Implementation of fuzzy logic controller for load frequency control in two area power system

Rout , Nirakar and Sethy , Jagadish Kumar (2014) Implementation of fuzzy logic controller for load frequency control in two area power system. BTech thesis.



Currently as there has been an increase in the interconnected systems as far as power systems are concerned. Load as well as power flow in tie-line are varying dynamically. So there is a need of robust control of system frequency as well as tie-line power flow system. This robust control could be achieved by the help of fuzzy logic controllers in the place of orthodox system using proportional, PI and PID controllers. This is due to fact that gain constants in the case of conventional controllers remain same throughout, for changes in the load value. But Load can’t be the same throughout, load deviates from time to time. So as to get rid of these disadvantages related to conventional controllers, a lot many schemes have been put forth in literature. With regard to this work, fuzzy logic base controller has been considered for problems pertaining to load frequency control. There queried rules are carried out with respect to the variation in load to diminish the error. In fuzzy logic controller, we take the help of triangular membership function in the formulation of the rule base, because triangular membership function gives easy way to make the rule base compared to other membership functions. Then simulation is done by using Matlab/Simulink software.
