Performance of Load Frequency Control of Two-Area Power System by Using Proportional Integral Derivative Controller

For connected power system to be legitimate and reliable during active power Transmission. The Performance of Automatic Generation Control is essential and the main objective of this load frequency control is to make the frequency constant and also to maintain the power flow of tie line in each and every area during operational process. In this paper two area system is used and PI and PID controllers are applied in the MATLAB/SIMULINK systems. In this paper we have shown the detailed parameters comparison between the twocontroller using PID tuned method which shows the different stages at which controller makes the system stable for smooth and efficient operation can be improved further or verified whether it is correct or need some changes for different applications.
