| # REG-Forecasting (TsFile) |
|
|
| Apache TsFile version of |
| [`wachawich/REG-Forecasting`](https://huggingface.co/datasets/wachawich/REG-Forecasting). |
|
|
| ## Overview |
|
|
| Renewable Energy Generation (REG) forecasting data at **hourly** granularity, spanning |
| **2020-01-01 to 2025-11-19** (UTC). Each record pairs the power generation of a given hour |
| (`value`) with the meteorological and solar-geometry features for that same hour, for use in |
| generation-forecasting models. |
|
|
| - **Two generation types:** `type_name` = `Solar` / `Wind` (`fueltype` 1 / 2). |
| - **Forecast target:** `value` — generation in that hour. |
| - **Features:** radiation, cloud cover, temperature, humidity, pressure, wind speed/direction, |
| precipitation, plus engineered features such as `day_of_year`, `sin_doy`, `cos_doy`, `season`, |
| `solar_zenith_noon_deg`, and sunrise/sunset times. |
|
|
| ## Schema (TsFile structure) |
|
|
| - **Time** (INT64, milliseconds, UTC) — the timestamp of each hourly record. |
| - **type_name** (TAG) — the device dimension, `Solar` / `Wind` (2 devices). Query a single |
| type with `WHERE type_name='Solar'`. |
| - All remaining columns are FIELDs: `value` plus the meteorological and engineered features. |
| |
| Type mapping: integer columns → INT64, floating-point columns → DOUBLE, string columns → STRING. |
| |
| ## Usage |
| |
| Read `data.tsfile` with the Apache TsFile Java or Python SDK. |
