    Control design of Puc5-Based multifunction solar filter
    (2022) Djelloul, Ammar; Sahli, Mohamed Rafik; Khaldoun, Aissa (Supervisor)
    This work presents a Solar Photovoltaic Active Power Filter system (PV-APF)whose architecture basically consisted of a PV generator as primary renewable source three-phase double stage power converters (DC-DC, DC-AC), utility grid and non-linear load connected through Point of Common Coupling (PCC). In addition to the PV power injection the system intended tooperate as an Active Power Filter (APF) to filter the harmonic pollution form the non-linear load. Based on the p-q theory, the PV-APFextracts the fundamental and harmonics information from the polluted load current in order to estimate a compensating reference current that should be injected along with a maximum photovoltaic power extracting (P PV ). Moreover, we have investigated the use of new topology inverter that is thepacked U-cell 5 levels (PUC5) inverter and compared with the conventional two-evel inverter. The comparable simulations of the PV-APF based on each inverterrevealed the superiority of the PUC5 inverter in terms power quality improvement and achieved THD levels. According to obtained results of simulation, under standard test condition (STC) with a disconnected nonlinear load, the classical inverter measures THD of 1.24% in output current, whereas in case of using the PUC5 inverter and under the same conditions the THD was 0.19%.
