Automatic Generation Control of Multi-area Power System with UPFC using Grey Wolf Optimized PID Controller

building electrification
This paper proposes GWO based Proportional Integral Derivative (PID) controller for Automatic Generation Control in Multi-area power system with UPFC. The performance of the Particle Swarm Optimization (PSO) based PID controller and Genetic Algorithm (GA) based PID controller has been analyzed in order to demonstrate the superior efficiency of the proposed GWO in tuning PID controllers. By comparison with the conventional technique, the effectiveness of the anticipated scheme is confirmed. A three area non reheat thermal system is considered to be equipped with PID controllers. GWO is employed to search for optimal controllers parameters to minimize certain performance index. The UPFC is placed in the tie line for further improvement in system performance.
