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.

Floating offshore wind turbines (FOWT) are subjected to strong loads, mainly due to wind and waves. These disturbances cause undesirable vibrations that affect the structure of these devices, increasing the fatigue and reducing its energy efficiency. Among others, a possible way to enhance the performance of these wind energy devices installed in deep waters is to combine them with other marine energy systems, which may, in addition, improve its stability. The purpose of this work is to analyze the effects that installing some devices on the platform of a barge-type wind turbine have on the vibrations of the structure. To do so, two passive control devices, TMD (Tuned Mass Damper), have been installed on the platform of the floating device, with different positions and orientations. TMDs are usually installed in the nacelle or in the tower, which imposes space, weight, and size hard constraints. An analysis has been carried out, using the FAST software model of the NREL-5MW FOWT. The results of the suppression rate of the tower top displacement and the platform pitch have been obtained for different locations of the structural control devices. They have been compared with the system without TMD. As a conclusion, it is possible to say that these passive devices can improve the stability of the FOWT and reduce the vibrations of the marine turbine. However, it is indispensable to carry out a previous analysis to find the optimal orientation and position of the TMDs on the platform.

“…Consequently, the economical and robust power smoothing system should be developed in place of the applications of ESS devices. Accordingly, a virtual system was widely favored by multiple engineering studies [ 43 , 44 , 45 , 46 ], and it can be built through implementation of various automated control strategies, which would ultimately regulate different operating parameters of WECSs. Recently, a dual objectives‒control technique was presented to reduce the torque ripples of the turbine shaft by implementing the frequency separation principle [ 47 , 48 ].…”
