This is the authors' abstract. We don't add key points for this paper.

This manuscript initiates the design and analysis of a doubly-fed-induction-generator (DFIG) linked to the grid, aiming to assess a wind vitality conversion configuration employing an emulated wind turbine drive system. The generator’s configuration involves integrating the d-q axes reference framework with the stator flux. Independent management of real, and imaginary power, along with the dc-bus potential at the grid, is achieved through the field-aligned regulating method. Controlling real, and Quadrature power, as well as DC-bus potential, is executed using tandem converters at distinct velocities, encompassing sub, syn, and hyper-synchronous speeds. The effectiveness of these control strategies is validated through the emulation of a variable-speed wind turbine-connected DFIG, showcasing precise control over DC voltage, reactive power, and active power.
