|Abstract:||This paper proposes a photovoltaic (PV) and battery interfaced series hybrid active power filter (SHAPF), which consists of series active power filter and an LC shunt passive filter. The main benefits of the proposed system provide the compensation against the voltage harmonics, current harmonics and voltage interruption for the whole day. A series active power filter (SAPF) demands a source of energy for compensating the voltage sag/swell. The proposed topology utilizes the green energy source with an energy storage unit to meet the DC-link voltage requirement of the SAPF. The control strategy is based on the dual formulation of the compensation system principles with adaptive fuzzy logic controller (AFLC). In addition the new coordination logic control is proposed to provide the continuous harmonics compensation and outage compensation at the different conditions. The simulation and experimental studies are carried out to validate the effectiveness of the proposed PV interfaced three-phase four-wire SHAPF.|
