The future you have been dreaming of since you were a child exists in a marketing brochure produced by a start-up that is still starting up and has yet to actually produce something more than a sombrero sized monstrosity and some 3D renderings.
A few years ago I bought a colour laser network Brother printer. Prints good Hasn't broken down No ink to dry out Cheap printer Cheap toner Full-duplex printing Builtin network Drivers for windows, mac, linux. Apparently it works on Android and iPhones too.
I guess that's why the "Tech specs" page for the mac mini only says " dual-core Intel Core i5 " so it's not quite as obvious it's a 4000 series mobile CPU from 2014.
The entire article is about Australia and its power grid. I know Australia is pretty shit when you compare it to New Zealand next door, but it's not a third world country.
If you're not implying Australia is a third world country, you're completely off-topic.
Now instead of a mistake causing a server to be open to your intranet, it's now exposed to the entire internet on a platform constantly scanned for unsecured servers.
It was contracted to back up the SA grid. It's stealing the jobs of VIC power stations! It's making the backup station that was contracted to fix this issue look bad, even though it kicked in after 4 seconds and was only required to respond within 6 seconds. It's even making the monitoring systems look bad. It started correcting the grid faster than the monitoring system was sampling.
How does pumped hydro at a hydro plant help in these sorts of problems? You generally get more than a few seconds notice that your hydro storage lake is empty.
I no longer have to worry about the computer cutting out, since my laptop/tablet/phone has its own battery.
I don't think my kids have ever experienced a power cut. One of them is 8 years old. The odd one or two in the last decade have been at night while they were sleeping.
I've only experienced one in the last decade. The other few I only noticed because the clock on the oven reset. There's been a few brown-outs, but not enough to cause electronic devices to glitch. They all work down to 90V and a brownout still delivers maybe 200V.
If you buy something with a US/Japan plug, a pair of pliers can fix it, providing it can take 240V. And you're comfortable with the fact the pins might fall out and be left sticking out of the socket. And that they don't have the mandatory insulated section for finger safety.
My house was also built in 1980, it had two outlets on opposite sides of each room. With the dodgy ring foundation and piles, it's pretty easy to get extra outlets installed though.
200mHz would effectively be DC. You wouldn't be able to make transformers that work that slow. They would need to be huge and the losses would be huge as well.
The grid wasn't short 500MW, it was down a 500MW power station. Since the battery only needed to supply 7MW to correct the frequency, the grid was only short 7MW.
To say it was short 500MW would be assuming every power station running before the incident was running at maximum capacity. If that were the case, the back-up stations would have already been bought online.
Can you explain how you inject voltage? Voltage is the amount of charge each electron has. Current is the movement of electrons. Power is the product of the two.
I can explain how they boosted the frequency by injecting power though. When the turbine based generators get overloaded, they slow down, lowering the frequency. Injecting power slightly ahead of phase reduces the load they see, so they speed back up.
Yeah, the ISS constantly gets destroyed by space junk. GPS satellites also only last a few days before they're destroyed too. The real reason they stopped the moon missions was the difficulty they were having flying through the junk to get to the moon.

Except this is an article about people who don't print enough to stop an inkjet printer from drying out.

Prints good
Hasn't broken down
No ink to dry out
Cheap printer
Cheap toner
Full-duplex printing
Builtin network
Drivers for windows, mac, linux. Apparently it works on Android and iPhones too.

... hence why they have a battery, since it can respond in milliseconds while backup systems spin up.
It took it back over 49.80Hz, which is the lower normal limit. The backup power station then finished starting up.

It was only readable to people with an AWS account.
Because now people can find all the jews/muslims/blacks/whites/mexicans/etc for their hate crime victims.

There was a grid-scale backup generator to handle this exact situation.
It's startup time SLA is 6 seconds, it took 4 seconds this time.
It was contracted to back up the SA grid.

200mHz would effectively be DC. You wouldn't be able to make transformers that work that slow. They would need to be huge and the losses would be huge as well.
Edison would have been happy though.
It didn't respond too rapidly. The frequency was below the absolute minimum of 49.85Hz for normal operation.
Just putting out a wild idea: they configured the battery to kick in at 49.80Hz on purpose.
The grid wasn't short 500MW, it was down a 500MW power station.
Since the battery only needed to supply 7MW to correct the frequency, the grid was only short 7MW.
To say it was short 500MW would be assuming every power station running before the incident was running at maximum capacity. If that were the case, the back-up stations would have already been bought online.
But then the positive terminal would have a negative charge and the negative terminal would have a positive charge.
