Stability and LVRT Enhancement of Grid-Connected Wind Generator Using FACTS-Based Dynamic Voltage Restorer
Abstract

This study focuses on using a dynamic voltage restorer (DVR) as a series compensating device to mitigate voltage sags and improve low voltage ride-through (LVRT) compliance in wind-integrated microgrids. Ensuring voltage stability while meeting LVRT requirements is challenging, as failure can lead to system instability and reduced reliability, especially during grid faults that cause sudden voltage drops. A DVR can quickly restore voltage to pre-fault levels, minimizing the impact of voltage sags and maintaining power supply during system fluctuations, allowing wind generators to operate continuously. As renewable energy integration in microgrids increases, the benefits of DVR become more apparent. A MATLAB/Simulink simulation model was used to assess DVR performance under various fault scenarios, highlighting its costeffectiveness and reliability in meeting grid standards and enhancing power quality. The results demonstrate the DVR’s capability to rapidly restore voltage, reduce voltage sags, and ensure supply stability during transitions.

Introduction

The growing use of renewable energy sources, especially wind energy, has brought about challenges concerning voltage regulation and the reliability of modern power systems.
