Voltage Profile Improvement of Grid-Connected Wind Energy System Using STATCOM Compared with SVC by Limiting Voltage Flicker

Abstract

Aim: The research's primary goal is to improve voltage profiles in grid-connected wind energy systems. The comparative analysis on voltage profile minimization in the Grid-connected based Wind Energy Conversion System (GCWECS) is done by using voltage profile techniques such as Innovative Static Synchronous Compensator (STATCOM) and compared with Static Var Compensator (SVC). Materials and Methods: The intrusion of STATCOM and SVC in GCWECS is defined with each system possessing seven sample values and a G power is implemented to analyze the efficiency. Parameters considered are CI, alpha. The significance value is determined as 0.041 (p<0.05, statistically significant) based on SPSS analysis. Results: From observation, it is evident that the STATCOM controller 0.33% based WECS has a minimum voltage loss than the SVC 0.23%. Conclusion: The voltage profile based grid-connected wind energy system using a voltage profile technique named as STATCOM provides better voltage profile improvement when compared to SVC for the selected data.
