../resources/vre_stor/investment_vre_stor.jl | 166 ++-- src/model/resources/vre_stor/vre_stor.jl | 774 ++++-------------- src/write_outputs/benders_output_utilities.jl | 695 ---------------- src/write_outputs/write_benders_output.jl | 5 +- 13 files changed, 259 insertions(+), 1500 deletions(-) delete mode 100644 src/benders/benders_regularization.jl delete mode 100644 src/benders/results.jl delete mode 100644 src/write_outputs/benders_output_utilities.jl diff --git a/src/benders/benders_regularization.jl b/src/benders/benders_regularization.jl deleted file mode 100644 index d30b23d49e..0000000000 --- a/src/benders/benders_regularization.jl +++ /dev/null @@ -1,30 +0,0 @@ - -function solve_int_level_set_problem(EP::Model,planning_variables::Vector{String},planning_sol::NamedTuple,LB,UB,γ) - - @constraint(EP,cLevel_set,EP[:eObj] + sum(EP[:vTHETA])<=LB+γ*(UB-LB)) - - @objective(EP,Min, 0*sum(EP[:vTHETA])) - - optimize!(EP) - - if has_values(EP) - - planning_sol = (;planning_sol..., inv_cost=value(EP[:eObj]), values=Dict([s=>value(variable_by_name(EP,s)) for s in planning_variables]), theta = value.(EP[:vTHETA])) - - else - - if !has_values(EP) - @warn "the interior level set problem solution failed" - else - planning_sol = (;planning_sol..., inv_cost=value(EP[:eObj]), values=Dict([s=>value(variable_by_name(EP,s)) for s in planning_variables]), theta = value.(EP[:vTHETA])) - end - end - - - delete(EP,EP[:cLevel_set]) - unregister(EP,:cLevel_set) - @objective(EP,Min, EP[:eObj] + sum(EP[:vTHETA])) - - return planning_sol - -end diff --git a/src/benders/benders_subproblems.jl b/src/benders/benders_subproblems.jl index 6b85888afe..d074b703db 100644 --- a/src/benders/benders_subproblems.jl +++ b/src/benders/benders_subproblems.jl @@ -1,6 +1,5 @@ function generate_operation_subproblem(setup::Dict, inputs::Dict, OPTIMIZER::MOI.OptimizerWithAttributes) - ## Start pre-solve timer presolver_start_time = time() EP = Model(OPTIMIZER) @@ -22,12 +21,9 @@ function generate_operation_subproblem(setup::Dict, inputs::Dict, OPTIMIZER::MOI presolver_time = time() - presolver_start_time return EP - - end function init_subproblem(setup::Dict, inputs::Dict, OPTIMIZER::MOI.OptimizerWithAttributes,planning_variables::Vector{String}) - EP = generate_operation_subproblem(setup, inputs, OPTIMIZER) set_silent(EP) diff --git a/src/benders/benders_utility.jl b/src/benders/benders_utility.jl index 53cfc4bc4e..a6a46df64d 100644 --- a/src/benders/benders_utility.jl +++ b/src/benders/benders_utility.jl @@ -21,6 +21,12 @@ function separate_inputs_subperiods(inputs::Dict) for ks in keys(inputs["fuel_costs"]) inputs_all[w]["fuel_costs"][ks] = inputs["fuel_costs"][ks][Tw];

The first of these two constraints enforces storage inventory balance for interior time - steps $(t \in \mathcal{T}^{interior})$, while the second enforces storage balance constraint for the initial time step $(t \in \mathcal{T}^{start})$: -```math -\begin{aligned} - & \Gamma_{y,z,t} = \Gamma_{y,z,t-1} - \frac{\Theta^{dc}_{y,z,t}}{\eta_{y,z}^{discharge,dc}} - \frac{\Theta^{ac}_{y,z,t}}{\eta_{y,z}^{discharge,ac}} + \eta_{y,z}^{charge,dc} \times \Pi^{dc}_{y,z,t} + \eta_{y,z}^{charge,ac} \times \Pi^{ac}_{y,z,t} \\ - & - \eta_{y,z}^{loss} \times \Gamma_{y,z,t-1} \quad \forall y \in \mathcal{VS}^{stor}, z \in \mathcal{Z}, t \in \mathcal{T}^{interior}\\ - & \Gamma_{y,z,t} = \Gamma_{y,z,t+\tau^{period}-1} - \frac{\Theta^{dc}_{y,z,t}}{\eta_{y,z}^{discharge,dc}} - \frac{\Theta^{ac}_{y,z,t}}{\eta_{y,z}^{discharge,ac}} + \eta_{y,z}^{charge,dc} \times \Pi^{dc}_{y,z,t} + \eta_{y,z}^{charge,ac} \times \Pi^{ac}_{y,z,t} \\ - & - \eta_{y,z}^{loss} \times \Gamma_{y,z,t+\tau^{period}-1} \quad \forall y \in \mathcal{VS}^{stor}, z \in \mathcal{Z}, t \in \mathcal{T}^{start} -\end{aligned} -``` +Creates storage SOC and charge/discharge variables (DC/AC), adds