Abstract

In recent years, the speed of the growth of electronic devices and switches has been remarkable and widely used for stability and control mechanisms in power system. If the disturbance persists for a long time then the conventional controllers for the LFC alone will not be enough to reduce the inconsistency between demand and production and results in frequency deviation from the nominal value. The proposed solution to overcome this problem is to use a frequency controller in coordination with Facts devices and energy storage systems. System control in emergency conditions and sudden changes of load will be studied and transient stability and system protection will be investigated. The control loop regulates the frequency and the actual power and the load-frequency voltage regulator loop controls the reactive power and voltage size. Accordingly, the frequency controller design is presented to improve the stability and prevent frequency deviations and disturbances in the power system. In this research, the small signal stability of a power network in which the load-frequency controller is in operation with facts and energy storage device is examined. Based on this, a new method using PSO algorithm is presented for optimization of the PID regulator used in a two-area power system as part of a loadfrequency controller in conjunction with a UPFC and energy saving system. The efficiency of the proposed algorithm is proved in comparison with the classical algorithm of Nikles.
