flywheel to keep the Hz up to prevent blackouts

I suppose it had to happen these ugly blights on the tops of mountains can now cause blackouts ,  yesterday as I look around mountains (not much breeze) one or two turbines try to turn a little then fall back exausted. Not sure how this flywheel works ? , although it must take a lot of power to get it rotating. Glad to hear that they are now keeping Kilroot power station open (it was running  coal / oil and owned by the AES Corporation). In 2019 it was sold to a subsidiary of Energetický a průmyslový holding. They are going to converting it to gas.

EXCLUSIVE. £1MILLION was paid out to wind farm owners to turn off their turbines and stop generating electricity for Northern Ireland's power grid for 20 months.7 hours ago


And in january:-

Wind farms paid up to £3 million per day to switch off turbineswww.telegraph.co.uk › News › Politics

19 Jan 2020 - Wind farms were paid up to £3 million per day to switch off their turbines and not produce electricity last week, The Telegraph can disclose. ... the additional expense of a £1 billion interconnector that is itself proving unreliable.

  • Yes Clive I agree. Where does the energy required to get the flywheel back to speed come from? Of course how silly, more windmills. To store 30 degrees of phase error for the grid in a flywheel, it would need to weigh something around 100,000 tonnes, and would be very dangerous indeed if anything went wrong and it got free. The steam turbines can virtually instantly get more steam as required to correct the phase error, and the inertial energy storage requirement is quite small. That is basically how the speed governer works, from the reactive power measurement.
