To deliver power to the load side, the harmonics present in the system must be reduced because they have a significant negative impact on the system's power quality and dependability. A passive filter was previously used to lessen the effects of harmonics and increase the overall reliability of the system. The conservative power theory explained why harmonics were present and how they came to be there. However, it is clear from the analysis of the earlier results that the system can still use some improvement. This work suggested a hybrid shunt active power filter for achieving this goal, along with fuzzy set theory to reduce harmonics and enhance the system's power quality.
