Abstract

This paper aims at the development of multilevel inverter (MLI) based unified power quality conditioner (UPQC) for power quality improvement in 13 Bus system. In this paper, a 9-level based UPQC system is developed to maintain the system voltage and current profile at the grid as well as the load. The power quality of the proposed systems is progressed by controlling the MLI switches using a firefly algorithm (FFA) based pulse width modulation (PWM) scheme. The synchronization of UPQC with proposed 13 bus system is done with same FFA algorithm. The simulation and experimental results of the proposed system are clearly presented, which indicates that proposed FFA-PWM can facilitate the seamless control, over 9-level UPQC converter when power system instability is detected and it also improves the power quality in the system within the standard limit.
