The main cause for concern is power quality (PQ) problems, specifically voltage disturbances, fluctuation, sag, harmonics, and swell in the power distribution system. To correct these voltage disturbances in the electrical power distribution system, an efficient device called a dynamic voltage restorer (DVR) is integrated between the source and the load. In this study, DVR is integrated with the source to protect the sensitive load from voltage disturbances caused by the source side under non-linear load conditions. In addition, a unique Z-type source inverter (ZSI) is introduced to improve the restoration of the voltage property of DVR. This ZSI ensures that the direct current (DC) link used for the compensation process maintains a constant DC voltage. By adjusting the gain parameters of the proportional–integral–derivative (PID) controller and accounting for voltage problems such as sag, fluctuation, swell, and interruption in the load side, the hybrid Harris hawks optimization (HHO) and black widow optimization (BWO) are also utilized to regulate the Z-source DVR (Z-DVR). The 2020Ra version of MATLAB/Simulink is used to implement this proposed work and analyze the outcomes. HHO–BWO is also compared to earlier works like BWO–PID, HHO–PID, genetic algorithm–PID, and mm-sized resistance-typed sensor film controller to demonstrate its superiority in terms of total harmonic distribution and problem-solving.
