From 0bf1ff5df4384847b39f0e720e9d081b1b6773b1 Mon Sep 17 00:00:00 2001 From: Anthony Costarelli Date: Wed, 29 Apr 2026 09:32:25 -0600 Subject: [PATCH 01/46] Bilinear hydro formulation and IOM/PSY API updates MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the bilinear (flow*head) hydro dispatch formulation and folds in adjacent refactors merged through this branch: - Hydro and storage updates to IOM helpers (#97) - POM-to-IOM type-dispatch API migration - MarketBidCost / ImportExportCost static/TS split + IEC refactor - Shiftable-load interval indexing and validation fixes - HDF system serialization (#75) - Pin GitHub revisions; bridge IOM system-query stubs to PSY public API Co-Authored-By: Luke Kiernan <86331877+luke-kiernan@users.noreply.github.com> Co-Authored-By: Rodrigo Henríquez-Auba Co-Authored-By: Jose Daniel Lara Co-Authored-By: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> --- Project.toml | 5 + ext/PowerFlowsExt/PowerFlowsExt.jl | 2 +- src/PowerOperationsModels.jl | 25 +- src/common_models/add_parameters.jl | 53 +- src/common_models/market_bid_overrides.jl | 117 +++- src/common_models/market_bid_plumbing.jl | 621 ++++++++++++++++++ src/core/constraints.jl | 53 ++ src/core/default_interface_methods.jl | 5 +- src/core/expressions.jl | 3 + src/core/formulations.jl | 15 +- src/core/parameters.jl | 12 + src/core/variables.jl | 16 + .../storage_constructor.jl | 4 +- src/energy_storage_models/storage_models.jl | 412 ++++-------- .../update_initial_conditions.jl | 1 + src/network_models/pm_translator.jl | 17 + src/operation/decision_model.jl | 10 + src/operation/emulation_model.jl | 10 + src/operation/template_validation.jl | 4 +- src/static_injector_models/electric_loads.jl | 387 ++++++++++- .../hydro_generation.jl | 550 +++++----------- .../hydrogeneration_constructor.jl | 34 +- .../load_constructor.jl | 220 +++++++ .../thermal_generation.jl | 164 +++-- .../TwoTerminalDC_branches.jl | 24 + test/Project.toml | 6 + test/includes.jl | 1 + test/test_device_hydro_constructors.jl | 178 +++++ test/test_device_load_constructors.jl | 114 +++- test/test_import_export_cost.jl | 165 +++++ test/test_is_time_variant_proportional.jl | 94 +++ test/test_market_bid_cost.jl | 341 ++++++++++ test/test_mbc_parameter_population.jl | 307 +++++++++ test/test_utils/add_market_bid_cost.jl | 57 +- test/test_utils/iec_simulation_utils.jl | 38 +- test/test_utils/mbc_math_helpers.jl | 485 ++++++++++++++ test/test_utils/mbc_system_utils.jl | 184 +++--- test/test_utils/model_checks.jl | 2 +- 38 files changed, 3784 insertions(+), 952 deletions(-) create mode 100644 src/common_models/market_bid_plumbing.jl create mode 100644 test/test_import_export_cost.jl create mode 100644 test/test_is_time_variant_proportional.jl create mode 100644 test/test_market_bid_cost.jl create mode 100644 test/test_mbc_parameter_population.jl create mode 100644 test/test_utils/mbc_math_helpers.jl diff --git a/Project.toml b/Project.toml index ae4e89b..e749a78 100644 --- a/Project.toml +++ b/Project.toml @@ -26,6 +26,11 @@ PowerFlows = "94fada2c-0ca5-4b90-a1fb-4bc5b59ccfc7" [extensions] PowerFlowsExt = "PowerFlows" +[sources] +InfrastructureSystems = {url = "https://github.com/NREL-Sienna/InfrastructureSystems.jl", rev = "IS4"} +PowerSystems = {url = "https://github.com/NREL-Sienna/PowerSystems.jl", rev = "psy6"} +InfrastructureOptimizationModels = {url = "https://github.com/NREL-Sienna/InfrastructureOptimizationModels.jl", rev = "lk/pom-test-fixes"} + [compat] Dates = "1" DocStringExtensions = "~0.8, ~0.9" diff --git a/ext/PowerFlowsExt/PowerFlowsExt.jl b/ext/PowerFlowsExt/PowerFlowsExt.jl index 132e85e..9401806 100644 --- a/ext/PowerFlowsExt/PowerFlowsExt.jl +++ b/ext/PowerFlowsExt/PowerFlowsExt.jl @@ -2,7 +2,7 @@ module PowerFlowsExt using InfrastructureOptimizationModels using PowerFlows -import InfrastructureOptimizationModels: IS, PNM, PSY +import InfrastructureOptimizationModels: IS import InfrastructureOptimizationModels: OptimizationContainerKey, AbstractPowerFlowEvaluationData diff --git a/src/PowerOperationsModels.jl b/src/PowerOperationsModels.jl index 5a7967e..bd68bcb 100644 --- a/src/PowerOperationsModels.jl +++ b/src/PowerOperationsModels.jl @@ -107,10 +107,12 @@ import InfrastructureOptimizationModels: get_default_time_series_names, # proportional cost proportional_cost, -

