A Review of Control Techniques and Energy Storage for Inverter-Based Dynamic Voltage Restorer in Grid-Integrated Renewable Sources

Power quality (PQ) is a key issue, particularly for technologically advanced process equipment, whose performance mainly depends on the of supply. Problems with PQ such as voltage swells/sags, interruptions, and harmonics are defined by any voltage, current, or frequency abnormalities causing damage failure end-user equipment. Outages interruptions lead to malfunctioning equipment sensitive loads, diagnostic in healthcare facilities, clinics, educational institutions, detention centers, while further increasing significant economic losses. Custom power devices (CPDs) recommended enhancing quality, best most economical solution considered be dynamic restorer (DVR). Several methods suggested improve using restorer; among them, encouraging ways use multilevel inverter (MLI) restorer. This article combines latest work literature, well detailed discussion issues grid-integrated renewable energy sources (RESs), DVR principle its operating procedures, system components, storage-based topologies, control unit, converter-based topologies. In addition, synthesis storage, strategies, inverters DVR. review benefits those interested investigating relevant comprehensive reference.
