Abstract
Voltage sag is common power quality issue that disturb load operation and need attention. The Dynamic Voltage Restorer (DVR) is an effective solution for voltage sags compensation. However, the conventional DVR, consisting of a DC source and an inverter, is utilised only during voltage sag events, which raises economic feasibility concerns. This paper introduces a novel approach that integrates the DVR with the power converter with the aim of mitigating grid voltage sags that the converter may encounter. The proposed method involves combining the DVR directly with the converter, eliminating the need for a DC source and a separate DC-AC inverter within the DVR. Such an integration provides a cost-effective and efficient solution for voltage sag mitigation. The effectiveness of the proposed approach is evaluated by simulation studies, demonstrating its reasonability and its capability to compensate for voltage sags. The results highlight the potential advantages of this integrated system in ensuring uninterrupted converter operation.
