Abstract
The paper deals with optimal tuning of a PID controller for a load frequency control of four areas Power system using Firefly algorithm. The proposed approach has superior feature, including easy implementation, stable convergence characteristics and very good computational performances efficiency. The main objective is to obtain a stable, robust and controlled system by tuning the PID controller using Firefly algorithm. The interconnected four area LFC system is modeled and simulated using MATLAB-SIMLINK environment and the PID control parameters are tuned based on FA algorithm. By comparison with the conventional technique, the effectiveness of the anticipated scheme is confirmed. Hence the results establishes that tuning the PID controller using the firefly optimisation technique gives less over shoot, system is less sluggish. Optimization technique finds the best parameters for controller and designed controller are an optimal controller. The simulated results are obtained for different load configurations of the Firefly algorithm based controller and this indicate that the better control performance in terms of overshoot and settling time can be achieved by choosing PID among the other considered classical controllers.