variable O&M costs, +and builds SOC balance expressions for interior and start-of-subperiod timesteps. -This constraint limits the volume of energy stored at any time, $\Gamma_{y,z,t}$, to be less than the installed energy storage capacity, $\Delta^{total, energy}_{y,z}$. -```math -\begin{aligned} - & \Gamma_{y,z,t} \leq \Delta^{total, energy}_{y,z} & \quad \forall y \in \mathcal{VS}^{stor}, z \in \mathcal{Z}, t \in \mathcal{T} -\end{aligned} -``` +SOC recursion is of the form: -The last constraint limits the volume of energy exported from the grid to the storage at any time, $\Pi_{y,z,t}$, to be less than the electricity charged to the energy storage component, $\Pi_{y,z,t}^{ac} + \frac{\Pi^{dc}_{y,z,t}}{\eta^{inverter}_{y,z}}$. ```math -\begin{aligned} - & \Pi_{y,z,t} = \Pi_{y,z,t}^{ac} + \frac{\Pi^{dc}_{y,z,t}}{\eta^{inverter}_{y,z}} -\end{aligned} +vS_{y,t} = vS_{y,t-1}(1-\eta^{loss}_y) + - \frac{P^{dc,dis}_{y,t}}{\eta^{dc,dis}_y} + - \frac{P^{ac,dis}_{y,t}}{\eta^{ac,dis}_y} + + \eta^{dc,cha}_y P^{dc,cha}_{y,t} + + \eta^{ac,cha}_y P^{ac,cha}_{y,t} ``` -The next set of constraints only apply to symmetric storage resources (all $y \in \mathcal{VS}^{sym,dc} \cup y \in \mathcal{VS}^{sym,ac}$). - For storage technologies with symmetric charge and discharge capacity (all $y \in \mathcal{VS}^{sym,dc} \cup y \in \mathcal{VS}^{sym,ac}$), - since storage resources generally represent a 'cluster' of multiple similar storage devices of the same type/cost in the same zone, GenX - permits storage resources to simultaneously charge and discharge (as some units could be charging while others discharge). The - simultaneous sum of DC and AC charge, $\Pi^{dc}_{y,z,t}, \Pi^{ac}_{y,z,t}$, and discharge, $\Theta^{dc}_{y,z,t}, \Theta^{ac}_{y,z,t}$, is limited - by the total installed energy capacity, $\Delta^{total, energy}_{o,z}$, multiplied by the power to energy ratio, $\mu_{y,z}^{dc,stor}, - \mu_{y,z}^{ac,stor}$. Without any capacity reserve margin constraints or operating reserves, the symmetric AC and DC storage resources are constrained as: -```math -\begin{aligned} - & \Theta^{dc}_{y,z,t} + \Pi^{dc}_{y,z,t} \leq \mu^{dc,stor}_{y,z} \times \Delta^{total,energy}_{y,z} \quad \forall y \in \mathcal{VS}^{sym,dc}, z \in \mathcal{Z}, t \in \mathcal{T} \\ - & \Theta^{ac}_{y,z,t} + \Pi^{ac}_{y,z,t} \leq \mu^{ac,stor}_{y,z} \times \Delta^{total,energy}_{y,z} \quad \forall y \in \mathcal{VS}^{sym,ac}, z \in \mathcal{Z}, t \in \mathcal{T} -\end{aligned} -``` - -Symmetric storage resources with only capacity reserve margin constraints follow a similar constraint that incorporates the 'virtual' discharging - and charging that occurs and limits the simultaneously charging, discharging, virtual charging, and virtual discharging of the battery resource: -```math -\begin{aligned} - & \Theta^{dc}_{y,z,t} + \Theta^{CRM,dc}_{y,z,t} + \Pi^{dc}_{y,z,t} + \Pi^{CRM,dc}_{y,z,t} \\ - & \leq \mu^{dc,stor}_{y,z} \times \Delta^{total,energy}_{y,z} \quad \forall y \in \mathcal{VS}^{sym,dc}, z \in \mathcal{Z}, t \in \mathcal{T} \\ - & \Theta^{ac}_{y,z,t} + \Theta^{CRM,ac}_{y,z,t} + \Pi^{ac}_{y,z,t} + \Pi^{CRM,ac}_{y,z,t} \\ - & \leq \mu^{ac,stor}_{y,z} \times \Delta^{total,energy}_{y,z} \quad \forall y \in \mathcal{VS}^{sym,ac}, z \in \mathcal{Z}, t \in \mathcal{T} -\end{aligned} -``` +with periodic wrap for start timesteps, upper bounds by `eTotalCap_STOR`, and +power-rate expressions used by symmetric/asymmetric storage limits in `vre_stor!`. -Symmetric storage resources only subject to operating reserves have additional variables to represent contributions of frequency regulation and upwards operating reserves while the storage is charging DC or AC - ($f^{dc,cha}_{y,z,t}, f^{ac,cha}_{y,z,t}$) and discharging DC or AC ($f^{dc,dis}_{y,z,t}, f^{ac,dis}_{y,z,t}, r^{dc,dis}_{y,z,t}, r^{ac,dis}_{y,z,t}$).

