Abstract :
The photovoltaic (PV) generation is increasingly popular nowadays, while typical loads require more
high-power quality. Basically, one PV generator supplying to nonlinear loads is desired to be integrated with
a function as an active power filter (APF) and fuzzy logic control. A three-phase three-wire system, including a
detailed PV generator, dc/dc boost converter to extract maximum radiation power using maximum power
point tracking, and dc/ac voltage source converter to act as an APF, is presented. The instantaneous power
theory is applied to design the PV-APF controller, which shows reliable performances. A Fuzzy Controller is
introduced in this paper in order to improve the system performance. The MATLAB/Sim ower Systems tool
has proved that the combined system can simultaneously inject maximum power from a PV unit and
compensate the harmonic current drawn by nonlinear loads.
