Enhancing Grid-Connected Hybrid Renewable Energy System with Super Lift Luo Converter for Improved Power Management and Reduced THD

In recent decades, use of renewable energy sources (RES) has become increasingly popular due to its reliable and clean source of electricity. Utilizing RES like solar and wind helps in ensuring energy sustainably. Furthermore, it is admirable to employ renewable resources popularly in order to generate energy that is both affordable and dependable. Solar and wind energy sources are intermittent, and their energy output can vary due to weather conditions. Combining them helps to mitigate the variability in power generation. In the proposed work in combination of solar and wind turbine source is implemented for increased system reliability with minimized cost. The proposed approach uses Super Lift Luo Converter to boost up the voltage generated from PV system. The employed Proportional Integral (PI) controller regulates the converter operation and aids in the generation of a stable voltage at the DC link. A similar process ensues in the Doubly Fed Induction Generator based Wind Energy Conversion System, which produces AC voltage that is converted into DC by a PWM rectifier to supply the DC Link with input power. In case of excess generation of energy from the hybrid systems, a battery is utilized for storing energy. For the conversion of DC electricity to AC, a three-phase voltage source inverter is supplied the DC link voltage. Grid synchronization is accomplished utilizing a PI controller, while the LC filter decreases harmonics. Grid synchronization is accomplished with help of a PI controller, and harmonics are reduced by an LC filter. The performance of suggested concept is appraised using the experimental setup and the corresponding results are verified utilizing MATLAB simulation. The proposed system operates at the efficiency of 96%, with reduced Total Harmonic Distortion (THD) of 0.93%.
