Electric cars? for Aspies, Narcissists and Power Grid people

Maybe there is someone on here who can answer a query I've had in the back of my mind for some time...

As I understand it, the stability of the grid system relies on the biggest producer setting the frequency, and minor producers matching it. Is this correct? and if so, what happens to the system when there are more and more producers but putting less in each?

The grid frequency varies slightly as demand rises and falls as it is, so I'd imagine it's going to be a nightmare keeping it stable as the grid becomes more and more complex.

Any electrical engineers here? Is this a solvable problem? Is it even a problem?

I am an electrical engineer but my specialty is not grid power however my understanding is with renewable energy there are more immediate/short term problems as there are larger fluctuations with supply hence you need batteries to provide instant power.

Grids these days are smart and so act quickly to balance power via batteries, gas turbines and hydro. The base load provides inertia which is not present with renewables. I believe that that is where there will be problems while we slowly change our power generation.

What is electricity grid inertia?

It is vital to maintain an electrical grid's system inertia under all network conditions, no matter the source of generated power.

I am not an electrical engineer, but I did read some where that the big Tesla battery in SA was being used to maintain grid frequency and was doing so better than power stations.

Post it in General Chat, under this thread IMO.

The future of energy generation and storage​

 
It appears outer suburbs are now most popular with EVs.
It appears people who travel long distances to work are the guys buying EVs to reduce costs. No longer the domain of this heading?

The analysis of sales from Australia's two top electric car manufacturers showed drivers in outer metropolitan suburbs purchased more than 26,000 battery-powered vehicles in the past year, or more than 43 per cent of all EVs sold.

Some 427 electric vehicles were registered in the Victorian postcode 3030, which includes western suburbs such as Werribee and Point Cook, in January which made it leading postcode for electric vehicle registration, according to the AAA.

That was followed by 2113 (covering Macquarie Park and North Ryde in Sydney's north) with 420 registrations; 2155 (covering Beaumont Hills and Rouse Hill in Sydney's north-west) with 418 registrations; 4217 (covering the Gold Coast in Queensland) with 369 registrations; and 4069 (covering Kenmore and Chapel Hill in Brisbane's west) with 350 registrations.

Inside the suburban electric vehicle boom: The postcodes leading the race

Outer suburbs are becoming hotspots for electric vehicles, with new figures showing the low-emission cars are more popular there than inner-city suburbs.

BYD is one of the sponsors of the Euro-2024 football tournament, and thousands of German fans interested in its advertising went to the manufacturer's website. And, since the national domain in Germany is .de, they all went to the sex shop's Buy Your Dildo website, located at http://byd.de.

As a result, the website's founders had to put up a special text for soccer fans from Germany with the message: "If you are looking for a Chinese car manufacturer, you will find it at http://byd.com."

Germans knew where they were going.
