The above is not particularly helpful to understanding the event.
RE: Pakistan Blackout
Synchronised development of generation, transmission & distribution is definitely a crucial point.
What initiated the grid collapse and how it all happened in a second is still not clear.

And, when PG&E performs preemptive blackouts for days on end during the dry season, it probably feels pretty similar to Pakistan, in that moment.
Not to mention the rolling brownouts to prevent load shedding during the peak A/C season.

CA has limited transmission, and generation, and requires green energy, also the recent lawsuits for fires has made it clear that blackouts are more public friendly than starting fires.
Brownouts are the utilities way to tell you to cut back. The problem is people don't pay attention. Which maybe why the 19 is so bad in CA.
RE: Pakistan Blackout
I'll assume there's no racist intent in that. I was simply pointing out that in an unplanned blackout; you have no power and are in the dark, so which country you're in isn't germane, other than possibly the time it takes to get power back. Of course, Puerto Rico is ostensibly in the US, but is treated like like it's not, particularly during the Trump administration

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

If you are taking about COVID "19" the 19 refers to the year 2019 which is the year that the new SARS Novel Corona virus first presented itself. Hence it is known as COVID 19.

The management troubles are too old to blaim COVID for them.
https://www.dailyexcelsior.com/pakistan-power-outa...
... The officials admitted that the blackout had exposed the mismanagement on the part of the government in running the entire power sector of the country on an ad hoc basis, it said.
The chief executive officers of all the three key companies concerned — the Central Power Generation Company-Guddu, the National Transmission and Dispatch Company (NTDC) and the National Power Control Centre (NPCC) — have been working on ad hoc or acting charge basis for years. ...
My guess here - The holes in the cheese all lined up.
Technical fault at a power plant (do not know what this is yet.)
Transmission line protection settings so that the line did not disconnect the power plant for the technical fault.
The transmission line settings may have been adjusted to reduce tripping, something to do with this line should have it's insulators cleaned several times each year, but that has been deferred for several years.
A transmission system that at the best of times is only marginally stable.
And no confirmed chief executive officers to take responsibility. Sounds like a plan for loosing money - oh that is happening also, something called by IMF circular debt,

RE: Pakistan Blackout
Yes there are protection engineers in the power plants, but they are not always told about things that go on.
I was once asked from a powerplant manager, do we really need protective relays. I answered, only if you have a fault.
