Abstract
Power quality issues have emerged as one of the most significant problems facing a power system, due to its diverse nature and frequent occurrence. This research introduces a Photovoltaic (PV) incorporated Unified Active Power Filter (PV-UAPF) system and its control approach for generation of decarbonized clean energy and improved Power Quality (PQ). The UAPF, combining shunt and series converter, which is utilized for compensating the current quality and voltage quality issues. Moreover, the PV system is incorporated with Switched Inductor (SI) based Boost-Luo converter at DC link, which is connected between series and shunt converters. For control the operation of converter, PI controller is employed and its parameters are refined by Modified Red Kite Optimization (MRKO) algorithm. For ensuring efficient voltage regulation and to manage the functioning of UAPF, an Artificial Neural Network (ANN) controller is incorporated on load side. To further demonstrate developed work's efficacy, it is implemented in MATLAB/Simulink and comparison is made with existing methods. The outcomes reveals that the developed system has a THD value lower than 5%, ensures the quality of power is enhanced.
