European Power Grid Frequency Time Series

Pre-processed frequency recordings from three synchronous areas of the European power grid: Continental Europe, Great Britain, and the Nordic region. The data is cleaned and converted into ready-to-use time series, accompanied by Python scripts for downloading and processing raw data from Transmission System Operators. This dataset supports research on grid stability, frequency prediction, and the integration of renewable energy sources.

Use Cases

• Forecasting power grid frequency based on historical time series data
• Analyzing grid stability and disturbance events across different European regions
• Benchmarking time series anomaly detection algorithms on real-world sensor data
• Studying the impact of renewable energy integration on grid frequency variations

Strengths

• Includes data from three distinct European power grid regions, enabling comparative analysis
• Provides both raw download scripts and pre-processed, cleansed data with missing values marked as NaN
• Associated with a peer-reviewed paper ('Predictability of Power Grid Frequency'), indicating research validation

Limitations

• Key metadata such as row count, specific time range, and exact column structure is unknown from the provided sources
• License terms are complex and vary by source region (e.g., re-publication requires request for Continental Europe data)
• Documentation for the pre-processing procedure is referenced but not directly provided in the descriptions

Provenance

Source

Frequency recordings downloaded from public repositories of three Transmission System Operators (TSOs): TransnetBW GmbH (Continental Europe), National Grid ESO (Great Britain), and Fingrid (Nordic).

Collection Method

Data was downloaded using provided Python scripts, converted to correct timestamp formats, and cleansed to mark corrupted recordings as NaN.

Geography

Covers three synchronous areas of the European power grid: Continental Europe, Great Britain, and the Nordic region.
