Design and performance analysis of adaptive neuro fuzzy controller for load frequency control of multi-power system

This paper presents an adaptive neuro fuzzy (ANFIS) based load frequency control for multi-area non-reheat turbine power system. It can handle the non-linearity of the system and react to situation faster than the conventional controller. The changes in frequency and Tie-line power are subjects be controlled for 3-area power system. The system response with proposed controller is compared to that of with conventional controllers presented in literature. The comparison is carried-out in terms of over-shoot, under-shoot and settling-time of frequency and tie-line power. It is proposed that the intelligent controller (ANFIS) provides encouraging result as compared that of with PID controllers in literature. The robustness of the proposed controller is considered for a wide range of change in load.
