Its not my field, having worked with picowatts rather than Terawatts, but I believe grid level converters - at least the big ones used on HVDC links - do not run at high speed. They are quite crude and some even simply chop DC at Mains frequency to produce a square wave and rely on subsequent L-C filtering to get a sinusoid. More sophisticated ones manage a sort of multilevel boxcar waveform to approximate a sinewave more closely. They too operate at low speed, a few multiples of Mains frequency.
Having now read up on MMC high voltage converters, its a concept I had totally discounted for the grid because I didn't think capacitors could exist for that function at that combination of frequencies, voltage, power and charge, they must be physically massive which in itself must create other complications.
Likewise on power, one of my specialisms was down at the < -130dBm signal levels - but not at audio frequencies. Those days have well gone as has the grey matter.
There's a real danger that the left will drag Britain back to the 1970s, with secure well-paid jobs, ample housing, properly-funded NHS and social care, free tuition, student grants, final salary pensions, affordable rail fares and fabulous films and music. David Osland 2025

The internet at its best, Wirral will be entirely under water by 2050, we are notorious for having four tides a day and we live in the "town" of Merseyside. That is why the are building the barrage.

Once again I am amazed at the quality of American education.
The internet is becoming more and more financially driven, very little effort is put into content, much more effort is put into expanding articles to obtain more advertising time hence revenue. In this case I suspect some of the content is AI derived because you can see how stated "facts" are linked to reality but miss by a sidestep.
