THE STUDY OF DYNAMIC BEHAVIOUR OF INTERLINKEDPOWER SYSTEM USING SIMULINK

Practically all power system is interconnected in nature. In multi area interlinked power system the variation in load is a big obstacle .The basic intent of automatic load frequency control is to maintain total generation of system with total system requirement so that the frequency and the real power exchange with associated system are unaffected. Any dissembling between generated power and the consumed power results variation in system frequency scheduled frequency. The variation in frequency causes the system collapse, so in order to avoid such a problem we have to control the frequency variation in interlinked power system. This paper presents different Simulink results which shows the dynamic behavior of multi area interrelated power system with different conventional controller with 1% step load change, and it is found that these results are improved with the help of optimal control technique i.e. LQR method.
