Abstract:

In today's electrical system, the integration of Solar Photo Voltaic (PV) into the grid is actively promoted to address the rising demand for electrical power and mitigate environmental concerns associated with fossil fuel consumption. Power Quality (PQ) emerges as a crucial concern that impacts both utilities and consumers. The onset of PQ issues in the contemporary electric power system stems from the interconnection of PV, the adoption of grid technologies, the widespread utilization of power electronics equipment and the utilization of advanced optimization techniques to obtain maximum power from PV. This paper proposes a MOGWO controller-based PV DSTATCOM employing a PUC5 inverter to address the PQ problems, which are to obtain the maximum power from the three solar panels and minimum Total Harmonic Distortion. The voltage-source inverter's control signals are derived through the PQ control scheme. The effectiveness of the suggested system is validated through MATLAB outcomes. The results underscore the significance of the proposed MOGWO-based MPPT algorithm in enhancing performance and notable enhancements achieved in the performance of the PV-DSTATCOM, leading to simultaneous improvements in current Total Harmonic Distortion (THD), which is obtained around 3.29%.
