| Summary: | Abstract Grid-tied solar photovoltaic systems use a PWM-VSI STATCOM to regulate active and reactive power. Due to high reactive power demand, often it has been experienced that there is a decay in reactive power supply which may cause malfunction in the load side equipments. The STATCOM balances power variations caused by solar irradiation and ensures constant DC bus voltage for efficient power conversion and optimal MPPT performance. It also provides dynamic reactive power support, balancing imbalanced loads and filtering harmonics. The modified PWM-VSI controlled by Genetic Algorithm optimized Fractional Order based STATCOM approach enhances dynamic response, improves system efficiency, and integrates with MPPT (SAR) for simultaneous reactive power compensation and extraction. The proposed system ensures grid stability during variable solar generation and outperforms the P&O MPPT controller in active and reactive power management. The proposed system uses a modified PWM-VSI STATCOM controller (FOSTATCOM) to regulate PV system voltage and current waveforms, ensuring grid stability during variable solar generation. The SAR MPPT connected SPV system tied utility grid also outperforms the P&O MPPT controller in active and reactive power management, allowing for 109.1 KW active power supply and 360.2 VAR reactive power supply by integrating modified STATCOM as compared to the P&O MPPT controller with standard PWM-VSI STATCOM which is supplying 108.1 KW and 865.3 VAR. |
