Dear All,
You may remember my post dated October 24, 2021:

One year and one day later:
My wife Ingeruth passed away on October 25, 2022 after a long lasting and serious illness at the age of 69. Ingeruth suffered ALS which was diagnosed in January 2017. One of our daughters and I nursed her 24/7 since then. She needed air ventilation all day and night … and electric power 24/7 …
"The U.S. Department of Energy (DOE), global equipment suppliers, and other stakeholders announced the establishment of the Electric Energy OT Security Profile working group hosted by the International Society of Automation ISA99 standards committee.
The Electric Energy OT Security Profile will be a cybersecurity work product utilizing the ISA/IEC 62443 series of standards. The final product will be a formal ISA/IEC 62443 application guide, recognized globally as the consensus work product for securing various control systems used in electric energy generation, transmission, and distribution operations.
...
The ISA Electric Energy OT Security Profile working group is seeking participation from industry groups, including the Institute of Electrical and Electronics Engineers (IEEE), the International Electrotechnical Commission (IEC), the International Council on Large Electric Systems (CIGRE), and other industry stakeholders to ensure consideration of and alignment with other cybersecurity work product development efforts. ... "
In mehreren Pilotprojekten erprobt die Netze BW den Einsatz der FNN-Steuerboxen. Die Steuerboxen kommunizieren mit dem Steuerbox Administrator-System mittels IEC 61850.
"„Die Erkenntnisse aus den Prüfungen im Karlsruher Labor und aus der gemeinsamen Arbeit fließen laufend in den Fortgang der Standardisierung zurück und dienen beispielsweise dazu, die Spezifikation zu präzisieren“, erklärt Jana Brandt, die in diesem Bereich zuständige Projektleiterin ist. ... Die Projektleiterin ist überzeugt: „Für den Bereich Technik & Innovation der Netze BW erweitern sich durch die Erkenntnisse die Optionen für die Netzintegration der E-Mobilität.“ ... Jana Brandt: „Zusammengefasst geht es um einen Beitrag zu Stabilität und Sicherheit im Verteilnetz, die Vermeidung von Kosten für den Netzausbau und somit letztlich zum Gelingen der Energiewende.“"

In my career as electrical and IT engineer I have experienced that engineers are quite often not invited to discuss the measures and plans for critical infrastructure protection with IT personnel.
It is completely different compared to the world of electric power system protection - I mean the applications of protection relays. Protection engineers are (in my understanding) the most crucial engineers. They are very important for the reliable delivery of electric power. Protection engineers are likely to attend any meeting when it comes to the reliability of the power flows. Protection engineers know what to do ... software people may help to implement the "what" and the IT personnel may help to solve the communication issues ... but the crucial parts are dominated by protection engineers!
Mr. Vytautas Butrimas, a globally well known engineer involved in cyber security of control systems has briefly discussed the "Berlin wall" between IT personnel and plant engineers.
Click HERE for the four page paper written by Mr. Butrimas.
Either of the groups involved believes that his or her group is the center of universe. There is little communication between the IT personnel and the engineers.
There are so many semipermeable walls between, e.g., politicians, company lawyers, economists, IT experts, and plant engineers. There is usually no way that experts from any layer are allowed to talk to the experts from the other layers. In the end: Each layer feels independent of the other layers ... which leads to what we see these days ... and may be even more in the future. Have you heard of a discussion between a power protection engineer and a lawyer or even a medical doctor?
It would help medical doctors to understand the basics of electric power system reliability ... and so on. Because medical doctors (and all other people of a society) depend 100% on available power.
So in the end: (Electrical) Engineers should be honored by the society ... the problem may be that the engineers are not wearing white coats but wear safety boots, safety helmets, goggles, protective gloves, ... a single doctor may harm a few people ... a protection engineer may harm millions of people during a blackout caused by a misconfiguration of protection equipment.
I remember well the discussion on understanding and using UTC Time in IEC 61850 ... a very time consuming discussion. There are still discussions going on ... should UTC be replaced by something else?
Whatever format and scale you are using or inventing ... you will see problems over a longer period of use.
These days we see even cars may have crucial issues with processing of time:
Honda, Acura cars hit by Y2K22 bug that rolls back clocks to 2002:
The report starts with: "Honda and Acura cars have been hit with a Year 2022 bug, aka Y2K22, that resets the navigation system's clock to January 1st, 2002, with no way to change it."
True? Yes, it seems to be true.
A well known issue is related to the year 2038: Year 2038 problem
Many other time formatting and storage bugs!!
Use the time you have in 2022 to spent more of it for or with your family, friends, ... stay safe in 2022!
Happy new year!
Lesson learned: Don't expect that more automation, more programs, more smart phones, ... give you any additional time in your life! I guess they will consume a lot of your free time to find and fix bugs of many kinds ...
IEC TC 57 just published one of the most crucial parts of the standard series IEC 61850:
This second edition of the 548 pages long bilingual standard (EN/FR) has been developed over a period of - I guess more than 10 years - taking into account the experience with IEC 61850 in general and with distributed power systems.
Now it is time to implement and use the standard in conjunction with the other core parts like IEC 61850-6, 7-1, -7-2, -7-3, and 7-4.