Mechanism: - Define `get_min_max_limits(::PSY.HybridSystem, ::ActivePowerVariableLimitsConstraint, ::AbstractHybridFormulation)` to read `PSY.get_active_power_limits(PSY.get_thermal_unit(d))`. IOM's helper picks up `OnVariable` keyed by `PSY.HybridSystem` automatically. - For the with-reserves case, introduce two expression types subtyping `RangeConstraint{UB,LB}Expressions`: `HybridThermalActivePowerWithReserve{UB,LB}`. Argument-stage `add_expressions!` aggregates `p_th + Σ r_up` (UB) and `p_th − Σ r_dn` (LB) into them, after which IOM's expression-typed dispatch emits `min·on ≤ p_th − r_dn` and `p_th + r_up ≤ max·on` directly. Removes: - HybridThermalOnVariableUbConstraint, HybridThermalOnVariableLbConstraint, HybridThermalReserveLimitConstraint (constraint types + exports) - _thermal_reserve_up_expr / _thermal_reserve_down_expr helpers - Three add_constraints! bodies (~190 lines) Renewable cases stay hand-written for now: IOM's parameterized helper filters by `IS.has_time_series(d, ts_type, ts_name)`, and PSY's HybridSystem doesn't expose its inner RenewableDispatch's time series through that accessor. A separate change would be required. Verified: 50/50 hybrid tests pass.

Add a method to handle this, or restructure existing dispatch." Eliminates every `isa(service, PSY.Reserve{...})` and `service isa skip_kind` site in hybrid_systems.jl. The `_excluded_reserve_kind` trait stub goes away — its information is now encoded by union types in helper method signatures. Five sites refactored, all sharing the same shape (per-direction no-op methods + a fallback `::PSY.Service` work method): - `add_to_expression!` for HybridTotalReserveExpression / HybridServedReserveExpression → `_accumulate_reserve!` - `add_to_expression!` for the eight Reserve*Balance{Up,Down} {Charge,Discharge} expressions → `_balance_term!` plus a `_deployment_factor` per-T trait that replaces the `is_up`/`is_deployment` Booleans - `_renewable_reserve_up/down_expr` → `_renewable_reserve_*_term!` thunks sharing `_accumulate_renewable_reserve!` - `_thermal_reserve_up/down_expr` → analogous restructure - `add_constraints!` for ReserveCoverageConstraint{,EndOfPeriod} → `_init_coverage_container!` + `_emit_coverage_constraint!`; the `(service isa PSY.Reserve) || continue` guard becomes the `::PSY.Service` fallback no-op Helper arguments use concrete types (OptimizationContainer, String, Int, Float64, PSY.Storage, …) plus parametric `::Type{T}`/`::Type{U}`/ `d::V`/`::W` to reduce precompilation overhead. - "Combine these if statements." Merges the two adjacent setup ternaries (`r_ub, r_lb = if has_reserves …` and `con_lb = if has_reserves …`) in `add_constraints!(::Type{HybridStatus{Out,In}OnConstraint}, …)` into a single 3-tuple ternary. Test.detect_ambiguities returns 0; full suite passes (50/50).

Assignment/Deployment), and UB/LB singleton structs plus ~14 paired trait helpers that all differed only by which sibling they referenced. Introduce marker singletons for ReserveSide, ReserveDirection, ReserveScale (UnscaledReserve / DeployedReserve), reuse IOM's BoundDirection (UpperBound/LowerBound), and reparametrize the family roots: - ReserveAggregationExpression{D,S,Sd} umbrella with two concrete struct families (HybridPCCReserveExpression, StorageReserveBalanceExpression) covering all 16 historical reserve-expression singletons. - HybridPCCReserveVariable{Sd}, HybridStorageSubcomponentReserveVariable{Sd}, HybridStorageSubcomponentPower{Sd}, RegularizationVariable{Sd}. - HybridStatusOnConstraint{Sd}, HybridStorageStatusOnConstraint{Sd}, HybridStorageReservePowerLimitConstraint{Sd}, RegularizationConstraint{Sd}, HybridThermalOnVariableConstraint{B}. All 34 historical concrete names are retained as const aliases so external imports, `get_expression`/`get_variable`/`get_constraint` lookups, and module exports are byte-compatible. Inside hybrid_systems.jl this lets: - _accumulate_reserve! + _balance_term! collapse into one _add_reserve_term! family (PCC boundary and storage subcomponent share the no-op skip and scale dispatch); - thermal/renewable subcomponent accumulators (10 helpers) collapse into one _subcomponent_reserve_term! / _subcomponent_reserve_expr family parametric on the variable type; - the UB/LB thermal-on-variable add_constraints! methods merge; - ~14 paired trait helpers (storage / PCC / regularization) become parametric single-method definitions; - 5 file-local Union consts (_BalanceUpExpr, _BalanceDownExpr, _BalanceDeploymentExpr, _HybridReserveUpExpr, _HybridReserveDownExpr) and _StorageCharge/DischargeSide Union consts get deleted. Additional cleanups: - get_variable_multiplier hybrid signatures take ::Type{<:Formulation} (matches the rest of POM); all W() instance call-sites become type-keyed. - Three `if W <: ...` body-level subtype checks split into separate parametric dispatched methods (HybridStorageBalanceConstraint, RegularizationConstraint, HybridStatusOnConstraint). - _init_coverage_container! uses lazy_container_addition! (idempotent). - add_proportional_cost!(OnVariable, hybrids) hoists the variant/invariant function-handle selection out of the per-t loop. Net: -142 lines across 5 files.

