The present paper investigates the design of Load-Frequency Control ( LFC) system for improving power system dynamic performance over a wide range of operating conditions based on model predtictive control MPC technique. The objectives of load frequency control (LFC) are to minimize the transient deviations in area frequency and tie-line power interchange variables . Also steady state error of the above variaables forced to be zeros. The two control schems namely Fuzzy logic control and proposed model predictive control are designed. Both the two controllers empoly the local frequency deviation signal as input signal. The dynamic model of two-area power system under study is estabilished . To validate the effectiveness of the proposed MPC controller, two-area power system is simulated over a wide range of operating conditions. Further, comparative studies between the fuzzy logic controller (FLC), and the proposed MPC load frequency control are evaluated.
