Tell that to the German factories running synchronous motors that are
having f to intsall massive UPS/inverters because sudden fluctuations in
the mains frequency due to sun coming out/wind gust coming along are
destroying the machines the motors drive.

Some times I wonder if you actually believe all this ******** harry, or
whether its just you way of amusing yourself by pretending that you do,
or whether you actually are a SPIV and make a living out of selling
useless irrelevant technology to gullible people.

Ineptocracy

The reason the power from turbines is rectified then inverted via a
grid link inverter is so they avoid all the problems of
synchronisation.
In different wind speeds they need to run at different speeds to be
efficient.

Gosh! You don't say!

There are much bigger ones available too.

Wow!

So you half wit, the wind turbines are not synchonised with the grid.

Er, where did he say they were?

And PV panels generate DC so they are not synchronised either.

Where did anyone claim otherwise?

Which all goes to show how full of **** you are ranting on about
topics you have zero knowledge about.

You have just demonstrated you know f**k all about what happens to the
grid due to fluctuations in renewable energy.

MBQ

Grid tie inverters generate whatever frequency they "see" on the gird
connection. So their operation has no effect of the grid frequency.

Nonsense. If you introduce a sudden surge of extra current then it will
result in the grid frequency rising. The grid tie inverter will then
have to track it. So the cause is indirect, but it still happens.
