Abstract

Doubly-fed induction generator (DFIG) is too sensitive to the terminal voltage reduction. Thus, it is essential to choose an appropriate controller for converters in order to have stable voltage as well. In this article, double-fed wind turbines is controlled by vector proportional integrated regulator. For this purpose, a test network using vector proportional integrated (VPI) regulator is applied. Therefore, the stability is examined by evaluating the considered grid under different fault conditions. In addition, the performance of this grid is evaluated in the case of adding DFIG. Next, the effect of VPI regulator is analyzed on performance of this grid. The results showed that application of vector proportional integrated regulator improves grid stability to a further degree than direct vector regulator.
