Abstract

This paper presents the design and simulation of a PV‑ integrated Unified Power Quality Conditioner (UPQC) for improving power quality in distribution networks. The Conventional UPQC systems are effective in mitigating harmonics, voltage sags and swells, and reactive power problems, but they depends on grid power to maintain the DC link voltage and current, which limits efficiency and sustainability. To overcome this limitations, the proposed system integrating photovoltaic (PV) generation with battery storage system, to reduce grid dependency and enhancing reliability.

A DC‑DC converter with Perturb and Observe (P&O) MPPT control method is used to maximize energy extraction from the PV source, meanwhile the battery ensures the stable DC link voltage during low irradiance or nighttime conditions. The shunt inverter (STATCOM mode) which compensates harmonics and reactive power using Synchronous Reference Frame (SRF) theory, and the series inverter (DVR mode) which injects compensating voltage to regulate supply and protect sensitive loads from disturbances.

The Simulation carried out in MATLAB/Simulink validate the effectiveness of the proposed configuration under varying load and irradiance conditions. Results shows reduced Total Harmonic Distortion (THD), improved voltage regulation, power factor balanced to unity, and minimized dependency on grid power. These outcomes establish the PV‑ integrated UPQC as a reliable and sustainable solution for sensitive loads in modern distribution systems, while also opening avenues for future research in AI‑based controllers, hybrid renewable integration, and smart grid applications.
