“…However, the deployment of the variable-speed wind turbines can smooth 75% of the voltage fluctuations produced by fixedspeed turbines [50], [53]. One of the main problems of this technology is its inability to meet the requirements of the network (grid codes) as it does not depend on the power electronics to connect with the network, which in turn are responsible for the control of reactive power and terminal voltage [54].…”

The strengthening of electric energy security and the reduction of greenhouse gas emissions have gained enormous momentum in previous decades. The integration of large-scale intermittent renewable energy resources (RER) like wind energy into the existing electricity grids has increased significantly in the last decade. However, this integration poses many operational and control challenges that hamper the reliable and stable operation of the grids. This article aims to review the reported challenges caused by the integration of wind energy and the proposed solutions methodologies. Among the various challenges, the generation uncertainty, power quality issues, angular and voltage stability, reactive power support, and fault ride-through capability are reviewed and discussed. Besides, socioeconomic, environmental, and electricity market challenges due to the grid integration of wind power are also investigated. Many of the solutions used and proposed to mitigate the impact of these challenges, such as energy storage systems, wind energy policy, and grid codes, are also reviewed and discussed. This paper will assist the enthusiastic readers in seeing the full picture of wind energy integration challenges. It also puts in the hands of policymakers all aspects of the challenges so that they can adopt sustainable policies that support and overcome the difficulties facing the integration of wind energy into electricity grids.

“…Regulation or politics have not yet launched a repowering initiative. It is economically viable to replace older wind turbines in particular markets, even if they can last for many more years [22]. In addition, repowering enables the most advanced turbines in places with the best onshore wind resources.…”

Wind turbines (WTs) create electricity by utilizing the energy of the wind. As a result, wind turbine control and cost-effective operation were studied. The control system offers a long service life, maximum energy output, and safety. On control methods and control strategies, various ways for limiting and optimizing energy consumption were discussed. Integration of wind power may compromise the stability of the transient system. Asynchronous induction generators cannot handle the quantity of reactive power generated in wind energy applications. WTs are usually constructed to withstand inclement weather but not for high speeds or torque. Strong aerodynamic torques or rotational speeds are capable of destroying WT blades. To prevent this, WTs always have a cutout speed over which the turbine will be stopped by its brakes. When excessive wind speeds endanger the safety of the turbines, the WT employs a range of control techniques. As a result, all WTs are constructed using a power control method. This can regulate pitch and stall. Passive or active stall control can be applied to the WT. Therefore, this study analyzed the associated technologies, the maintenance of wind turbines, the cost, the many types of wind turbine controllers, and the negative effects and roadblocks unique to the wind energy industry.

“…On the other hand, the wind turbine (WT) system has been classified into two types of topologies: fixed speed wind turbine [5] and variable speed wind turbine (VSWT) [6]. The fixed speed WT operates at a finite wind speed limit, and it requires a multistage gearbox for increasing the generator speed, while VSWT operates at different wind speeds so that maximum output power can be achieved at several wind speeds (see for more details [7,8]).…”

This study presents the coupling memory sampled-data control (CMSDC) design for the Takagi-Sugeno (T-S) fuzzy system that solves the stabilization issue of a surface-mounted permanent magnet synchronous generator (PMSG)-based wind energy conversion system (WECS). A fuzzy CMSDC scheme that includes the sampled-data control (SDC) and memory sampled-data control (MSDC) is designed by employing a Bernoulli distribution order. Meanwhile, the membership function-dependent (MFD) H∞ performance index is presented, mitigating the continuous-time fuzzy system's disturbances. Then, by using Lyapunov-Krasovski functional with MFD $H_\infty$ performance index, data of sampling pattern and a constant signal transmission delay, sufficient conditions are derived. These sufficient conditions are linear matrix inequalities (LMIs), ensuring the global asymptotic stability of PMSG-based WECS under the designed control technique. Besides, the proposed method is demonstrated by a numerical simulation implemented on the PMSG-based WECS. Finally, Rossler's system demonstrates the effectiveness and superiority of the proposed method.