"bilinear_approximation" ("bin2" | "hybs" | "nmdt" | "dnmdt" | "none") - "bilinear_quadratic_method" ("solver_sos2" | "manual_sos2" | "sawtooth"; "bin2" also accepts "nmdt" | "dnmdt") - "bilinear_tolerance" (finite, > 0) Unlike the original attribute era there is no bilinear_epigraph_depth attribute: every discretization depth (inner quad, HybS's internal epigraph, NMDT/DNMDT) is derived from the tolerance and the per-device flow/head ranges via IOM's tolerance_depth / tolerance_epigraph_depth helpers. bilinear_add_mccormick stays dropped (defers to IOM defaults, TODO retained). core/bilinear_configs.jl is now the string -> IOM-config bridge (_build_bilinear_config), with per-scheme quad validation and tolerance validation at constraint-build time. Adds a testset covering the bridge's happy paths and error paths.

charset=UTF-8 Content-Transfer-Encoding: 8bit The single absolute bilinear_tolerance was an absolute gap on the v·I / flow·head product, whose magnitude differs by formulation, so the same 1e-2 was far stricter for converters (depth 15, intractable) than for hydro. Replace it across all bilinear formulations (HydroTurbineMILPBilinearDispatch, QuadraticLossConverterMILP, HVDCTwoTerminalVSCLP) with two keys: bilinear_relative_tolerance (default 0.05, a fraction of the product magnitude and the default sizing knob) and bilinear_absolute_tolerance (optional). A relative tolerance is scaled to absolute by the term magnitude via the new _resolve_tolerance / _max_abs helpers (max|x|·max|y| for the bilinear, max|i|² for the standalone I² loss term); when both are set the finer binds. The gap→depth inversion stays in IOM; POM does the relative→absolute scaling since it needs the bounds. Default depth drops from 15 to 5 on the converter test systems.

The assertion passed vacuously and the accompanying comment rationalized it incorrectly. - Replace it with a conservativeness bound (milp_obj <= nlp_obj * 1.06): the bin2 McCormick relaxation lower-bounds the NLP, allowing for the 5% MIP gap. Use horizon=3h + mip_rel_gap=0.05 so the SOS2 model solves in ~1s instead of timing out. Add a TODO documenting why forced flow is currently unbuildable (DCPPowerModel + VoltageDispatchHVDCNetworkModel fails: QuadraticLossConverter wires into ActivePowerBalance__DCBus, which only the copperplate path creates). - Strengthen the VSC test (genuine forced flow: the VSC replaces a line) to assert the solutions agree, not just objectives: both models push the VSC past 1.5 pu and aggregate throughput agrees within rtol 0.1.

The subcomponent feed stays gated on storage. Adds a regression test. - C7: give the hybrid end-of-period energy target its own HybridEnergyTargetConstraint (a one-sided floor e_T >= E_T, no slacks) instead of reusing the storage StateofChargeTargetConstraint (an equality with surplus/shortfall slacks), and fix the hybrid formulation docstring to match.

Mirror POM's storage StateofChargeTargetConstraint, adapted for the hybrid: - Add HybridEnergySurplusVariable / HybridEnergyShortageVariable (non-negative, final-time-step only) and export them. - Make HybridEnergyTargetConstraint a soft equality e_T - e+ + e- = E_T. - Penalize both slacks in the objective from the storage subcomponent's StorageCost (energy_surplus_cost / energy_shortage_cost), gated on energy_target. - Add the slacks in the constructor ArgumentConstructStage. - Broaden the slack add_variables! and the target add_constraints! to accept Vector as well as FlattenIteratorWrapper. Keep the existing target RHS scaling (storage_target is a ratio of capacity in PSY; the hybrid EnergyVariable is absolute energy), which is the one intentional divergence from HSS's raw get_storage_target. Add tests modeled on the storage energy-target tests: assert the slacks exist and the constraint is an equality (would have caught the regression), that the slacks are absent when energy_target=false, and an on-vs-off objective check confirming the penalty reaches the objective.
