Retained Artifacts

After repo cleanup, this Maryland benchmark is intentionally documented around only the artifacts that should remain part of the long-term repo surface:

source GTEP case: ModelCases/MD_GTEP_holistic_full8760_case_v20260406g
source PCM case: ModelCases/MD_PCM_holistic_full8760_case_v20260406g
preserved reference GTEP run: ModelCases/MD_GTEP_holistic_full8760_case_v20260406g_gtep_run_20260406_210316_674
preserved reference PCM run: ModelCases/MD_PCM_holistic_full8760_case_v20260406g_pcm_run_20260406_210316_734

Older intermediate Maryland holistic variants were exploratory build/debug artifacts and are not part of the benchmark definition.

Current Build Summary

This is the canonical small full-function Maryland holistic benchmark for HOPE.

The benchmark uses a shared Maryland-only four-zone baseline for both stages, runs the full 8760-hour chronology, and exercises the full direct run_hope_holistic(...) handoff from GTEP investment decisions into PCM operations.

The final v20260406g pair is the first Maryland full-year holistic benchmark in this repo that is both structurally correct and operationally healthy:

the GTEP and PCM stages start from the same Maryland-only baseline
the load file preserves the original NI net-import semantics used by HOPE
the holistic handoff persists the updated PCM input files before the PCM solve
the preserved reference solve completes end to end with zero annual load shedding in both stages

Review Focus

This page is meant to support review of four specific claims:

the benchmark is a true shared-baseline GTEP-to-PCM pair rather than two loosely related MD cases
the Maryland-only reduction kept the intended topology, load, and policy semantics
the holistic handoff is reflected not only in-memory but also in the persisted PCM case inputs
the preserved successful pair is stable enough to use as the repo's main small full-function holistic regression benchmark

Holistic Handoff Check

This benchmark is also the reference case for verifying that the GTEP-to-PCM transfer is persisted correctly.

The preserved PCM output_holistic/resource_aggregation_summary.csv explicitly contains the handed-off build groups G29 through G36, matching the eight new VRE build rows from the GTEP stage:

Aggregated resource	Zone	Type	Original Pmax (MW)
`G29`	`APS_MD`	`WindOn`	1315.931
`G30`	`APS_MD`	`SolarPV`	1579.117
`G31`	`DPL_MD`	`WindOn`	1096.686
`G32`	`DPL_MD`	`SolarPV`	1423.228
`G33`	`BGE`	`WindOn`	3671.260
`G34`	`BGE`	`SolarPV`	351.256
`G35`	`PEPCO`	`WindOn`	2238.523
`G36`	`PEPCO`	`SolarPV`	1705.376

That makes this pair the repo's main regression benchmark for:

shared-baseline holistic execution
Maryland-only topology correctness
NI-preserving load semantics
PCM input persistence after GTEP handoff
zero-load-shedding end-to-end validation

Reproduction

The benchmark can be rerun from the retained source pair through the library entry point that creates fresh case clones before solving:

using HOPE

result = HOPE.run_hope_holistic_fresh(
    "ModelCases/MD_GTEP_holistic_full8760_case_v20260406g",
    "ModelCases/MD_PCM_holistic_full8760_case_v20260406g",
)

That workflow is preferred over case-specific runner scripts because it keeps the reusable orchestration in src/run_holistic.jl and avoids reusing stale output/ trees.
