Abstract
In recent days multilevel inverters (MI) have played an essential role in photovoltaic (PV) integrated supply systems. MI has high efficiency and is more robust compared to the traditional two-level inverter. This paper presents a modular cascaded multilevel inverters (MCMI)-based hybrid shunt active power filter (HSAPF) with PV integrated for power quality (PQ) improvement in three-phase utility systems. The main aim is to deliver the PV system's active power and reduce the current harmonics by injecting the compensation current at the point of intersection (POI). The main contributions in this work presents an optimization based approach called the predator-prey based fire-fly optimization (PPFO) for reducing the total harmonic distortions (THD) and, the Adaptive Perturb and Observe–Fuzzy (APOF) is developed for tracking the maximum power. The effectiveness of the PPFO is tested with other methods like particle swarm optimization (PSO) and fire-fly optimization (FO). The proposed technique is performed using MATLAB/ Simulink tool under different supply conditions.
