Abstract— This paper presents a simplified model to
represent a wind farm in a power flow study. This model has
been developed taking into account the variability in the
generated power from windmills and its normal operation. Its
main advantages are its simplicity and the possibility of
calculating the voltage in the park’s network without having
to run a power flow study. Another advantage of the proposed
method is that it is based in the fourth-pole theory, widely used
in electrical engineering. Finally, the uncertainty of the model
is assessed.
Up to now, distributed generation in Spain must inject
power with unity power factor. But directive is going to
change and some feasible regulations for reactive power are
studied, attending specially to voltages across the grid. One
possible application of this model is to study the management
of reactive power in wind farms. Other possible application is
to study the influence of nearby wind farms.
