کنترل کننده های هوشمند برای کنترل فرکانس بار سیستم قدرت دو منطقه

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.
