Bidirectional converter with hybrid UPQC implementation for power quality improvement

Abstract

This paper presents a power quality enhancement strategy based on an energy storage device using the active power line cleanser in energy systems. The PQ challenges can be fixed in this framework by using the efficiency of the power compensation. For distributed generators, the transmission line is used to preserve the shunt inverter’s DC connection capacitor and dynamic voltage regulator. The renewable power source is used to provide the supply for bidirectional converter which controlled by using MPPT method. This proposed system consists of dynamic voltage restorer, bidirectional power flow converter, PV arrays, shunt inverter, shunt active power filter control, and super capacitor energy storage system. The PQ troubles of sag and swells are addressed at distribution system and achieve the compensation. The simulation designs are carried out in order to validate the proposed system topology results with their performance.
