Performance of Three Phase Grid Connected Inverter for Low Voltage Weak Grid System using Super Lift Luo Converter

The implementation of a Fuzzy logic based PV grid system with reactive power compensation. Ina Fuzzy logic controller and inverter based system and MATLAB is used to perform simulation analysis. The solar system provides voltage to the inverter through super lift Luo converter with fuzzy based MPPT algorithm .This converter will reduce ripple contents in the voltage and maintain the constant voltage to the inverter system The three phase voltage source inverter will convert the constant DC voltage into two level AC output voltage .This AC voltage is given to the grid, the PV system reduces the PQ problems in the grid. As it can be placed near to the load centers when compared with other renewable souce of generation. A maximum power point is tracked using Super Lift Luo Converter with variation in the irradiations all throughout the year This paper proposes theory based current controlled PWM controller for the voltage improvemen. Low THD synchronized current output, and limited reactive power compensations are improved. MATLAB based simulation results shows the efficient working of rooftop PV with proposed control methodologies in grid connected mode with limited reactive power conditioning. This project is implemented in MATLAB simulation and experimental results.
