Analysis reveals dynamic voltage restorer improves power quality in distribution networks, indicating its viability for sensitive and non-linear loads.
The increasing presence of sensitive and non-linear loads in power distribution networks has intensified the demand for high-quality, disturbance-free electrical energy. Power quality issues such as voltage sags, swells, and harmonic distortions have become a significant concern, affecting both utility providers and end-users. Among the various custom power devices developed to address these issues, the Dynamic Voltage Restorer (DVR) stands out as a reliable and efficient solution for mitigating voltage-related disturbances. This paper explores the configuration, operation, control strategy, and simulation-based performance analysis of DVR in maintaining voltage stability. The DVR’s capability to inject compensating voltage under dynamic conditions is validated through MATLAB/Simulink-based simulations, highlighting its effectiveness in improving voltage profile and reducing harmonic distortion within acceptable limits.
