“…STATCOM is utilized to increase EPS stability and performance since it outperforms the static var compensator in terms of performance and transient response, as presented in [24]. The layout for PQ improvement, as well as the varieties of STATCOM controllers, were discussed in [25,26]. A PID-based STATCOM was used to improve stability in grid-tied WTs but NLs were not considered in [27,28].…”

In recent modern power systems, the number of renewable energy systems (RESs) and nonlinear loads have become more prevalent. When these systems are connected to the electricity grid, they may face new difficulties and issues such as harmonics and non-standard voltage. The proposed study suggests the application of a whale optimization algorithm (WOA) based on a fractional-order proportional-integral controller (FOPIC) for unified power quality conditioner (UPQC) and STATCOM tools. These operate best with the help of their improved control system, to increase the system’s reliability and fast dynamic response, and to decrease the total harmonic distortion (THD) for enhancing the power quality (PQ). In this article, three different configurations are studied and assessed, namely: (C1) WOA-based FOPIC for UPQC, (C2) WOA-based FOPIC for STATCOM, and (C3) system without FACTS, i.e., base case, to mitigate the mentioned drawbacks. C3 is also considered as a base case to highlight the main benefits of C1 and C2 in improving the PQ by reducing the %THD of the voltage and current system and improving the systems’ voltage waveforms. With C2, voltage fluctuation is decreased by 98%, but it nearly disappears in C1 during normal conditions. Additionally, during the fault period, voltage distortion is reduced by 95% and 100% with C2 and C1, respectively. Furthermore, when comparing C1 to C2 and C3 under regular conditions, the percentage reduction in THD is remarkable. In addition, C1 eliminates the need for voltage sag, and harmonic and current harmonic detectors, and it helps to streamline the control approach and boost control precision. The modeling and simulation of the prepared system are performed by MATLAB/Simulink. Finally, it can be concluded that the acquired results are very interesting and helpful in the recovery to the steady state of wind systems and nonlinear loads, thereby increasing their grid connection capabilities.

“…STATCOM as a new type of reactive power compensation device is the most widely utilization, due to its low harmonic, quick adjusting speed, wide adjusting range and so on. It can assist in improving the power quality and LVRT ability of the wind farms [2][3][4][5], but the device is more expensive. Besides, SDBR which is placed between the wind turbine and the power grid can improve the voltage of PCC under grid fault.…”

Wind turbine with squirrel-cage induction generators is confronted with major problem for power quality and fail-safe operation at grid fault. State-of-art technique used to meet low voltage ride-through (LVRT) requirements is dynamic reactive power compensation. Meanwhile, breaking resistor and energy storage system is also helpful to LVRT performance. However, these approaches have their own limitations. A hybrid of STATCOM and series dynamic breaking resistor (SDBR) to improve LVRT performance is proposed in this paper. The positive-and negative-sequence independent control is used for STATCOM control to mitigate the voltage fluctuation, while the hysteretic control is adopted for SDBR in order to control bypass switch. A new analytical approach is proposed to quantify the STATCOM rating and SDBR resistance. Simulation results by MATLAB showed that the novel method not only significantly reduces the voltage fluctuations, but also enhances LVRT performance.
