“…Among these sources, the wind power has widespread uses worldwide. Therefore, it rapidly gained development and advanced research technologies, and this led the wind power to be strongly able to produce electricity in an adaptable and reliable way besides providing an acceptable connection with the power grid . Thus, the wind power capacity reaches more than 3 MW, and this can be referred to as advanced techniques, being applied in wind turbine design .…”

SUMMARYThis paper presents a simplified voltage control of paralleling doubly fed induction generators (DFIGs) connected to the grid by using static Var compensator (SVC). The DFIG converters are based on a voltage source converter in the grid side converter (GSC) and current source converter in the rotor side converter (RSC). The GSC is employed to work like static synchronous compensator (STATCOM) to provide precise control to maintain the DC link voltage under control. The RSC is oriented to control real and reactive powers of the DFIG. Instead of adding two SVCs in every DFIG bus it connects only one SVC in the point of common coupling of the generators to enhance the voltage stability at a steady state and dynamic operation by decreasing the reactive power hence to increase the voltage amplitude. The comprehensive simulations are carried out using PSCAD/EMTDC program. The results show that the SVC has improved voltage stability and promote the system transient response by compensating reactive power. Furthermore, this study has presented the possibility of using one SVC with low capacity based on the SVC characteristics adjusted only by choosing a suitable transformer rating. Moreover, the system model simulation was tested at steady state and dynamic mode during constant and random wind speeds. Using one SVC with low capacity leads to decrease power dissipation, and this directly reduced the power cost.

Attention has been paid by many researchers to address the various challenges of grid connection of DFIG-based Wind Energy Conversion Systems (WECS). This chapter focuses on the design of a robust H8 controller for the power flow between the stator of the Doubly-Fed Induction Generator (DFIG) and the grid. The robust H8 controller design is formulated as a mixed-sensitivity problem. A mathematical model of the DFIG written in an appropriate d-q reference frame is established to carry out simulations. The proposed power control scheme is elaborated and compared with a conventional Proportional-Integral (PI) controller based on vector control technique. The results show interesting performance of the controlled system in terms of the power reference tracking (the active and reactive power) and robustness against parameter variations compared with the conventional PI controller.
