Mains power voltage drop to reduce usage?

Yes.

That is correct. What he said, was not.

There is a problem with capacitance and inductance sending high voltage underground or undersea for significant distances, which DC doesn't have.

Yep.

Well, I wouldn't say that as proof "it can be done". There were consequences :-D

...

Oh? I had no idea of that. Different islands, perhaps?

No, because existing equipment can not handle it. The regulation simply takes into account that equipment, those design constraints, and tells you not to drop the frequency.

Sure, go to your own island and put your own rules, from scratch, then talk.

Except of course that that is DC link - because it is underwater.

This one runs about almost 1000 km and transmits 2000 MW < if I'm reading this correctly >

Yes, true. But in this case, the losses using AC per kilometre are much lower, so the length at which DC becomes economical above ground is much greater than under ground or under water.

It is simply a question of calculating all the costs and deciding which one turns cheaper.

The network issue in Ukraine has been messy for years.

According to

In March, there is a limited connection to Central Europe.

I think there is in fact a connection now.

I read it somewhere - but lord knows where so call it 'unconfirmed' for now.

I think they probably could increase the low frequency bound for domestic and modest sized solar or wind farms not to drop off grid. It is preferable to stress a few motors and transformers for a few minutes when compared to the major cost of dropping large segments of load.

Otherwise you get the cascade failure mode that afflicted the UK after a freak lightning strike took out a fairly small electric plant and caused a cascade of failures that took down mains for London and much of England.

There is scope to modify the rules a bit so that losing 0.5Hz in grid frequency doesn't cause all local generation to drop off grid. Even in this rather bad case the generating companies got back to nominal conditions within 5 minutes but by then they had shed a lot of load.

Are you sure it was Oranges? Plums or Cherries would have been far more likely. Oranges grow much better further south.

They said they were oranges and they sure looked like oranges.

Some types of oranges and lemons grow well here, even in San Francisco, which is a lot colder than Cupertino.

The HP machine was basically a 16-bit PDP-8, a page-addressing machine with a couple of accumulators. HP also created a really slow, klunky hyper-CISC machine that wasn't successful. HP was stunningly not-creative when it came to computers.

None of the minicomputer companies survived, sort of like none of the tube or early semiconductor companies are still around, or at least still in the device business.

Intel is running on inertia now.

Yes, I have an orange tree in my back yard in San Jose. But, it's not optimal conditions as it does drop below freezing a few times each winter. Perhaps less so up the peninsula.

When I moved to Sunnyvale, there were still cherry orchards west of el camino.

HPIB interface was pretty good for scientific and engineering and their HP200 computers using 68k were OK. IBM PC's were very rough by comparison and their graphics truly abominable.

It was a long while before the 7220 was surpassed. I quite liked TI's

Their latest chips are still pretty good given the architecture. Pipeline stalls are much less frequent than they used to be.

sqrt on the i5-12600 somehow benchmarks faster than divide on mine! (it must be a quirk of how the thing pipelines instructions)

I think HPIB was abominable, but it was the only thing that worked at the time. Its only merit was that there were lots of electronic instruments that had that interface.

Has anyone read the original HPIB spec? There is a state diagram that will give you nightmares. And words that have to be translated into concepts like "logic high".

There was a hardware ack line in the cable. When SCPI began to be used over RS232 and Ethernet, ack was forgotten somehow. It's post and pray.

So not required. With wind turbines, you'd use the electricity obviously.
