Contribution to the optimization and control of a photovoltaic system connected to the grid based a five levels inverter

This paper is aimed to optimizing and improving the performance of a Photovoltaic system connected to the Grid based a five levels inverter using conventional and advanced methods. The MPPT methods considered in this study include Sliding Mode Control (SMC) and Perturb and Observe (PO). We used a five level inverter controlled by passive methods to connect the PV system to the grid. The DC link voltages are controlled by using a closed loop called clamping bridge and an adaptive fuzzy logic PI controller (AFLC-PI). A PV model and power converters are modeled in Matlab SimpowerSystems toolbox and the MPPT and control algorithms are tested under different operating conditions to analyze the performance and limitations of each algorithm.
