“…Various software and hardware solutions have been used for improved and efficient operation of the grid-connected WGs. The software schemes include PI-optimization methods, FLC and its modifications, and neural networks (NNs) [9,10]. Complex nonlinear troubles can be solved using some heuristic methods with minimal computational time but with poor accuracy solutions [11,12].…”

In recent times, various types of wind generators have been linked to the power grids globally and the focus has been to control them to be more efficient and reliable. This study concisely discusses performance analysis, modeling, and assessment of different wind generators (permanent magnet synchronous generator, doubly-fed induction generator, squirrel cage induction generator), covering their benefits, drawbacks, and impact on the electric power systems. This comparison aims to guarantee that their technical and economic evaluations are comparable, allowing engineers to make a more informed decision about which generator is best suitable for their installation. Findings for the investigated wind generators lead to significant observations about their application fields, such as permanent magnet synchronous generator outperforms doubly-fed induction generator and squirrel cage induction generator, especially during grid disruptions; on the other hand, squirrel cage induction generator is simple and inexpensive.

“…Unlike wind-powered DFIGs, PMSGs with a full-scale power converter are gaining popularity due to a variety of advantages, including high energy density, easy control technique, low maintenance price, and self-excitation system (Mahmoud et al, 2020b; Rahimi, 2017). Other advantages of PMSGs include total decoupling from the grid, full controllability for optimal wind energy harvesting, high efficiency, easy implementation, higher reliability, a wider range of operating, and enhanced fault ride-through (FRT) capability (Mahmoud, 2019; Parmar, 2019). Meghni et al (2020) and Wang et al (2013), list and clarify the benefits and drawbacks of various wind generators.…”

Scholars are motivated to work in the field of renewable energy systems (RESs) especially on grid-connected wind generators because of the exciting and noticeable developments going on in this area. This progress is utilized to obtain the maximal, efficient, and stable electric power from the RESs and integrating it into existing systems to improve its efficiency, stability, reliability, and overall power quality. Recently, permanent magnet synchronous generators (PMSGs) have become the main pillar of advanced wind systems thanks to their fascinating pluses over other types of wind generators. This paper presents the up-to-date trends in converter topologies, control approaches, maximal power production methods, and grid integration issues for PMSG-based wind systems. The performed statistical analyses assure the dominance of the two-level back-to-back converter among the studied power converter topologies, field-oriented control method for the machine side converter, voltage oriented control method for the grid side converter control, perturb and observe algorithm amongst the studied maximum power point techniques, and fault ride-through capability out of grid integration issues. Further, recent general trends in technological advancements for PMSG wind system components are illustrated as a pie chart in terms of percentage figures. It is expected that the researchers working in this field would benefit from this article in terms of the presented state-of-the-art statistical analyses and its related literature given in this study.

“…SVPWM relies on the space vector distribution of a typical converter, and a specific reference voltage vector is synthesized by two active voltage vectors and one zero vector. The time values related to these three vectors are calculated and distributed according to some preferred time sequencing diagrams [13], [14]. Considering these time values for six sectors, a modified modulating signal is obtained and compared with a triangular carrier signal to get the switching pulses for all switches in a converter.…”

Memory, speed, reliability, and efficiency are the main characteristics of concern in new contemporary control techniques of electric power converters. Space vector pulse width modulation (SVPWM) is a widespread digital compute-intensive control technique used in the control of power converters. This study aims to overcome the large number of calculations needed by the SVPWM algorithm, which limits its implementation in many advanced industrial applications. This paper presents a low-cost software implemented simplified SVPWM technique. The proposed strategy generates the inverter switching times in a straightforward manner with no need for complicated and time-consuming sector identification and look-up switching tables. A simulation study has been done using MATLAB/SIMULINK environment for the three-phase voltage source converter (VSC). The results in terms of total harmonic distortion (THD) in the converter line voltage are compared for the proposed technique, conventional SVPWM, and space pulse width modulation (SPWM). The execution time is reduced considerably with a slight increase in the value of THD and about 14.4 percent DC-link voltage utilization over the SPWM.
