Database of Power Grid Frequency Measurements
arXiv:2006.01771
Abstract
The transformation of the electrical energy system attracts much attention in diverse research communities. Novel approaches for modeling, control, and power grid architectures are widely proposed. Data from actual power system operation are therefore critical to evaluate models and to analyze real-world scenarios. However, they are rarely available. In the present paper, we introduce a precisely time-stamped data set of power grid frequency measurements. It covers twelve synchronous areas of different sizes in one-second resolution. The contribution includes synchronized measurements within the Continental European synchronous area acquired in Portugal, Germany, and Turkey, maximizing the geographical span. Finally, we provide excerpts of the underlying waveform. Data were collected using a self-developed measurement instrument, the Electrical Data Recorder (EDR), connected mostly to conventional power sockets. We close our description with a discussion on measurement error and data quality.
