The model consists of two 165 mm impulse turbines each individually coupled to 375 W grid connected induction machines.
This paper proposes a control scheme of a grid-connected doubly-fed induction generator (DFIG) wind turbine with series grid-side converter (SGSC) to improve the control and operation performance of DFIG system during network unbalance.
This ensures the safeguarding of grid connected doubly fed induction generators from the harmful effects of harmonics.
In power industry, improvement of the short circuit Fault-ride through (FRT) capability of grid integrated Doubly Fed Induction Generators (DFIGs) for the wind power system is an important issue.
In this paper, a grid-connected Doubly Fed Induction Generator controlled by a Sliding Mode Controller (SMC) is used to maximize the Wind Energy Conversion System (WECS) output power.
This paper proposes a novel direct torque and reactive power control (DTC) for grid-connected doubly fed induction generators (DFIGs) in the wind power generation applications.
A novel current-based direct power control (CB-DPC) strategy for a grid-connected doubly-fed induction generator (DFIG) is proposed.
Thereafter, Dragosavac et al. have proposed practical implementation of coordinated control, and Qiqi et al. have investigated the power angle control in case of grid-connected doubly fed induction generator wind turbines for fault ride-through, while Chaudhuri et al. have addressed system frequency support via multi-terminal direct current grids [26, 27, 28].
Many modern wind generators have power electronic systems as grid interfaces, such as doubly-fed induction generators (DFIG) or full rate power electronic interfaced induction generators and synchronous generators.
In the condition of connecting large scale doubly-fed induction generators (DFIGs) into weak grid, the closely coupled interactions between wind generators and power grid becomes more severe.
