Abstract
An expert system's knowledge is obtained from many sources and the code of them written in a form proper for the system to use in its inference or reasoning processes. And the goal of Load Frequency Control is to make changing in the power output of the electric generator in the area to change the system frequency. The LFC used to maintain the system frequency and tie-line power with the other areas within the arranged limits. This paper studies the using of modern tuning technique to control the load frequency in two areas power system using PID controller. By tuning the PID parameters this tuning technique depend on the expert systems. An expert system is a set of program that manipulates encoded knowledge to solve problem in a specialized domain that normally requires human expertise. Once a sufficient body of expert knowledge found, it must be programmed in some form, loaded into a data base, then tested, and refined repeatedly during the system. By using MATLAB/SIMULINK software. The Simulations are done for the two different areas with same parameters of PID. The used method in this paper is Adaptive Acceleration Coefficients based PSO (AACPSO). Then the comparison has been carried out for this method and many methods used in the old study. Therefore, this paper introduce some modern techniques for Load Frequency Control. The proposed techniques based on Artificial Intelligence/technique and expert system. It gives promising results.