This ensures - that the storage device cannot use state of charge that would not have been available had it been called on to actually contribute its - pledged virtual discharge at some earlier timestep. This relationship is described by the following constraint (as also outlined in - the storage module): -```math -\begin{aligned} - & \Gamma_{y,z,t} \geq \Gamma^{CRM}_{y,z,t} \quad \forall y \in \mathcal{VS}^{stor}, z \in \mathcal{Z}, t \in \mathcal{T} \\ -\end{aligned} -``` -The overall contribution of the co-located VRE and storage resources to the system's capacity reserve margin in timestep $t$ is equal to - (including both actual and virtual DC and AC charge and discharge): -```math -\begin{aligned} - & \sum_{y \in \mathcal{VS}^{pv}} (\epsilon_{y,z,p}^{CRM} \times \eta^{inverter}_{y,z} \times \rho^{max,pv}_{y,z,t} \times \Delta^{total,pv}_{y,z}) \\ - & + \sum_{y \in \mathcal{VS}^{wind}} (\epsilon_{y,z,p}^{CRM} \times \rho^{max,wind}_{y,z,t} \times \Delta^{total,wind}_{y,z}) \\ - & + \sum_{y \in \mathcal{VS}^{sym,dc} \cup \mathcal{VS}^{asym,dc,dis}} (\epsilon_{y,z,p}^{CRM} \times \eta^{inverter}_{y,z} \times (\Theta^{dc}_{y,z,t} + \Theta^{CRM,dc}_{y,z,t})) \\ - & + \sum_{y \in \mathcal{VS}^{sym,ac} \cup \mathcal{VS}^{asym,ac,dis}} (\epsilon_{y,z,p}^{CRM} \times (\Theta^{ac}_{y,z,t} + \Theta^{CRM,ac}_{y,z,t})) \\ - & - \sum_{y \in \mathcal{VS}^{sym,dc} \cup \mathcal{VS}^{asym,dc,cha}} (\epsilon_{y,z,p}^{CRM} \times \frac{\Pi^{dc}_{y,z,t} + \Pi^{CRM,dc}_{y,z,t}}{\eta^{inverter}_{y,z}}) \\ - & - \sum_{y \in \mathcal{VS}^{sym,dc} \cup \mathcal{VS}^{asym,dc,cha}} (\epsilon_{y,z,p}^{CRM} \times (\Pi^{ac}_{y,z,t} + \Pi^{CRM,ac}_{y,z,t})) -\end{aligned} -``` +Capacity-reserve-margin coupling for VRE-STOR operations. -If long duration energy storage resources exist, a separate but similar set of variables and constraints is used to track the evolution of energy held - in reserves across representative periods, which is elaborated upon in the [`long_duration_storage!()`](@ref) function. - The main linking constraint follows (due to the capabilities of virtual DC and AC discharging and charging): +Creates virtual CRM charge/discharge variables (`vCAPRES_*`) and reserve SOC +(`vCAPRES_VS_VRE_STOR`), enforces virtual SOC dynamics, and couples reserve SOC as a +lower bound on operational SOC. -```math -\begin{aligned} - & \Gamma^{CRM}_{y,z,(m-1)\times \tau^{period}+1} = \left(1-\eta_{y,z}^{loss}\right)\times \left(\Gamma^{CRM}_{y,z,m\times \tau^{period}} -\Delta Q_{y,z,m}\right) \\ - & + \frac{\Theta^{CRM,dc}_{y,z,(m-1)\times \tau^{period}+1}}{\eta_{y,z}^{discharge,dc}} + \frac{\Theta^{CRM,ac}_{y,z,(m-1)\times \tau^{period}+1}}{\eta_{y,z}^{discharge,ac}} \\ - & - \eta_{y,z}^{charge,dc} \times \Pi^{CRM,dc}_{y,z,(m-1)\times \tau^{period}+1} - \eta_{y,z}^{charge,ac} \times \Pi^{CRM,ac}_{y,z,(m-1)\times \tau^{period}+1} \\ - & \forall y \in \mathcal{VS}^{LDES}, z \in \mathcal{Z}, m \in \mathcal{M} -\end{aligned} -``` +Adds CRM terms into module expressions (`eGridExport`, `eInverterExport`, +`eSolarGenMaxS`, `eWindGenMaxW`, storage rate expressions) and contributes CRM capacity +terms to `eCapResMarBalance`. -All other constraints are identical to those used to track the actual state of charge, except with the new variables for the representation of 'virtual' - state of charge, build up storage inventory and state of charge at the beginning of each period. +When `StorageVirtualDischarge == 1`, it adds virtual charge/discharge penalty terms to +`eObj`.

