“…The main work of this paper is to alleviate power quality matters in the distribution network by the proposed 9s UPQC topology. Different control schemes have been introduced for generation of gate signals for the inverter switches [3,13,[23][24][25][26][27][28]. These switches are controlled rectifiers controlled by gate signals which are generated by hysteresis or SPWM generator.…”

In this paper, nine switches UPQC topology with different control techniques have been depicted and compared their performances to accomplish clear inspection of the best control techniques. As conventional UPQC having twelve switches of six legs enhances the switching losses, circuit complication, costly etc. Hence nine switches UPQC topology is intended to reduce the switching losses, complexity, size and cost. This proposed topology has only three legs with three switches in each leg making total number of nine switches. The three control techniques such as Unit vector template, PQ theory and Synchronous reference frame theory have been employed in the nine switch UPQC topology. The simulation has been carried out separately for each control technique in MATLAB/SIMPOWER environment and results have been verified for higher efficiency of nine switch UPQC topology. The comparative THD of source currents and load voltages under these control techniques have been analysed. The obtained THD values are below 5% as per IEEE-519 standard.

To satisfy the expanding usage of power electronics in grid-integrated applications, an unified power quality conditioner (UPQC) is regarded as an effective power tool contributing to power quality issues. Voltage interruption problems remain unresolved even if UPQC handles current harmonics and voltage sag/swell. This study proposes a solar energy-based UPQC to export active power to the grid. The suggested method utilizes photovoltaic (PV) power for power quality management and a boost converter to send the remaining active power back into the grid. The PV-UPQC configuration’s operation is simulated using MATLAB/Simulink. The PV-UPQC system can compensate for resultant harmonics, correct voltage sags, swells, and the maintenance of load voltage at its nominal value in addition to actively supplying the power grid. A considerable decline is observed in the THD of the load current from 104.66% to 2.56%. Conversely, a 97.55% decrease in load current THD is achieved.
