The proposed system employs state-of-the-art optimization and control strategies to tackle the challenges posed by grid disturbances. A thorough examination is conducted into how power dips and grid outages impact the efficiency of the DFIG-based WECS. The intelligent optimized controller significantly outperforms traditional control methods in shielding DFIG-based WECS from low voltage occurrences. As a consequence of this work, which contributes to ongoing efforts to enhance the grid integration capabilities of wind energy systems, renewable energy output may become more stable and reliable. It is necessary to ensure that the wind energy systems are operated in accordance with the grid code. It is expected that the active power control with frequency regulation capabilities, the inertia control, and the reactive power control with voltage regulation capability will all be met under typical operating circumstances. Because of the existence of PEC, the inertia of the generator is separated from that of the grid. It is necessary for the WECS to have virtual inertia in order for it to participate in the frequency support by boosting the power at the precise moment when it is required. The wind turbines are deloaded from the MPP, which results in the creation of a margin for the frequency control. This allows for the achievement of the goal. In order to achieve deloading, either the pitch angle or the generator speed may be controlled. Deloading wind turbines using variable droop technology is one method that may be used to accomplish primary frequency adjustment. The provision of low voltage ride-through (LVRT) and high voltage ride-through is required during the operation of the fault circumstances.
