Typical Russian attitude - colonize other nations and act like they owe you

The last couple of years I have been working hard at not directing my animosity towards the Russian state against Russian people. Post like yours makes that much harder. Almost no other people will glorify their past and current crimes like Russians do.

The clearest term IMO is synchronous capacitors. They are in effect large flywheels that can operate as both an electric motor and a generator. Over time they are a net power drain for the grid, but as parent says offer synthetic grid stability independent of power sources.
Very interesting. I'm wondering whether distance and "direction" are an issue here? That is: over large distances (how) would (light speed) latency translate into phase change if "downstream stabilization" suddenly becomes "upstream". (Sorry for asking such a poorly stated question that I really haven't thought through — I know very little about electricity and you seem to understand quite a lot about this subject.)…
Good instinct. There is a site that measures frequency in several places in Europe and shows the phase difference. [0]
The phase difference is not really about distance it's more about energy flows, where it's lagging there more power is used and where it is leading more power is generated. The flow will be from early phase to later.

For the most part the Balic was conquered by the Russian empire, mostly from Sweden and Poland.
When the Russian Empire took the Balic states the restored and increased Serfdom to the strongest it has ever been.
Russian Empire and the Soviet Union have been horrible for the Baltics literally for 100s of years.

I'm sure Russia was providing that infrastructure for free and didn't take anything from other countries while they were in the USSR.

As the quote goes, "All animals are equal, but some animals are more equal than others." Pretending Russia didn't have a special status in the USSR doesn't win points in an argument, it just makes you look misinformed.

So I imagine phase difference can be a serious issue, or at least something that needs to be mitigated and monitored continuously (evidently). I'm assuming a DC power network intrinsically solves this (in case of solar energy).
But how would current and voltage be stabilized in that case? Just huge capacitors? Chemical batteries?
