This paper presents a fully optimized fuzzy proportional-integral-derivative with filter (FPIDF) load frequency controller (LFC) for enhancing the performance of a hybrid microgrid system. The Marine Predator Algorithm (MPA). a recent optimization algorithm. is used to optimize the gains as well as the input scaling factors and membership functions of the proposed fuzzy PIDF controller. https://fitnessgravesyardes.shop/product-category/selector-knob/
