Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
The study is here.

Disconnected patches and strips is indeed the 'solution', check the example diagram on page 31 (you can even have a single tightly-spaced wind farm with the turbines placed on several separated but nearby suitable areas of less than a kilometre across). This also reduces the applicability of the 1 MW/km² figure for large contiguous windfarms.

They used two reference wind turbines (one weak-wind one strong-wind), and an iterated placement with a minimum spacing of 456 m (four times the [larger] rotor diameter of the weak-wind turbine). With a triangular grid pattern on a large uninterrupted suitable area, I calculate 17.77 and 18.88 MW/km² as maximum density on actual land area (as opposed to the area of the patches of suitable land) for the 3.2 MW resp. 3.4 MW reference turbines.

Thanks DoDo, looks good.

I found that Jacobson has also studied this problem, arriving at considerably higher average power densities: ~ 4 MW/km^2.
