It's difficult the know where to start here, but I'll have a go.
This is mixing topics, the two must be separated; frequency regulation and phase angle control.
"The Vector is making minute, in situ corrections with tiny amounts of current."It will be making (very roughly) around 20mA sized
adjustments to about 3 Amps of current. 20mA
is a tiny amount of current to a 3 ph supply, and nothing to do with micro Amps, the control signals will be higher than micro Amps.
"It does not require massive amounts of current because it is maintaining the synchronization."It requires the larger current corrections approx.
every 1/4 mains cycle, there's no such thing as "massive current now no longer required because it's maintaining the synchronization".
"Its like steering while driving, there are small corrections as you drive, not massive back and forth over steering (which would be the case using cap banks)."No, It's more like peddling up a quite steep hill, you can't just stop peddling once you've got the bike moving up the hill.
"It is true that if the power is perfect coming in the facility,"You probably mean, if the load(s) are already drawing their current in phase and balanced, which is a quite bit different.
"The calculation of efficiency is key here."ROTFL
"We are using 70-120W of power at all times to correct (bring to full synchonization and balance) of 60kW at all times."The 70-120W is just for the magic computing, the power control devices will use and dissipate more, especially if they're switching Amps at MHz frequencies.
"Don't forget surge protection,"I haven't! It doesn't do very much in the way of surge protection, the wires are much to thin!
"asset performance improvement"LOL How do the assets even know if the current in the supplier's transformer is balanced or not.
"The residential version is a trickier business case. Outside of high consumers of power or special cases like audiophiles,"Yeah, there's nothing there, even for audiophools.
"If a home has solar and an EV, the case becomes very clear though as it improves the output of the solar and charging times and rates of the ev charger"You've mentioned the correction of
the output power of solar and generators, for these devices does the VectorQ2 have to be connected backwards, think about it!
