Abstract: This paper reviews the growing importance of Low Voltage Ride Through (LVRT) capabilities in modern power systems, particularly in the context of renewable energy integration. With increasing reliance on wind and solar generation, voltage sags and grid disturbances pose challenges to system stability. Dynamic Voltage Restorers (DVRs) are identified as effective tools for mitigating these voltage issues. This review discusses various DVR-based LVRT enhancement strategies, control techniques, and integration approaches with Energy Storage Systems (ESS). Optimization methods like Particle Swarm Optimization (PSO) and Whale Optimization Algorithm (WCA) are also explored for fine-tuning control parameters. The paper synthesizes findings from recent literature and concludes with future trends and research directions.
