چکیده مقاله :
Low changes in active power demand cause changes in the frequency of the power system. The purpose of using a load frequency control (LFC) system is to maintain the frequency balance in the power system, using active power control to minimize frequency changes to achieve acceptable power system stability. In this paper, the linearized model of a gas power plant has been studied and simulated to check the small signal stability and load frequency control. The frequency depends on the parameters of the power system, and small changes in the parameters cause slight deviations in the frequency of the power system. To provide good quality output power, LFC should have good robustness against uncertainty of power system parameters and sudden changes. The initial order equations of the system in the state space have been used in MATLAB software to simulate the dynamic behavior. The effect of changes in different parameters on frequency deviation and stability of the power system has been investigated. Analysis of system modes show the correctness of the simulation results.
