An integrated function of photovoltaic generator supplying to nonlinear load: Active power filter

The PV generation is increasingly popular nowadays while typical loads require more high power quality. Basically, one PV generator supplying to nonlinear load is desired to be integrated with a function as an active power filter (APF). In this paper, the proposed three-phase three-wire system including PV generation, DC/DC boost converter to extract maximum radiation power by using MPPT and DC/AC converter to acts as an APF will be presented. The instantaneous power theory is applied to design the PV-APF controller which shows reliable performances. The Matlab/SimpowerSytem tool has proved that combined system can simultaneously inject maximum power from PV unit and compensate harmonic current drawn by nonlinear loads.
