Abstract (EN):
The wind systems have become more and more complex, namely due to
increase of the turbines and wind farms power, what implies higher significance of
either system non-linearities or system multivariable characteristics. It adds as
direct consequence from wind systems high power that wind farms are becoming
active elements in the wind power system. So the wind system performance and
behaviour become critical elements of the grid. The performance of the turbine
control is improved keeping on the power coefficient always near to maximum
value, optimizing the energy extraction from the wind speed and so increasing the
global system efficiency. It adds that the operation within a wind farm context
demands for optimization of the whole operation. This chapter analyses wind
systems biased by the increasing of wind power penetration into the grid and intends
to deal with the requirement of controlling either each wind system or wind
farm pointing out a methodology to design fuzzy controllers in order to optimize
turbine operation and farm operation taking in accounting its operation as power
system element. Some results are carried out to validate main conclusions, namely
the need of including in the control process data on very short-term wind condition
through adopting new techniques of real-time forecasting.
