Optimizing wind energy microgrids with high-speed SRG and hybrid PI controller integration

In this system, the wind turbine generates mechanical torque, which drives the Switched Reluctance Generator (SRG) to produce electrical power. The generated AC output is then rectified into DC, which serves as the input source for grid integration through the Voltage Source Inverter (VSI). To control SRG speed, the PI controller is used by adjusting ((n + 1) Semiconductor and (n + 1) Diode Topology based Bridge Resonant (BR) converter. The Fire Fly Algorithm and Crow Search Algorithm (FFA-CSA) optimized PI controller contributes an important role in the conversion of AC output into DC voltage. The rectifier uses Pulse Width Modulation (PWM) to ensure smooth and continuous connection with the grid. The single-phase VSI ( 1 Φ VSI), PWM generator and PI controller ensures grid connection with stability and reliability. The MATLAB simulation results exhibit the outcomes such as dynamic response, power quality and system stability with THD of about 2.12% and a settling time of 0.15 s.
