# PowerZoo Dataset

Real-world power-system and data-centre time-series, canonical grid topologies, and JSON manifests linking the two — packaged for reinforcement-learning and forecasting research with the PowerZoo / PowerZooJax benchmark code (released separately).

---

## 1. What's inside

1. Eleven parquet time-series files ingested from public regulator and cloud-provider releases (GB / AU electricity load, generation by fuel, day-ahead forecasts, market mid-prices; Alibaba / Azure / Google data-centre utilisation).
2. Fourteen electrical-network case files (Python classes with bus / branch / generator / load tables) covering transmission systems from 5 to 2383 buses and distribution systems from 33 to 533 buses.
3. Eleven JSON manifests that map each parquet's raw columns to a shared canonical schema (e.g. `OPERATIONAL_DEMAND``load.actual_mw`), so traces from different sources compose cleanly in one experiment.

Each `*.parquet` ships with a sibling `*.json` capturing source URL, source organisation, generation timestamp, exact column dtypes, region/category enumerations and (where applicable) timezone conventions.

### 2.2 Manifests

Manifests in `manifests/` are the contract used by PowerZoo / PowerZooJax loaders. A manifest declares:

- `parquet_file` and the matching `metadata_json`
- `column_map`: rename rules from raw column → canonical schema (e.g. `OPERATIONAL_DEMAND → load.actual_mw`)
- `index_map`: which raw columns serve as `datetime` / `region` / `issue_time` / `target_time`
- `derived`: closed-form derivations from raw columns (e.g. `wind.available_mw = "Wind Offshore + Wind Onshore"`)
- `normalize`: per-channel scaling factors applied at load time
- `time_mode`: `calendar` (absolute UTC) or `profile` (cyclical, anchored to `data_epoch`)
- `region_values`, `date_range`, `source_url`, `source_organization`

The 11 manifests cover every parquet file shipped here. Note that `gb_neso_demand` uses a two-column index (`SETTLEMENT_DATE` + `SETTLEMENT_PERIOD` 1–50) instead of a single `datetime` column — the manifest's `datetime_recipe` field documents the exact reconstruction (Europe/London tz-localise then convert to UTC; SP=49–50 absorb the autumn clock-change repeat).

### 2.3 Power-grid case files

`powergrid_case/` contains a unified Python representation for both transmission and distribution test systems. Every case subclasses `ClearCase` and exposes four `pandas.DataFrame` tables in MATPOWER-compatible units (MW, MVAr, p.u.):

- `nodes``id, type (1=PQ / 2=PV / 3=Ref), Pd, Qd, x, y`
- `units``id, bus_id, mc_a, mc_b, mc_c, p_max, p_min` (quadratic cost + capacity)
- `lines``id, from, to, x, floor, cap` (reactance + thermal limits)
- `loads``id, bus_id, mc_a, mc_b, mc_c, d_max, d_min` (price-responsive demand)

Each file declares `BUS_COUNT`, `VOLTAGE_LEVEL`, `SOURCE` and `DESCRIPTION` as class-level metadata. The values below are reproduced verbatim from those declarations (so the file itself is the source of truth):


| File                             | Voltage | Buses | `SOURCE` | `DESCRIPTION`                                                      |

## 3. Loading

### 3.1 Direct parquet load (no extra dependency on PowerZoo)

```python
import pandas as pd
from huggingface_hub import hf_hub_download

path = hf_hub_download(
    repo_id="PowerZooJax/PowerZooDataset",
    repo_type="dataset",
    filename="parquet/AEMO_5min_Demand_2025_2026.parquet",
)
df = pd.read_parquet(path)
print(df.head())
```

### 3.2 Via `datasets` (per-config)

```python
from datasets import load_dataset

ds = load_dataset(
    "PowerZooJax/PowerZooDataset",
    name="aemo_5min_demand",
    split="train",
)
```

