This paper deals with the smart grid integration of a photovoltaic system. The ability of a solar system to inject grid power can be managed using a variety of techniques. This makes the system work effectively and safely, maintaining the power levels within the required limits. In our work, we integrated the inverter control with maximum power point tracking using fuzzy logic control (FLC). By managing reactive power, the inverter maintains the power factor. Although the hysteresis current control is a useful technique, it has its limitations, particularly when it comes to frequency control. In this study, a modulated hysteresis control (MHC) was applied, to ensure that the inverter ran at a constant switching frequency, enhancing the efficiency of the system. The study was done using the Matlab software, and the findings demonstrated that the studied system supplied low-harmonic energy to a utility grid.