Aunshul Rege announced the latest Critical Infrastructure Ransomware Dataset (Friday Nov 05, 2021):
"Dear all,
I hope everyone is doing well.
My team and I have updated our dataset of critical infrastructures ransomware incidents (CIRW) that have been publicly disclosed in the media or security reports. CIRW dataset version 11.6 now has 1066 incidents, which are assembled from publicly disclosed incidents between November 2013 and October end 2021.
Also, community members can now submit a CIRW that you would like to see included into this dataset!
To download the dataset or submit a CIRW incident, please visit https://sites.temple.edu/care/ci-rw-attacks/. Please ensure that you enter your email address correctly, and note that we do not reply to personal email addresses (protonmail, gmail, etc.). And please give us a few days to respond to your request."
Please note the following information made public by US-Cert_CISA ... in case you use SIPROTEC 5 Relays:
EXECUTIVE SUMMARY
CVSS v3 9.8
ATTENTION: Exploitable remotely/low attack complexity
Vendor: Siemens
Equipment: SIPROTEC 5 relays
Vulnerabilities: Classic Buffer Overflow
Successful exploitation of these vulnerabilities could allow an attacker to cause a denial-of-service condition or trigger a remote code execution.
I just read that in the western part of the city Frankfurt (Main, Germany) the electric power was down for more than 10,000 customers. A current transformer (CT, for measuring the current) blow up ... and produced a lot of smoke. The power went off from 17:15 on Tuesday 2021-10-26. The restoration took some eight hours!
The Hessenschau (de) reported that nine (9!) people that depend on breathing ventilators had been hospitalized. This critical situation tells us, that the ventilators did likely not have battery backup power - either in the devices or external. The devices we use for my wife have both two internal batteries which give (rated!) power for 16 hours for each device.
This brings two questions up in my mind:
Instead of bringing patients with the ambulances to the hospital, it would be much easier (faster and cheaper) to bring an emergency power supply package (batterie plus inverter) to the patients! Or?
There seems to be a wide area of improving the quality of life.
By the way, why did the CT (current transformer) crash? Was it too old or not ... or? I hope that my friend Andrea Bonetti (one of the most experienced protection engineers on this planet) will comment on the importance of CTs!
Any comment?
Add on (2021-10-30):
First: The utility has told that more than 100 workers are involved in fixing the problem ... the current fix is provisionary only! 100+ workers means: It must be a big problem that needs so many people to fix.
Second: It was reported that in an elderly care home the nurses had to use their mobile phone's flash light to look for the elderly people ... no emergency light! Hmm ... strange. A few 12V batteries and some 12V LEDs would have done a good job! Cheap and useful ... lifesaving! ... if somebody would care for their maintenance. The management has obviously decided to purchase a hand lamp per floor ... 👍 something is better than nothing. Note: A battery leak (AA or AAA batteries) may damage a flash light that is not used often ... or only in case of emergency. Non leaking batteries are available: Lithium Batteries are the right choice for emergency devices. I have replaced the typical AA and AAA batteries with Lithium batteries for all flashlights and outdoor devices like thermometer ... they withstand cold weather and do not leak ... life time likely 10+ years ...

