Analysis of Harmonic Reduction Using An Intelligent Control Active Filter in A Solar Grid with Variable Load

Electricity quality maintenance is severely hampered by the integration of solar electricity into the grid, especially when there are changing loads and harmonic disturbances. This study suggests an intelligent control active filter for harmonic reduction in a solar grid with changeable load conditions as a way to address these issues. The efficacy and adaptability of traditional passive filters are limited, so innovative control strategies must be used to mitigate harmonics effectively. This study looks at a grid-connected photovoltaic system's static variable load. The integration of grid-photovoltaic assembled a reversible converter to make the suggested system more efficient in power disturbances. The power circuit consists of two 75-watt series photovoltaic panels connected to a DC-DC static variable load. Additionally, an intelligent control active filter with a basic design is intended for harmonic reduction. Current control of the reversible inverter to reduce fluctuation under static load variations and synchronize the output current to the alternate grid voltage. The current photovoltaic grid system is capable of switching the direction of active powers in the alternative grid for static changeable loads brought on by reversible converter design, according to results obtained using MATLAB/Simulink for easy access, a categorized list of 38 publications on the subject is also provided.
