“…The total active power output fluctuation of all wind farms under wind speed is shown as shown in Fig. 4 (simulation of capacity 1530 MW in stroke electric field 1, and 2 capacity of wind field of 220 MW) [19]. In spite of the regional complementarity between the wind and electric fields, the fluctuation characteristics of the wind power output can be weakened.…”

“…One is to obtain more instantaneous energy through the control of the fan [5–15]. The other is to assist the wind farm to participate in the frequency inertia response of the system through the auxiliary energy storage system [16–20]. Morren et al [5] put forward the concept that wind turbines participate in the frequency adjustment of the system by simulating the rotational inertia characteristics of the synchronous generator.…”

“…by tracking the sub‐optimal power curve or leaving part of the power redundancy in the pitch control as the reserve power of the system's frequency inertia response. Liu et al [19] define the inertia of wind power and energy storage, and analyses the capacity demand of energy storage to assist the wind power's inertia response. Miao et al [20] propose a control method that combines the kinetic energy of the rotor of a wind turbine with energy storage to prevent the fan speed recovery from causing secondary impact on the grid frequency.…”

“…Generally, the inertia time constant of the synchronous generator is about 4 to 18 s, and the fast-frequency response lasts about 7 to 15 s [22]. Thus, we set T J as 11 s and ∆T as 11 s (average value), giving…”

With the increasing penetration of wind power generation, the frequency regulation burden on conventional synchronous generators has become heavier, as the rotor speed of doubly-fed induction generator (DFIG) is decoupled with the system frequency. As the frequency regulation capability of wind farms is an urgent appeal, the inertia control of DFIG has been studied by many researchers and the energy storage (ES) system has been installed in wind farms to respond to frequency deviation with doubly-fed induction generators (DFIGs). In view of the high allocation and maintenance cost of the ES system, the capacity allocation scheme of the ES system—especially for fast-frequency response—is proposed in this paper. The capacity allocation principle was to make the wind farm possess the same potential inertial energy as that of synchronous generators set with equal rated power. After the capacity of the ES system was defined, the coordinated control strategy of the DFIG-ES system with consideration of wind speed was proposed in order to improve the frequency nadir during fast-frequency response. The overall power reference of the DFIG-ES system was calculated on the basis of the frequency response characteristic of synchronous generators. In particular, once the power reference of DFIG was determined, a novel virtual inertia control method of DFIG was put forward to release rotational kinetic energy and produce power surge by means of continuously modifying the proportional coefficient of maximum power point tracking (MPPT) control. During the deceleration period, the power reference smoothly decreased with the rotor speed until it reached the MPPT curve, wherein the rotor speed could rapidly recover by virtue of wind power so that the secondary frequency drop could be avoided. Afterwards, a fuzzy logic controller (FLC) was designed to distribute output power between the DFIG and ES system according to the rotor speed of DFIG and S o C of ES; thus the scheme enabled the DFIG-ES system to respond to frequency deviation in most cases while preventing the secondary frequency drop and prolonging the service life of the DFIG-ES system. Finally, the test results, which were based on the simulation system on MATLAB/Simulink software, verified the effectiveness of the proposed control strategy by comparison with other control methods and verified the rationality of the designed fuzzy logic controller and proposed capacity allocation scheme of the ES system.

“…In this context, the wind turbine can provide dynamic frequency support to the active power disturbance of the power grid, and improve the inertia of the power grid with high penetration of wind power. Furthermore, in [24], it proposes that the energy storage devices can be equipped at the PCC to emulate the inertia of the wind farm. Then when the wind power generator provides dynamic frequency support, the MPPT can still be realised at the same time.…”
