Control Hybrid Filter To Improve Power Quality In Polluted Distribution System Using interval type-2 fuzzy logic

The growth of nonlinear load became a massive issue that might affect the system’s stability. This research study will focus on an enhanced current technique that employs a fuzzy interface in conjunction with a HSAPF (Hybrid Shunt Active Power Filter and is applied to a non-linear load. The use of fuzzy logic control overcomes the challenging problem of controller parameter tuning and proves the system’s stability using Clarke’s stability definition. A hybrid filter, which is a mix of active and passive filters, is used to make the whole system cost-effective. In terms of source current harmonics, it is discovered that the these above filter actually works significantly. Finally, a comparison of two other techniques, such as a hybrid filter with interval type-2 fuzzy logic and a hybrid filter, is conducted, with the latter configuration outperforming the typical active power filter. In IEEE std-519-1992, the identical model was simulated with both perfect and distorted supply conditions, and it was discovered that the latter arrangement produces better results than the former.