[Semantic Versioning](https://semver.org/spec/v2.0.0 ## Unreleased ### Added -- A generalized hourly matching policy module (#855). +- Added `MacroEnergySolvers` (v0.2) as a package dependency, providing shared solver infrastructure used by the Benders decomposition framework. +- Added `Gurobi` as a weak dependency with a `GenXGurobiExt` package extension, making Gurobi support optional and loaded only when the `Gurobi` package is available in the environment. +- Core Benders decomposition framework in new `src/benders/` directory: `benders_planning_problem.jl` (master problem / investment stage), `benders_subproblems.jl` (operational subproblems per representative period), `benders_utility.jl` (shared cut/convergence/logging utilities), and `results.jl` (result aggregation from subproblems). Includes `src/configure_solver/configure_benders.jl` for solver configuration. +- VRE-STOR capacity investment support for Benders decomposition via new `src/model/resources/vre_stor/investment_vre_stor.jl`, adding investment decisions and linking constraints for co-located VRE+storage resources in the master problem. +- Benders-specific policy modules for CO2 cap (`co2_cap.jl`), energy share requirement (`energy_share_requirement.jl`), and hydrogen demand (`hydrogen_demand.jl`), ensuring dual prices from each subproblem feed back into optimality cuts. +- Benders-specific resource modules for hydro inter-period linkage (`hydro_inter_period_linkage.jl`) and long-duration storage (`long_duration_storage.jl`), supporting state-of-charge linking across representative periods in the subproblems. +- Benders decomposition documentation: user guide at `docs/src/User_Guide/benders_decomposition.md` and mathematical overview at `docs/src/Model_Concept_Overview/benders_math_overview.md`; updated `docs/make.jl`, `examples_casestudies.md`, `model_configuration.md`, and `developer_guide.md` to cover Benders usage and code structure. +- Benders test suite: `test/test_benders_vs_monolithic.jl` validates that Benders and monolithic solves produce consistent objective values across example systems. +- Added `Run_benders.jl` entry point scripts to example systems 1–5, 7, 10, and 11, enabling Benders decomposition runs for each of those cases. +- A generalized hourly matching policy module. +- Benders decomposition output now writes additional files matching the monolithic solver: `prices.csv`, `reliability.csv`, `storagebal_duals.csv`, `capacityfactor.csv`, `time_weights.csv`, `EnergyRevenue.csv`, `ChargingCost.csv`, `commit.csv`, `start.csv`, `shutdown.csv` (when UCommit≥1), `CO2_prices_and_penalties.csv` (when CO2Cap>0), and `SubsidyRevenue.csv`/`RegSubsidyRevenue.csv` (when MinCap/MinCapReq is active). + +### Changed +- `capacity_decisions.jl` refactored to support both monolithic and Benders decomposition modes, cleanly separating capacity (master problem) and operational (subproblem) variables. +- `generate_model.jl` updated to route model construction through Benders subproblem or monolithic paths based on the `BendersDecomposition` settings flag. ### Fixed +- Corrected investment and operational constraints in `allamcyclelox.jl` that caused incorrect capacity accounting for the Allam Cycle with LOX storage resource type. +- Fixed effective capacity calculation in the capacity reserve margin subproblem for co-located VRE+storage resources with long-duration storage. - Fix writing of net revenue to include all sources of revenue, not just energy revenue (#855). ## [0.4.6] - 2026-01-06 diff --git a/example_systems/10_IEEE_9_bus_DC_OPF/Run_benders.jl b/example_systems/10_IEEE_9_bus_DC_OPF/Run_benders.jl index c6b682af64..936a4dfa08 100644 --- a/example_systems/10_IEEE_9_bus_DC_OPF/Run_benders.jl +++ b/example_systems/10_IEEE_9_bus_DC_OPF/Run_benders.jl @@ -1,11 +1,19 @@ ############################################################################### -# Run Example 10 (IEEE 9-bus DC OPF) using Benders decomposition with Gurobi. +# Run Example 10 (IEEE 9-bus DC OPF) using Benders