Update POM for PSY MarketBidCost/ImportExportCost static/TS split by luke-kiernan · Pull Request #77 · Sienna-Platform/PowerOperationsModels.jl

luke-kiernan · 2026-04-14T17:37:10Z

Summary

PSY split MarketBidCost and ImportExportCost into separate static and time-series variants (MarketBidCost + MarketBidTimeSeriesCost, ImportExportCost + ImportExportTimeSeriesCost). This PR mirrors the IOM refactor (IOM PR #74) on the POM side and adds a unit-test suite for the MBC/IEC objective-function construction.

Depends on IOM PR #74.

Changes

Dispatch (src/)

Consolidated MBC OnVariable dispatch into a single generic pair in common_models/market_bid_overrides.jl, keyed on an _onvar_offer_direction trait (Generator → IncrementalOffer, ControllableLoad → DecrementalOffer). Per-device thermal/hydro/load overrides drop out.
Replaced stale isnothing(get_{input,output}_offer_curves(...)) checks with IOM.is_nontrivial_offer — ZERO_OFFER_CURVE is now the default, not nothing. Load dispatch rejects non-trivial supply with ArgumentError.
Delegated hydro add_proportional_cost! to IOM's shared add_proportional_cost_maybe_time_variant!, dropping a broken _lookup_maybe_time_variant_param path that never had a definition.
Collapsed is_time_variant_term to a one-arg form (output depends only on cost type).
_get_time_series_name for *CostAtMinParameter traverses through the curve — initial_input now lives inside TimeSeriesPiecewiseIncrementalCurve, not on MBC directly.

Tests

Existing MBC/IEC helpers (add_market_bid_cost.jl, mbc_system_utils.jl, iec_simulation_utils.jl) updated for LinearCurve scalar fields and the new TS cost constructors.

New unit-test suite, focused on "do the objective function terms and constraints turn out correct":

test/test_market_bid_cost.jl — Load (PowerLoadDispatch, PowerLoadInterruption) and Thermal (BasicUC, MultiStartUC) with static and TS costs. One testset per (device × formulation × cost-type); dedicated scaling testsets cover dt / unit conversion. Multi-start testset exercises per-stage start_up_cost dispatch with a Tuple-valued StartupCostParameter.
test/test_import_export_cost.jl — Source + ImportExportSourceModel with static and TS IEC, distinct import/export breakpoints (widths asserted).
test/test_utils/mbc_math_helpers.jl — minimal system builders, OptimizationContainer setup, JuMP variable seeding, objective coefficient / PWL delta coefficient / PWL delta width inspection, stub TS curve/MBC construction, parameter seeding helpers.

Flagged for follow-up

// FIXME in the Source IEC dispatch: we now always add PWL for both directions (previous isnothing guard was dead in the new PSY). A cheap TS-curve emptiness check would let us skip the unused side for a one-directional Source.

Test plan

Full POM test suite passes locally (julia --project=test -e 'include(\"test/runtests.jl\")').
New test_market_bid_cost.jl (29 tests) and test_import_export_cost.jl (13 tests) pass.
IOM test suite still passes after the coupled bug-fix commit in IOM PR Update POM to work with IOM main #74.

PSY split MarketBidCost and ImportExportCost into separate static and time-series-backed types (MarketBidCost + MarketBidTimeSeriesCost, ImportExportCost + ImportExportTimeSeriesCost). This mirrors the IOM update (PR #74) on the POM side. Dispatch changes: - Consolidate MBC OnVariable proportional_cost + is_time_variant_term into a single generic pair in market_bid_overrides.jl, keyed on an _onvar_offer_direction trait (Generator → IncrementalOffer, ControllableLoad → DecrementalOffer). Per-device thermal/hydro/load overrides drop out. - Replace stale `isnothing(get_{input,output}_offer_curves(...))` checks with IOM.is_nontrivial_offer (ZERO_OFFER_CURVE is now the default, not nothing). Load dispatch rejects non-trivial supply with ArgumentError. - Delegate hydro's add_proportional_cost! to IOM's shared add_proportional_cost_maybe_time_variant! (drops a broken _lookup_maybe_time_variant_param path). - Collapse is_time_variant_term / Type-based signatures to match IOM. - _get_time_series_name for *CostAtMinParameter traverses through the curve (initial_input now lives inside TimeSeriesPiecewiseIncrementalCurve, not on MBC directly). Test utilities rewritten for the new types. Existing MBC/IEC test helpers (add_market_bid_cost.jl, mbc_system_utils.jl, iec_simulation_utils.jl) updated to use LinearCurve fields and the new TS cost constructors.

Copilot

Pull request overview

Updates PowerOperationsModels (POM) to match PowerSystems (PSY) splitting MarketBidCost / ImportExportCost into separate static vs time-series cost types, and adds focused unit tests that assert the resulting objective-function coefficients/constraints are wired correctly.

Changes:

Refactors MBC/IEC dispatch and PWL helpers to use the new static/TS cost-type split (and new IOM delta/lambda PWL APIs).
Updates test utilities for new curve scalar-field types and introduces new unit test suites for MBC/IEC objective construction.
Adds network-model branch compatibility validation using the updated IOM compatibility check signature.

test/Project.toml:41

test/Project.toml no longer pins InfrastructureOptimizationModels in [sources] and also doesn’t constrain it in [compat]. Since the test suite now relies on the updated IOM APIs used in this PR, consider adding an explicit compat lower bound (or a source override) here as well to avoid CI / local test runs resolving an older IOM version that can’t load the code.

Upstream PSY now types `MarketBidTimeSeriesCost.start_up` as `TupleTimeSeries{StartUpStages}` instead of a bare `TimeSeriesKey`: - `_get_time_series_name(::StartupCostParameter, ...)` extracts the key via `IS.get_time_series_key` (mirrors the existing Shutdown path). - `validate_occ_component` on `ThermalMultiStart` early-returns for TupleTimeSeries — values are pre-validated to `NTuple{3, Float64}` at construction. - Renewable/Storage startup-nonzero check compares via `any(!iszero, values(x))` so it works for both static `StartUpStages` (NamedTuple) and TS-backed `NTuple{3, Float64}` elements. - Test helpers (`extend_mbc!`, `_promote_mbc_to_ts!`, `stub_ts_market_bid_cost`) wrap the TimeSeriesKey in `IS.TupleTimeSeries{PSY.StartUpStages}` when constructing `MarketBidTimeSeriesCost`.

…include New `test/test_mbc_parameter_population.jl` exercises the `system-with-TS → parameter container` half of the MBC pipeline, which was previously only covered transitively. IEC PWL is `@test_broken` pending the PSI→POM migration of slope/breakpoint overloads. Along the way: - Include `src/core/default_interface_methods.jl` from the main module so `get_multiplier_value` for OCC parameters resolves to the defaults instead of the catch-all error. - Drop the duplicate `requires_initialization` in that file (IOM already defines it; the duplicate caused a method-overwrite warning). - Add `IS.@assert_op op_cost isa TS_OFFER_CURVE_COST_TYPES` at the top of each OCC `_get_time_series_name` method so a future bypass of IOM's filter surfaces a clean precondition error.

This relies on IOM #74 but otherwise this is good to merge. Tests pass locally, ignoring one PSB-related failure.

TS types are validated at parameter population time

As far as Claude can tell, this doesn't actually happen. I'll open an issue for it and add a test.
