AGC, BSA, Cascade controllers, STPPS, AVRAbstract
This study marks the first effort to optimize controller parameters for Automatic Generation Control (AGC) using the Bird Swarm Optimization (BSA) algorithm, a novel metaheuristic technique. A secondary cascade controller, TI-TID, is introduced for a two-area AGC system. Simulation outcomes reveal that the TI-TID controller surpasses conventional PI and PID controllers by achieving better settling time, peak overshoot, and peak undershoot. The integration of Solar Thermal Power Plant Systems (STPPS) and a High Voltage Direct Current (HVDC) link significantly improves system dynamics. Furthermore, a sensitivity analysis under different loading conditions confirms the sturdiness of the projected controller, which consistently maintains stable dynamic behavior despite variations in load. Further, studies with automatic voltage regulator (AVR) loops over AGC reveal improved dynamics.
