Abstract: Grid-connected photovoltaic (PV) systems have become a significant area of interest for research scientists. Given this, this article presents a nonlinear control of grid-connected PV systems using active power filter (APF) with three-phase three-level neutral point clamped (NPC) inverter.
In a grid-connected voltage source inverter (VSI) with photovoltaic-fed (PV-fed) system, the connection to the three-phase power grid is realized through a DC-link and an inverter. This inverter could work with multifunctional capability, including APF and power supply (Valedsaravi et al., 2022b ).
It consists of a three- phase symmetrical grid; a SAPF based a three-Level NPC inverter connected in parallel with a nonlinear load through an output filter ff LR ; a PV array and a dc-link capacitor.
A three-phase inverter is interfacing with the main grid and local load through an LCL filter to decrease switching harmonics injection. The nonlinear and unbalanced load involving full-wave bridge rectifiers, series resistor and inductor is located in parallel at PCC. The whole system is connected to the main grid through the PCC.
The shunt APF control strategy has been presented to control the grid-side three-phase inverter current. A quasi-PR controller was employed to track the sinusoidal references properly due to the presence of nonlinear local load, containing harmonic pollution.
