Basics For The Future Electric Power Systems – Some Thoughts

Smart Grids, Energiewende, renewable energy, ... Digitalisierung (digitization) der Energiewende, ... are buzzwords for some years. What is really needed for the future electric power systems?

Against the background of the ongoing discussions by engineers, lawyers, politicians, other people ... with a degree in the social or natural sciences, graduate engineers, medical doctors, lawyers, and graduates of business studies and economics, it may be helpful to look at the real needs that are related to the physics ...

I have written a one page document:

Basics for the future electric power systems – some thoughts 

It starts (de and en):

"Das zentraleuropäische Verbundnetz UCTE ist eine der größten Maschinen (oder gar bezüglich der Leistungsfähigkeit der Energiebereitstellung weltweit die größte Maschine) auf unserem Planeten. Bezüglich der Ausdehnung wird dieses elektrische Netz nur von dem inzwischen weltweit ausgedehnten Kommunikationsnetz übertroffen. Alle diese technischen Netze folgen dabei strikt physikalischen Gesetzen – egal, von wem sie und zu was sie genutzt werden oder auch welche Ideen am Markt gerade en vogue sind..."

"The central European interconnected network UCTE is one of the largest machines (or even the world's largest machine in terms of the performance of energy supply) on our planet. In terms of expansion, this electrical network is only surpassed by the communications network that has now expanded worldwide. All these technical networks strictly follow physical laws - regardless of who uses them and for what they are used or which ideas are currently in vogue on the market..."

Updated Mains Frequency Information Service Has Been Launched

Please not that the updated Mains frequency information service has been launched yesterday. 

The mains frequency info service is now active. 

You will now receive messages about unusual mains frequency behaviour.

For information on the messages, please refer to the website www.pc-projekte.de.

The website offers non-commercial information newsletter for the continental European network RG-CE (UCTE)

In this test group, you can register for an automated newsletter "Netzfrequenzinformation Verbundnetz RG-CE (UCTE)", which will provide you with the latest information on network frequency measurements.
Experience has shown that the measuring systems recognize and report approx. 4-6 messages per week on a daily basis.
You can find much more information about the grid frequency HERE
This service is a very huge offer to the power systems communities in Europe. I haven't seen anything comparable ... and all for free!

UPDATE 2021-01-23: EXTREMELY Crucial Frequency Deviation Of The European Electrical Interconnected Grid (UCTE)

 Dear All,

You may have heard that on January 08, 2021 Europe was hit by very serious power problems that entered almost to a very big blackout.

Message time : 08.01.2021 14:05:12 MEZ
Message : UCTE low frequency
Mains frequency : 49,746 Hz
Mains load difference : -3741,4 MW

There are many publications on the Internet ... please search for UCTE blackout January 2021 ...

UPDATE 2020-12-10: Crucial Frequency Deviation Of The European Electrical Interconnected Grid (UCTE)

Dear All,

Due to the increasing number of frequency events I have decided to recommend you the following ... it is too much work for me to post the newest events ... sorry for that:

1. Register to receive the event reports directly from one reliable source 

A look at the following private website (offered by an experienced senior electrical engineer) provides very informative and easy to use information (right part on the figure):

www.pc-projekte.de (the content can easily be translated - with Google)

You may register to receive messages like the one above:

https://pc-projekte.lima-city.de/ucte-netzfrequenz-infodienst.html

Note that these messages carry just privately generated information about specific events of the frequency of the ENTSO-E Network in Continental Europe (former UCTE).

2. Check the following website:
There you can find a list of frequency events ... 135 in 2020 already !!

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.:
