ABSTRACT: This paper discusses how to improve power quality for effective power transfer in a grid-integrated wind energy system. The system is a wind energy conversion system based on a renewable energy farm. The system is subjected to frequent disruptions in AC loads and renewable farm power output. As a result, there is a reactive power mismatch, which causes voltage instability and power quality issues. This gap can be closed by using a variable reactive power source, such as a static synchronous compensator. Three case scenarios of the system are tested to compare their dynamic and transient performances: (A) standalone mode, (B) grid-integrated without STATCOM mode, and (C) grid-integrated with STATCOM mode. The result will be based on the fault created on the wind system, which will be classified and controlled by STATCOM.
