The increasing penetration of photovoltaic (PV) systems into modern power grids necessitates effective strategies to maintain grid stability during disturbances. This study investigates the optimization of grid-connected PV systems by incorporating Low-Voltage Ride-Through (LVRT) capability in conjunction with a Dynamic Static Synchronous Compensator (DSTATCOM). LVRT enables PV systems to remain connected to the grid during voltage sags, while DSTATCOM provides dynamic reactive power support, thereby enhancing voltage regulation and overall system stability. The coordinated operation of these technologies is analyzed to assess their impact on mitigating voltage fluctuations and ensuring secure power transfer under fault conditions. Simulation results demonstrate that the combined implementation of LVRT and DSTATCOM significantly improves grid stability compared to conventional PV integration without these control features. The findings highlight the importance of advanced control strategies and grid-supportive technologies for reliable and grid-friendly integration of photovoltaic systems..
