Updated: . Based on 30 seconds aggregation (PRC activation)
Grid-Time corrections may cause base frequency to be lifted by +/- 10 Mhz
Grid ability to recover from a low/high frequency. Peaks indicate an incident that got balanced by regulation energy.

Observation Incident Size for System Response Analysis. Large incidents, such as the sudden loss of generation or load, that exceed 600 MW (first level) respectively 1000 MW (second level) in the SYNCHRONOUS AREA, trigger a response analysis procedure. .
For FREQUENCY CONTROL, the quasi steady-state security margin is defined to be 20 mHz
The maximum dynamic FREQUENCY DEVIATION of ±800 mHz includes a safety margin. This margin of 200 mHz in total is intended to cover the following influences and elements of uncertainty:
