Abstract
Synchronous reference frame theory (SRFT) based on optimized Proportional Integrator (PI) controller in shunt active power filter (SAPF) is proposed to mitigate current harmonics in the presence of non-liner load system. Normally, non-linear loads such as furnaces, adjustable drives (ASDs), modern power electronics devices are responsible for producing undesirable harmonics in electrical parameters during their operation. To mitigate such unwanted harmonics in non-linear load system, (PI) controllers are effectively employed in different types of advanced techniques to diminish the presence of harmonic mechanisms in the system. In the proposed work, the two optimization algorithms such as genetic algorithm (GA) and harmony search (HS) have been effectively used for tuning (PI) controller based (SAPF). Among these metaheuristic techniques, (HS) algorithm shows the best potential in the reduction of total current harmonic distortion.
