Site-2-FR-Distribution grid frequency data.

Data Specifics:The provided data encompasses real-time series of micro-synchrophasor frequency information gathered through an innovative device at solar sites situated in England, United Kingdom. Within each site's directory, there exists data for the duration of April 2023. Within the monthly folder, there are daily files holding timestamps and grid frequencies for entire days. These daily files contain data points at 10ms intervals, resulting in a total of 8.64 million frequency data points to depict the daily grid frequency patterns.The files are stored in the parquet format, designed in a columnar data structure, rendering them well-suited for large-scale data analysis. Accessing the data is possible using Python, MATLAB, or any other appropriate environment. Instructions and code for reading the data using MATLAB and Python can be found in the associated GitHub repository linked to the Figshare project.
