The power system is facing numerous issues when the distributed generation is added to the existing system. The existing power system has not been planned with flawless power quality control. These restrictions in the power transmission generation system are compensated by the use of devices such as the Static Synchronous Compensator (STATCOM), the Unified Power Quality Conditioner (UPQC) series/shunt compensators, etc. In this work, UPQC’s plan with the joint activity of photovoltaic (PV) exhibits is proposed. The proposed system is made out of series and shunt regulators and PV. A boost converter connects the DC link to the PV source, allowing it to compensate for voltage sags, swells, voltage interferences, harmonics, and reactive power issues. In this paper, the features of a seven-level Cascaded H-Bridge Multi-Level idea are applied to shunt and series active filter changeovers to reduce Total Harmonic Distortion and compensate for voltage issues. Despite its power quality capacity for common coupling, the proposed system can inject the grid’s dynamic power. During voltage interference, it can also provide a piece of delicate burden power. The simulation is carried out with the help of MATLAB/SIMULINK programming, and the results are compared to those of other conventional methods.
