“…SMC is fundamentally a variable structure control that offers a robust control approach with which the dynamics and operation of STATCOM interconnected wind-diesel power system can be controlled whenever disturbance in load or wind power occurs (Itkis, 1976;Mi et al, 2020). In Mi et al (2016), Thoker andLone (2021), andYunhao et al (2018), an SMC scheme is developed to control the charging and discharging operations of flexible alternating current transmission system (FACTS) and energy storage devices. Frequency regulation in a wind energy-based power system is reported in Sharma and Naresh (2019) and Kumar et al (2021) using an SMC scheme.…”

The dynamic nature of load and wind power could lead to reactive power imbalance, and hence the voltage deviations in a wind–diesel power system. These deviations, if not controlled, may drive the system to operate in an unstable manner. Therefore, in this paper, a static synchronous compensator (STATCOM) is interconnected to the system to achieve reactive power balancing and minimize voltage deviations. To improve the dynamic performance of STATCOM and achieve the effective operation of the system, an optimized sliding mode controller (SMC) is designed. With the help of the design of a first-order switching manifold, an SMC is designed, which generates a control law to control the converter firing angle, and hence the reactive power output of the STATCOM. To eliminate the chattering drawback of SMC and improve the convergence characteristics, a second-order super-twisting sliding mode controller (STSMC) is proposed. The asymptotic stability of the proposed controller is guaranteed through the Lyapunov stability analysis. Particle swarm optimization (PSO) is employed to fine-tune controller parameters and achieve optimal performance. Validation of the improved performance of the system through this proposed scheme has been carried out in the MATLAB/Simulink environment and presented in the simulation studies.

Reactive power management and voltage control are the critical problems to be dealt with in hybrid power systems, considering the frequent changes in load and wind power along with parameter uncertainties. Therefore, in this work, the load-side converter with a doubly-fed induction generator is controlled and operated as a static synchronous compensator to provide reactive power support to the system. A higher order sliding mode controller with a super-twisting feature is proposed as a robust controller for the load-side converter operation to regulate the reactive power balance and improve the voltage response of the system. The asymptotic stability of the applied control scheme is guaranteed using the Lyapunov stability analysis. MATLAB-based computer simulation studies are conducted to show the efficacy of the proposed control structure while considering the disturbances in load, wind power, and parameter uncertainties.

TKR'nin yüksek performanslı reaktif güç denetimi için birçok araştırmacı, model öngörülü denetim, bulanık mantık, yapay sinir ağları (YSA), genetik algoritma, kayan kipli denetim gibi çeşitli denetim stratejilerini önermiştir [6][7][8][9][10].

In this study, the reactive power of thyristor controlled reactor (TCR) that is fundamental element of flexible ac transmission system devices is controlled using neuro-fuzzy controller. Adaptive neuro fuzzy inference system (ANFIS) is used as neuro-fuzzy control architecture. A simulation model was developed in MATLAB / Simulink environment to examine the performance of the proposed controller. Figure A. Proposed Method for Reactive Power Control of Thyristor Controlled Reactor Purpose: Conventional Proportional Integral (PI) controller is mostly used flexible AC transmission system (FACTS) devices. However, system parameter variations and non-linear system structures severely impair the performance of this controller. In this study, the neuro-fuzzy controller is used for overcome to these disadvantages. Theory and Methods: The neuro-fuzzy controller is designed for reactive power control of TCR. Adaptive neuro-fuzzy inference system (ANFIS) is used as neuro-fuzzy control architecture. In order to examine the performance of the proposed controller, two different cases are simulated in the studies. The reactive power control performance of the proposed controller is compared to two PI controllers. Results: Simulation results show that the tracking of the reference reactive power of proposed controller is more successfully than to PI controllers. The results that are obtained under the voltage disturbance condition show that, the neuro-fuzzy controller is better disturbance rejection capability than PI controllers. Conclusion: In this study, the neuro-fuzzy controller is used for reactive power control of TCR. The proposed controller for TCR is more superior than conventional PI controllers in terms of control performance parameters (rising time, settling time and overshoot) values. The proposed controller has improved the reactive power control capabilities of thyristor controlled reactor.
