Differential Evolution based Intelligent Control Approach for LFC of Multiarea Power System with Communication Time Delays

This paper spotlights the significance of communication time delays (CTDs) on performance of dual area power system having multi-type generations. Investigation is accomplished by targeting area-1 with variation in step load of 1% perturbation (SLP). Fuzzy-PID (FPID) controller is implemented to regularize the deviations in system performance by utilizing fine tuning approach of differential evolution (DE) subjugated to error squared over integral (ISE) function. However, the performance potency of FPID controller is constituted by comparing with those of PI and PID. Moreover, the effect of CTDs on power system is clearly demonstrated by comparing the responses that are retrieved with and without considering CTDs in the system.
