Abstract: Load Frequency Control (LFC) and Automatic Voltage Control (AVR) are one of the most important issues in electric power systems. Although Proportional-Integral (PI) controllers are commonly used for LFC and AVR systems in industry, they are not able to achieve good dinamic behavior in the presence of various load changes and operating conditions, because PI controller parameters are usually tuned based on classical error approaches . This paper presents a new approach for tuning the appropriate values for the proportional-integral-derivative (PID) controller parameters of the load frequency control (LFC) and the Automatic Voltage Regulator (AVR) systems using the Imperial Competitive Algorithm (ICA). This requires designing a precise and fast controller to preserve the system parameters at a nominal value. The basic purpose of system generation control is to balance system generation against load and losses, in order to preserve the desire frequency and power exchange between neighboring systems. The proposed method shows the application of the ICA method to search the optimal PID controller parameters of LFC and AVR systems. The proposed method had different capability like, easy implementation and good computational efficiency. The results were compared with other evolutional algorithm like SFL and PSO and the advantage of the proposed method was revealed.
