global frequency average - regional scatter
Aug 04, 2019 16:51 The frequency is considered to be approximately identical at any place in Europe. However slight differences can be seen at very high temporal resolution of the frequency. While the frequency still looks almost identical in the seconds range, small differences appear in the tenths of a second range.
Switzerland was on the verge of a blackout
Jun 10, 2019 14:10 On 20 May 2019 n-1 violations occurred in Switzerland which in connection with a forecast deviation and strong electricity exports nearly led to a blackout in Switzerland!
Long term analysis of grid frequency proves renewable damping effect on grid
May 20, 2019 07:00 We had already investigated the stabilizing effects of renewable energies on the grid. The biggest frequency deviations still mainly occur directly after the hour break and interesting conclusions can be drawn from around this ...
Mains frequency dips to 49,84 Hz on 03.04.2019 at 2100 hours
Apr 04, 2019 14:10 On the evening of 03.04.2019, an under-frequency event occurred, similar to the event on 10 January 2019. At the moment, it is not possible to determine the exact cause, but the grid frequency dropped to 49.84 Hz at 21:02:30 CEST, outside the normal range.
German renewables have a stabilising effect on the interconnected grid
Mar 08, 2019 08:20 Strong systematic frequency fluctuations in the European power grid often coincide with the transition of successive standardised trading products. Interestingly enough: the feed-in priority of wind and PV has a dampening effect on the frequency deviation and stabilizes the overall system.
A brief overfrequency event on Jan. 24, 2019, at 6 a.m.
Jan 27, 2019 01:10 On the morning of 24.01.2019 at 06:00, there was a brief overshoot of the frequency in the European power grid. The frequency averaged over 1 second was briefly 50.193 Hz in some places, i.e. close to the 50.2 Hz limit. The extent of the frequency deviations varied regionally...