decomposition. +# Uses Gurobi if available, otherwise falls back to HiGHS. ############################################################################### -using Revise -using Gurobi using GenX +const _OPTIMIZER = try + using Gurobi + Gurobi.Optimizer +catch + @warn "Gurobi is not available; using HiGHS instead." + using HiGHS + HiGHS.Optimizer +end + const _CASE = dirname(@__FILE__) const _SETTINGS_DIR = joinpath(_CASE, "settings") const _MAIN_SETTINGS = joinpath(_SETTINGS_DIR, "genx_settings.yml") @@ -16,7 +24,7 @@ cp(_MAIN_SETTINGS, _BACKUP; force = true) cp(_BENDERS_SETTINGS, _MAIN_SETTINGS; force = true) try - run_genx_case!(_CASE, Gurobi.Optimizer) + run_genx_case!(_CASE, _OPTIMIZER) catch e @error "Error running GenX case" exception = e rethrow() diff --git a/example_systems/10_IEEE_9_bus_DC_OPF/settings/highs_benders_planning_settings.yml b/example_systems/10_IEEE_9_bus_DC_OPF/settings/highs_benders_planning_settings.yml new file mode 100644 index 0000000000..cb23170791 --- /dev/null +++ b/example_systems/10_IEEE_9_bus_DC_OPF/settings/highs_benders_planning_settings.yml @@ -0,0 +1,16 @@ +# HiGHS settings for the Benders *planning* (master) problem. +# +# The master problem is a continuous LP when IntegerInvestment: false (the +# default).

The mathematical formulation for the capacity expansion model and how it is decomposed is shown in more detail in the [Benders Decomposition Overview](@ref). Benders decomposition can be especially useful when the problem can be decomposed with several independent subproblems. This is because the subproblems can each be solved in parallel after the master problem solve is complete. GenX exploits this ability by decomposing the problem in time and solving with representative time periods, such that the linking between time periods is only captured inside the master problem. This allows for each representative period to be solved independently in parallel during a single iteration of Benders. For this reason, it is generally advised that the user provide their data as representative periods or to use the time domain reduction capability of GenX, which automatically creates the representative periods for use in Benders. diff --git a/example_systems/3_three_zones_w_co2_capture/settings/genx_benders_settings.yml b/example_systems/3_three_zones_w_co2_capture/settings/genx_benders_settings.yml index 383788c270..627b4ccc47 100644 --- a/example_systems/3_three_zones_w_co2_capture/settings/genx_benders_settings.yml +++ b/example_systems/3_three_zones_w_co2_capture/settings/genx_benders_settings.yml @@ -2,7 +2,7 @@ NetworkExpansion: 1 # Transmission network expansionl;

For the regularization scheme to work, the planning problem solver must use an interior point method without crossover. Stabilization is a process in Benders where the master problem can choose less extreme solutions that are on the interior of the feasible set (see [Pecci and Jenkins](https://ieeexplore.ieee.org/abstract/document/10829583)). A challenge of Benders is that, especially at early iterations, the master problem chooses solutions that result in high costs in the subproblems (e.g., at the first iteration, Benders typically chooses to build nothing in the planning level because it is trying to minimize cost without knowledge of the operations) which results in poor cuts. The stabilization scheme generally allows the master to choose solutions that are less extreme and can result in stronger cuts early on. diff --git a/src/benders/benders_subproblems.jl b/src/benders/benders_subproblems.jl index 6176dae46c..abe4aefadc 100644 --- a/src/benders/benders_subproblems.jl +++ b/src/benders/benders_subproblems.jl @@ -87,6 +87,42 @@ function init_local_subproblems!(setup::Dict,inputs_local::Vector{Dict{Any,Any}} end end +@doc raw""" + init_sequential_subproblems(setup, inputs_decomp, planning_variables, optimizer) + +Initialize all Benders subproblems as a plain `Vector{Dict}` on the current process. + +Used when `nworkers() == 1` (no extra Julia workers are available).
