Adaptive Firefly Strategies for Load Frequency Controller Design

Abstract

In this dissertation, adaptive firefly strategies have been validated using standard benchmark functions and compared with basic firefly algorithm. Further firefly and adaptive firefly is applied to tune PID parameters for load frequency control in electric power system using approximate model matching technique in frequency domain. The difference between the Nyquist response of the actual and reference model has been considered as the error function to be minimized with the help of the above mentioned algorithm. The results obtained are satisfactory with respect to single area power system and multi area power system networks.
