... deterministic effects (mean wind, tower particularly during start-up, which can cause voltage shadow) and stochastic variations due to turbulence. The collapse e.g. after a fault on the grid. To overcome such deterministic and stochastic parts are added together in order stability problems, the use of power electronics in wind to get the ...
