“…D. Yang et al proposed a temporary frequency support scheme of DFIG that can improve the frequency nadir while ensuring rapid frequency stabilization. According to the analysis and test results, the proposed scheme performed well, particularly for high wind power penetration levels [24]. Y. Liu et al assessed the frequency response of U.S. power grid with an industry-provided full-detail interconnection model [25].…”

“…In power systems with high wind energy penetration, the unpredictable and fluctuating wind behavior can affect the frequency stability. In addition, wind turbines with doubly fed induction generator (DFIG) do not have an intrinsic inertial response and, as a consequence, their output power does not respond to changes in the system caused by the loss of generating units, increased energy demand, or microgrid operation [5,6]. The lack of inertia response of the DFIG associated with the lack of controls or systems, which allow the wind system to inject an extra active power, reduces the kinetic energy in the system.…”

This paper presents a novel methodology for frequency control of a microgrid through doubly fed induction generator (DFIG) employing battery energy storage system (BESS) and droop control. The proposed microgrid frequency control is the result of the active power injection from the droop control implemented in the grid side converter (GSC) of the DFIG, and the BESS implemented in the DC link of the back-to-back converter also in the DFIG. This methodology guarantees the battery system charge during operation of the connected DFIG in the network, and the frequency control in microgrid operation after an intentional disturbance. In order for the DFIG to provide frequency support to the microgrid, the best-performing droop gain value is selected. Afterwards its performance is evaluated individually and together with the power injected by the battery. The power used for both battery charging and frequency support is managed and processed by the GSC without affecting the normal operation of the wind system. The simulation tests are performed using Matlab/Simulink toolbox.

“…Wind power has rapidly grown during recent decades because of the concerns about CO 2 emissions and a lack of fossil fuel [1]. As conventional thermal generators are gradually replaced by converter-interfaced variable-speed wind turbine generators (WTGs), the system inertia of all online synchronous generator fleets is reduced [2]. This is because WTGs are unable to respond to the frequency change following a disturbance [3].…”

Converter-interfaced doubly-fed induction generators (DFIGs) can provide short-term frequency support (STFS) capability by releasing rotating kinetic energy. After arresting the frequency decrease, the rotor speed should return to its initial operating condition. During the rotor speed recovery process, special attention should paid to the performance of the rotor speed restoration duration and size of the second frequency drop (SFD). This paper suggests an enhanced STFS method of DFIGs to preserve better performance of the frequency nadir with less released rotating kinetic energy and accelerate the rotor speed restoration. To this end, a rotor speed-varying incremental power is proposed and is added to the maximum power tracking (MPT) operation reference during STFS, thereby releasing less rotating kinetic energy from DFIGs; afterward, the power reference smoothly decreases to the reference for MPT operation during the preset period. Test results clearly demonstrate that since even less rotating kinetic energy is utilized, the proposed method can preserve better performance of heightening the frequency nadir; furthermore, the proposed method accelerates the rotor speed restoration when the proposed strategy produces the same SFD as the conventional method, thereby improving the power grid resilience.
