Abstract

Besides power decoupled control, soft and fast synchronization is an important issue because it enables the DFIG to be connected to the grid with minimum impact on the WECS and the grid [135].

Abstract

However, wind energy conversion system (WECS) is usually located in rural areas with weak grid connection, in which grid voltage unbalance may arise even during normal operation. The unbalanced grid voltage may be caused by unbalanced transmission line impedance, three-phase unbalanced load, and single-phase high-power load. Hence, the strategies to improve the performance of DFIGs under unbalanced network conditions have obtained a worldwide concern.

Abstract

The Doubly Fed induction generator (DFIG) is a popular wind turbine system due to its high energy efficiency, reduced mechanical stress on the wind turbine, and relatively low power rating of the connected power electronics converter of low costs [126].

Abstract

In view of the analysis and investigations presented, one can draw the following main conclusions: The phase angle between grid voltage and current waveforms is changed from leading to lagging within one cycle for step change in reactive component of grid current reference \( i_{\text{gq}}^{*} \). This confirms that, the capability of the GSC control to regulate the grid received reactive power for controlling the system power factor.
