    ...run some gas turbines spinning on idle.  

    i'd keep those spinning at 120% of power and use the spin to get them burning whenever you are near full load.

    to keep gas turbines on "hot standby" all the time.  Wind power "fades in" and "fades out" relatively slowly and can be predicted with good accuracy a few hours in advance.  There's plenty of time to take gas turbines out of cold standby.

      i was originally thinking of flywheels for Frequency
      stabilization and drop out, but realized that
      if you just used some power to keep the gas turbines
      spinning electrically they would add some electrodynamic
      mass to the network  and if you needed power,
      all you have to do is turn on the gas feeds,  the spin already is compressing the hot section,  it will come up to full power
      much faster.

      but if the predictions are that good, then thats less of an issue

      i know solar PV needs drop out protection.

      i wish every modern PV panel had some Supercaps
      on the back, to give you a minute or two of dropout protection and then feed DC downstairs so you could put some battery in parallel.
