Enhancing Electrical Grid Stability through Power Quality Optimization via PV-PO-UPQC: An Integrated Approach

This paper presents the results of an integrated approach aimed at enhancing the stability of electrical grids by optimizing power quality through the utilization of a PV-PO-UPQC system. The integration of photovoltaic (PV) panels, Perturb and Observe (PO) maximum power point tracking (MPPT), and Unified Power Quality Conditioner (UPQC) technology is examined for its effectiveness in mitigating power quality issues and ensuring robust grid operation. Simulation results demonstrate a reduction in voltage distribution issues (such as voltage sag, swell, dips, and short circuits) at the source side. In addition, the system demonstrates a reduction in harmonics under nonlinear load conditions, further confirming its adaptability to varying load conditions. These findings underscore the efficacy of the integrated PV-PO-UPQC approach in enhancing grid stability and reliability.
