Due to their scarcity and exhaustibility, renewable sources should be used more frequently now that non-renewable sources have dominated the electricity supply for a while. Solar energy is the widely utilized energy source in non-conventional and solar power plants that use PV arrays to absorb this energy have grown to be crucial components of transmission networks. Harmonics are generated by the use of non-linear loads in PV systems. In these situations, filters like active or passive filters that lower the system’s harmonic content can be utilized to amplify the power quality. It is necessary to use a SAHF (Shunt Active Harmonic Filter) to eliminate or cancel the system’s undesired harmonics by supplying equal and anticlockwise phase current and compensating for reactive power. SAHF is necessary to produce equal but 180° in phase current in order to compensate for harmonics. This study uses MATLAB/SIMULINK to examine a PV-SAHF with ZSI and VSI in order to eliminate current harmonics from the system and provide reactive power compensation. ZSI is used to construct the SAHF, and it doesn’t need a separate controller to trigger it. The FFT (Fast Fourier Technique) technique is used to determine the proportion of THD for both ZSI and VSI in this paper’s system analysis of SAHF using ZSI and VSI.