### 3.3 Via the PowerZooJax `DataLoader`

If you have the (separately released) benchmark package installed, instantiate `DataLoader` with this repository's `parquet/` and `manifests/` directories:

```python
from powerzoojax.data import DataLoader

loader = DataLoader(
    data_dir="/path/to/PowerZooDataset/parquet",
    manifest_dir="/path/to/PowerZooDataset/manifests",
)
print(loader.list_available_datasets())
df = loader.load_actual_series("aemo_5min_demand")
```

### 3.4 Power-grid cases

```python
from powerzoo.case.distribution.Case141 import Case141
case = Case141()
case.check()
case.get_node_ptdf()
```

---

## 4. Schema conventions

- **Time stamps.** Calendar-mode parquet files store timestamps as `datetime64[ns, UTC]`, with the exception of `GB_NESO_Demand_2009_2025_30min.parquet`, which uses two columns (`SETTLEMENT_DATE` + `SETTLEMENT_PERIOD`) — see the `datetime_recipe` in `manifests/gb_neso_demand.json`. The Ausgrid metadata explicitly declares `timezone_local = "Australia/Sydney"` and `timezone_stored = "UTC"`; for the other calendar sources, only the stored UTC representation is documented in metadata.
- **Profile-mode traces.** The data-centre traces (Alibaba / Azure / Google) are tagged `time_mode = "profile"` and `cyclical = true` in their manifests, anchored to a `data_epoch` (Alibaba DC: `2018-01-06`, Alibaba GPU: `2020-07-01`, Azure: `2019-01-01`, Google: `2019-05-01`). They are intended as periodic exogenous signals, not absolute calendar series.
- **Imputation.** `Ausgrid_Zone_Substation_FY25_imputed_15min.parquet` contains imputed values (as indicated by its filename suffix and source path); the imputation method is not documented inside the metadata shipped here. Users requiring raw observations should pull from the upstream Ausgrid release.
- **Units.** Power columns in the parquet traces are in MW. The GB market-mid file uses prices in `mid_price_`* columns (the upstream Elexon convention is £/MWh; consult the source URL for any unit caveats). Data-centre utilisation columns are 0–100 (percent) before the manifest's `normalize` factor is applied.

## 5. Source acknowledgements & licensing

This repository **redistributes derivative datasets** built from publicly accessible upstream releases. Each upstream is governed by its own terms; users are responsible for complying with them. The `source_url` and `source_organization` fields in every `parquet/*.json` and `manifests/*.json` give the canonical pointer.

The packaging artefacts authored for this benchmark (the manifest schema, case-file Python representations, schema harmonisation logic) are intended to be released under a permissive open-source licence at camera-ready time; the underlying parquet data inherits the upstream licence in every case. The canonical copy is the upstream URL above.

All series are aggregated at substation, regional, or national level; no PII.

## 6. Intended use & limitations

**Intended use.** Reinforcement-learning research, load / generation forecasting, OPF benchmarking, distribution-system control, data-centre power-shaping, demand-response studies.

**Limitations.**
- Static snapshot at release time; upstream sources continue to publish. Redownload from the URLs in §5 for live data.
- Geographic scope: Great Britain and Australia only.
- The Ausgrid trace is imputed by the upstream publisher; the imputation procedure is not documented here.
- Data-centre traces ship only the columns each manifest maps, at 5-minute resolution; upstream releases offer more fields at finer cadences.
- Grid-case parameter values are consistent with the named source systems but are not byte-identical to any specific upstream release.

Not intended for real-time grid control, retail tariff design, or settlement of real markets.

## 7. File integrity

To regenerate provenance metadata locally:

```bash
python -c "
import pyarrow.parquet as pq, glob, os
for p in sorted(glob.glob('parquet/*.parquet')):
    m = pq.read_metadata(p)
    print(f'{os.path.basename(p):60s}  rows={m.num_rows:>10,}  cols={m.num_columns:>3}  bytes={os.path.getsize(p):>10,}')
"
```

Expected output is reproduced in §2.1.