Please click HERE to find a good description of the IEC 61850 Tissue process as defined by IEC TC 57 - written by Christoph Brunner.
The tissue database was designed by my son Michael Schwarz and myself in 2004. At that time we exchanged tissues, questions, discussions, results ... by email ... and somebody took note of the discussion and wrote something into the tissues word document ... huch ... which was the latest version ...? Quite confusing.
NettedAutomation wanted to offer a free of charge service to the community that allows everybody to post any new tissue on a single entry point ... and to get a single, always up-to-date list ... Since then we have improved the tissue database according to the experience made by the global community.
Nowadays the tissue database is an integral part of the IEC 61850 and related standard series like IEC 61400-25 ... all new editions of any part of these series has a list of tissues taken into account in the new edition, e.g., in the name space document of part 7-4:
IEC 61850-7-2 2007A3 NSD light code component, see the IEC 61850-7-2:2010 for full legal notices:

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..."

You may be surprised about the fact that I posted very few information on this blog for some time. Let me explain our family situation here at home. I received an email today from a colleague and follower of this blog. This email encouraged me to publish excerpts from the emails we exchanged and to add some thoughts at the end of this post:
Email I received on 2021-10-16:
"Dear Karlheinz,
Perhaps you remember me, I've long been a keen follower of your blog on IEC 61850, and we have exchanged e-mails a few times in the past. ... I am writing to you because
I remain looking forward to any news from you ... Kind Regards ..."
Email I sent on 2021-10-16:
"Dear ...,
I am sorry to read these lines ...
I have changed my work (now being retired) to nurse my wife 24/7 … she was diagnosed ALS in January 2017. We are happy that the Lord Jesus has helped us to do that work together with one of our daughters. My wife needs non-invasive ventilation around the clock … we are still together … which is very good.
So, as a consequence I have more or less stopped my business …
Have a great weekend!
Best Regards,
Karlheinz"
Email I received on 2021-10-24:
"Dear Karlheinz,
I am very sorry to learn that you stopped your business because your wife is seriously ill.
To be honest I had realized that the frequency of your posts had declined in the last months... Your blog was a wonderful source of information and it will be missed by the smart grid community. Your posts were real, technical, relevant, useful stuff and not the usual buzzword-laden, over-hyped bullshit we are all used to read these days.
Given the circumstances, I believe no one will say you didn't do what was your duty.
I wish all the best to you and your family."
Some Thoughts to think about:
Megger AB, Stockholm, Sweden is using IEC 61850 for various reasons in the electrical testing domain.
Andrea Bonetti is senior specialist in relay protection and IEC 61850 applications at Megger. Andrea has written a very interesting article in the latest issue of Electrical Tester magazine of Megger:
The importance of IEC 61850 in relation to the smart grid
He concludes: "Economic electricity supply: We need to study and get used to IEC 61850 methods, but once this is done, the economic advantage is evident: reusability of previous projects, shared understanding, focus of the technical community on solving common problems, and concentration of the resources.
In conclusion, I hope it is now clear that IEC 61850 is not just a communication protocol but a complete philosophy for electrical systems. So, next time you have a smart grid project, please try to answer this question: How much of IEC 61850 am I using in my project?"

The abbreviation "IEC 61850" could be found 100 times throughout the magazine! ... in conjunction with testing, smart grid, ...
