Study of Fuzzy Logic controller based MPPT and the PO for the Z-source inverter integrated in PV system

摘要

The photovoltaic (PV) generation system becomes important as renewable energy sources, due to its advantages such as absence of fuel cost, low maintenance requirement, and environmental friendliness, the integration of the z-source inverter in the (PV) generation system has been very popular among researchers, due to its ability to boost the PV voltage with its single-stage topology. This paper focus on the integration of The Z-source inverter in a photovoltaic (PV) system generation, and the implementation of the Perturb & Observe (P&O) and the fuzzy logic controller algorithm (FLC), to find the Maximum power point (MPPT). At the final we compare the results of the FLC with the Perturb & Observe (P&O) algorithm. A Matlab simulink toolbox and M-file have been used for the simulation, in order to verify the results experimentally. The two algorithm was implemented in a real time with a dSPACE MicroLabBOX, and the I-V curves was programed with Chroma 62150H-600S/1000S Solar Array Simulator.
