“…For taking the full benefits of the series compensation and keeping the system stable at the same time, the researchers have proposed using a flexible AC transmission system (FACTS) series compensation or adding a supplementary damping controller (SDC) to the DFIG-converter controllers [2], [11], [12], [13]. It should be noted that the series FACTS has already been installed in many stations around the world for power-flow control and power oscillation damping [14], [15].…”

Although using a series compensation technique in a long transmission line effectively increases the transmittable power; it may cause a sub-synchronous resonance (SSR) phenomenon. Gatecontrolled series capacitor (GCSC) is an effective method for SSR damping by controlling the turn-off angle. In the previous studies, a constant supplementary damping controller (SDC) was used for controlling the turnoff angle, which can mitigate the SSR phenomenon. However, these methods can not capture the maximum transmittable power at different operating points. In this paper, a fuzzy logic controller (FLC) is proposed to compute the gain of SDC based on the wind speed and the error between the measured and reference line currents for transferring as much power as possible and damping the SSR phenomenon simultaneously. Using the MATLAB/SIMULINK program, the proposed method is tested at different operating points to validate its effectiveness and robustness. Compared to the traditional method (constant SDC), the maximum transmittable power, as well as SSR damping, is achieved in all studied cases by the proposed method (variable SDC).

“…The generated wind power decreased from 219.5 to 74.5 MW, causing a loss of 66% of the initial output. Damping methods aim to transfer as much as power possible and keep the system stable at the same time by adding a supplementary damping controller (SDC) to the DFIG converter controllers [6][7][8], replacing the PI controllers with other controllers [9][10][11][12], or inserting flexible AC transmission systems (FACTS) into the transmission line [13][14][15][16][17][18]. The supplementary damping controller (SDC) is the most prevalent method because of its low cost, effectiveness, and simplicity.…”

The interaction between the wind farm and the series‐compensated transmission line may lead to the sub‐synchronous oscillation (SSO) phenomenon which affects the system stability and equipment safety. Among the presented methods for damping the SSO phenomenon, the supplementary damping controller (SDC) is the most prevalent method because of its low cost, effectiveness, and simplicity. In all previous studies, one input control signal is fed to the SDC for mitigating the SSO. Here, two input control signals (active power and reactive power deviation) are applied to the SDC for enhancing the system stability and damping the SSO quickly. The ability of the proposed method for damping the SSO has not been investigated before. The proposed SDC is embedded into the q‐axis of the rotor‐side converter (RSC) inner current loop. The modified IEEE first benchmark model (FBM) is used to analyze the performance of the proposed method under different compensation levels, variable wind speeds, and sub‐synchronous control interaction (SSCI). Small‐signal stability using the eigenvalue approach is carried out, where the impact of the proposed method on sub‐synchronous mode, and super‐synchronous mode is investigated. The results successfully prove the superiority of the proposed method for damping the SSO under various operating conditions compared to some previous methods, where the least overshoot and faster convergence have been achieved by the proposed method in all studied cases.

“…On the basis of the previous works, the SSR phenomenon can be damped by adding a supplemental damping controller (SDC) to the doubly fed induction generator (DFIG) controller or using a flexible AC transmission system (FACTS) [3,7]. Gate-controlled series capacitor (GCSC) is widely used among the series FACTS devices because it is flexible, cheap, and simple [7,[9][10][11]. In reference [12], the SSR phenomenon was damped by GCSC.…”

Series‐compensated transmission lines can lead to a sub‐synchronous resonance (SSR) phenomenon at high compensation levels, where the system lacks stability. Gate‐controlled series capacitor (GCSC) is widely used to damp the SSR. Here, an effective and new methodology for damping the SSR is presented. The proposed method aims to alleviate the SSR phenomenon based on estimating both the frequency and the maximum value of the voltage magnitude signal rather than using the Proportional Integral controller. The appropriate turn‐off angle corresponding to the maximum value of the voltage magnitude signal is applied to the GCSC on the condition that the estimated frequency of the voltage magnitude signal is within the range of the SSR frequency. If the estimated frequency of the voltage magnitude signal is out of the range of the SSR frequency, the steady‐state turn‐off angle (1130) is applied to the GCSC. The capability of the proposed method for damping the SSR under various compensation levels, various wind speeds, and sub‐synchronous control interaction (SSCI) is validated by time‐domain simulation and eigenvalue analysis. Compared to the presented latest method for SSR damping using GCSC, all the obtained results demonstrate that the oscillations converge faster when the proposed method is activated.
