Innovated Inertia Control of DFIG with Dynamic Rotor Speed Recovery

CSEE Journal of Power and Energy Systems, 2022
High wind power penetration (WPP) is challenging system frequency stability. As a countermeasure, virtual inertia controls are complemented to utilize kinetic energy (KE) stored in wind turbine generator (WTG) for frequency regulation. While without restoration, generation efficiency of WTG will be degraded after inertia contribution.

Flexible Frequency Response Strategy with Smooth Rotor Speed Recovery of a DFIG-Based Wind Turbine

Electronics (Switzerland), 2023
Grid frequency must be regulated in its nominal range to guarantee the stable operation of an electric power grid. Excessive grid frequency excursions result in load shedding, grid frequency instability, or even synchronous generator damage. With the growing wind penetration, there is an increasing issue about the reduction in inertia response.

An adaptive droop control strategy with smooth rotor speed recovery capability for type III wind turbine generators

International Journal of Electrical Power and Energy Systems, 2022
Abstract This paper presents an adaptive droop control scheme with smooth rotor speed recovery capability for doubly-fed induction generators (DFIGs, type III wind turbine generators) to improve the frequency nadir, minimize the second drop in the frequency, and regulate the time to meet the MPPT curve. To this end, an adaptive droop gain that decays
