Improvement of LVRT Capability Using PSS for Grid Connected DFIG Based Wind Energy Conversion System

This paper mainly aims to investigate the FRT capabilities of a wind power plant connected to the grid. The study introduces an overview of different approaches used to increase Ride-Through (FRT) fault capability in transient WTs based on DFIGs. This paper provides a comprehensive review of the various strategies employed to define the competencies of DFIG WT-based systems with low-voltage travel (LVRT) (WT). The main DFIG-based type-III WT machine is connected to the grid without a digital power interface as the world uses approximately 20-25% of renewable wind energy; consequently, it cannot manage terminal voltage or a reactive electrical output. Unique LVRT approaches were therefore proposed within this document based upon the implementation of other active interface technologies. Today, many techniques to overcome this low-voltage problem by failure are being developed. This article tries to establish these active methods to reduce the gap in overall adaptive performance, controller operational complexity, and economic efficiency by presenting a complete analysis of LVRT strategies for DFIG-based WECS. It also highlights the methods to increase the capacity of LVRT by applying a PSS to configure the relationship in 3 significant areas based on its grid inclusion. FACT device connections are also used in WECS to investigate its efficiency and advantages, including PSS.
