This paper discusses the performance of a large-scale
grid-connected photovoltaic system (GCPS) under unbalanced
voltage sag conditions in the grid. By applying the droop control to
address the low-voltage-ride-through (LVRT) capability, the
output currents are no longer sinusoidal due to the oscillations
produced in the current references. To deal with this problem a
moving average filter (MAF) technique is proposed. Beside this
application, there are other advantages of applying the MAF which
are described in this paper. Selected simulation results using
MATLAB/Simulink for a 1-MV A GCPS confirm the effectiveness
of the proposed method.
