PID Based Automatic Generation Control of Two Area System

The Power System consists of Power System Generation, Power System Transmission, Power System Distribution and Power System Utilization. Power System plays a vital role in human’s daily lives .Power system has great influences and global impact on how the world operates. For the good performance of the Power System Some control operation are needed at every part. In an Interrelated Electrical System, the load variation occurs, Frequency and tie-line power interchange exhibit a great dissimilarity , in order to get the objective of variance in Electrical frequency and tie-line power flow to zero ,a complementary control action which is used to achieve selected generating units this control action is callled Automatic Generation control .This paper presents Power system analysis, control and methodology for comparing the response at various load values and illuminate the effectiveness of Proportional-integral derivative controller and get results on MATLAB/Simulink and analyze the system stability and system Control.
