Abstract This paper considers the problem of load frequency control using intelligent controllers. Three types of turbines, namely the non-reheat steam turbine, reheat steam turbine and hydraulic turbine, are considered. Two-area power systems undergoing sudden load changes in each area are implemented and analysed. The objective is to eliminate errors due to the disturbances in both frequency and tie-line power so as to ensure an economic power generation. PID, Fuzzy Logic and ANN-NARMA-L2 compensating schemes are designed and successfully simulated. In all the three cases, steady-state errors present in the systems are removed. The results obtained are promising and show the satisfactory performance of the intelligent controllers in achieving load frequency control.
