Wind Energy Conversation Systems (WECS) that use a Doubly Fed Induction Generator (DFIG) aim to provide high efficiency control techniques. Future energy demands around the world will be mostly satisfied by RES. The Proportional-Integral (PI) controller tuned for power direct control of power scheme DFIG WECS is presented in this work with an intelligent metaheuristics-based design approach. Under non-smooth and nonlinear operational constrictions, gains adjustment of PI controller is represented as an optimization problem with constraints. The proposed Grey Wolf Optimizer (GWO) algorithm effectively resolves such a specified tuning problem. For reactive/actual power and DC-link voltage, the suggested GWO algorithm has the ability to execute out multiple required operational features of DFIG sequentially. The PI controller's parameters are optimized using GWO algorithm technique. Deployment of PI controller improves the operation of a Three-Phase Voltage Source Inverter (3φVSI) linked to grid. Pulse Width Modulation (PWM) rectifier, which plays a role in WECS employing DFIG, converts AC to DC with the help of a PI controller. Grid is synchronized using D-Q theory which in turn reduces steady state error. Results from hardware implementation demonstrates the effectiveness of suggested control methodology. Finally, the proposed control approach is evaluated using hardware findings from the DSPIC30F4011 microcontroller to verify proposed controls and the outcomes demonstrates that proposed control system's capabilities in monitoring and controlling under various scenarios is effective. © 2024 Elsevier B.V., All rights reserved.
