Crucial Frequency Deviation Of The European Electrical Interconnected Grid (UCTE)

The frequency of the European Interconnected Electrical Grid (UCTE) is under stress. The frequency should be 50 Hz ... as you know. Click HERE for an UCTE background paper. Click HERE for details and basics of the Nordic Grid.

The network frequency is uniform in a power supply network and, apart from minor deviations from the nominal value, constant over time. The frequency changed today and earlier more than what usually is expected.

Here is some information about todays situation at 11:00 a.m.:
