Power output fluctuations from wind farms due to wind variations - A numerical model
report
One of the main problems of large-scale wind energy integration is the
maintenance of high quality ofsupplied electric energy. The variability of the power
output from wind energy systems may lead to large frequency and voltage fluctuations
in the grid.
To control this problem, knowledge is required about power output fluctuations of
wind energy systems. Hence there is a strong need for an accurate prediction ofthese
fluctuations.
This report describes a first set-up of a model which can calculate the time dependent
power output from wind farms. First, an outline is given ofrelevant factors in relation
to the time dependent behaviour of wind farms. Second, the developed model is
described. Third, an example calculation is given which illustrates the time
dependent behaviour of a wind farm in ‘bad weather’ conditions. The report closes
with suggestions for further developments of the model in relation to possible
applications. Those suggestions include a validation of the model against
experimental data
