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.
