Research on frequency inertia response control strategy of SCESS-DFIG system considering variable wind speed

open access: yesThe Journal of Engineering, 2019
The doubly fed induction generator (DFIG) has insufficient capacity to respond to the frequency inertia of the power grid due to the isolation between the rotor kinetic energy and the power grid by the generator-side converter.
