Power quality issues are a serious concern due to integrating renewable energy sources into the power grid, often resulting in costly consequences like line disruptions or sensitive load interruptions. Therefore, having a steady voltage with acceptable quality is essential. Dynamic Voltage Restorers (DVR) is a promising solution for resolving power quality issues. Even in the event of grid voltage disturbances, DVR has the ability to restore the voltage on the load side. This research presents a transformerless inverter-based DVR configuration integrated with solar system for a medium voltage power grid and controlled by proportional-integral. The recently developed metaheuristic optimization method namely the Modified Marine Predator Algorithm has been proposed to optimize the gains of the PI controller. DVR reference voltages are computed using a d-q synchronous reference frame-based approach. Simulation results are provided to verify the functionality of the proposed DVR circuit, and the controller's resilience and sensitivity to various situations such as voltage sag, voltage swell and faults are confirmed. The system's THD is compared against various optimization methods, and the results are displayed in time-domain simulations using MATLAB/SIMULINK. The proposed DVR controller successfully maintains the load voltage during sag and swell, with deviation of 0.3 and 0.28% from the reference voltage and THD is reported as 1.10 and 1.29% respectively within the IEEE limits.
