The integration of renewable energy sources into power systems has increased significantly in recent years. Among various types of renewable energy, the use of wind energy is growing rapidly due to its low operating cost, wide distribution worldwide, and no greenhouse gas emissions. However, power systems integrated with wind energy may face stability and reliability issues due to the intermittent nature of wind power. Therefore, in power systems connected to wind farms, it is usually required to use some compensators such as static synchronous series compensator (SSSC) to increase the system performance under abnormal conditions. On the other hand, for an SSSC to be effective in improving the system performance, it must be equipped with a suitable controller. In this paper, a fuzzy logic controller (FLC) is used for the SSSC because of its advantages over conventional controllers. Extensive research has been conducted in power systems with wind turbines in which SSSC or FLC has been used; however, their simultaneous application in such systems has received less attention. Therefore, this article aims to fill this gap. The proposed method is implemented on two power systems and the simulation results are analyzed. In both systems, the dynamic behavior of three different wind farms is examined. In the first and second wind farms, either a squirrel cage induction generator (SCIG) or doubly-fed induction generator (DFIG) are used, whereas in the third one which is a combined wind farm (CWF), an equal number of SCIG and DFIG are employed. In wind farms with SCIG or DFIG, an SSSC is also utilized. Furthermore, an FLC is employed for the SSSC to improve its efficacy. A proportional integral (PI) controller is also considered for the SSSC, and its results are compared with FLC results. The simulation results confirm the superiority of FLC over PI controller.

“…1 illustrates the detailed configuration that was used for this work. In this structure, the stator windings of DFIG are directly coupled to the three-phase electric grid, whereas the rotor windings are coupled to the main mover by an AC-DC-AC converter 5 . The AC-DC-AC converter provides three-phase rotor excitation power with modifiable frequency, phase, and magnitude and guarantees that the slip power can flow on both sides.…”

In this article, an optimized design methodology is presented for a Fractional-Order Fuzzy Proportional-Derivative with Integral (FO Fuzzy PD + I) regulator using the Social Spider Optimization (SSO) technique. The research focuses on its application in the control of Doubly Fed Induction Generator (DFIG)-based wind turbine systems (WTS). The FO Fuzzy PD + I controller integrates the capabilities of the Fuzzy intelligent regulator and the Fractional-Order Proportional-Integral-Derivative (FO-PID) controller, enhancing DFIG current control while allowing independent control of active and reactive power. The approach is incorporated within the Direct Vector Control (DVC) strategy of the DFIG's rotor-side converter (RSC), replacing the conventional Proportional-Integral (PI) regulator in the internal current loops. Extensive performance evaluations are conducted under various operating conditions, including active power reference changes, parameter uncertainties, and rapid wind speed variations. Comparative analyses with SSO-optimized PID and Fuzzy regulators show the FO Fuzzy PD + I regulator performs better in terms of maximum overshoot, extreme undershoot, settling time, and Total Harmonic Distortion (THD) reduction. These findings underscore the regulator's potential for enhancing the reliability and efficiency of DFIG-based WTS. Furthermore, the adaptability of the FO Fuzzy PD + I regulator positions it as a versatile control solution with implications extending beyond the realm of wind energy, potentially benefiting various industrial sectors that demand precise and dynamic control mechanisms. As renewable energy sources continue to gain prominence in the global energy landscape, this research contributes to the broader mission of realizing a sustainable and eco-friendly energy future.

A wind turbine system (WTS) is a highly coupled and nonlinear system where the output power depends upon highly uncertain wind speed. Therefore, the quality of produced power becomes a challenging problem for researchers. Direct Vector Control (DVC) is a powerful and widely utilized power control strategy to deal with winds that vary rapidly and randomly. As a result, this article employed the newly developed Social Spider Optimization (SSO) technique to optimize the design parameters of Fractional-Order Fuzzy Proportional-Integral with Derivative (FOFPID) regulator to maintain the output power of the studied DFIG-based WTS at the rated value under dynamic wind conditions. The suggested FOFPID controller integrates the capabilities of the Fuzzy intelligent regulator and the Fractional-Order controller, enhancing DFIG current control while allowing independent control of active and reactive power. The approach is incorporated within the DVC strategy of the DFIG’s rotor-side converter (RSC), replacing the conventional Proportional-Integral (PI) regulator in the internal current loops. Extensive performance evaluations are conducted under various operating conditions, including active power reference changes, parameter uncertainties, and rapid wind speed variations. Comparative analyses with SSO-optimized PID and Fuzzy regulators show that the FOFPID regulator performs better in terms of maximum overshoot, extreme undershoot, settling time, Total Harmonic Distortion (THD), and Weighted Total Harmonic Distortion (WTHD). The suggested FOFPID regulator also displays stronger robustness against parameters mismatch and weather change than other regulator architectures.
