Investigation for Causes of Poor Power Quality in Grid Connected Wind Energy - A Review

This topic represents a technical review of Power Quality problems associated with the Renewable based wind energy system and the investigation of causes of poor power quality issues related with grid connected wind farm. Renewable Energy Source (RES) integrated at distribution level is termed as Distributed Generation(DG).The utility is concerned due to the high penetration level of wind energy in distribution systems, as it may pose a threat to network is terms of Power Quality(PQ) issues , voltage regulation and stability. Therefore the DG systems are required to comply with strict technical and regularity frameworks to ensure safe, reliable and efficient operation of overall network. Wind energy system integration issues and associated PQ problems are discussed. Integrating renewable into grids to any considerable degree can expose the system to issues that need attention lest the functionality of the grid be impaired. such issues can be voltage function, frequency deviation of power Quality.
