Design of controller to damp inter area oscillations

Abstract

This paper deals with the analysis and simulation of power system operation with an integrated control viz., under single area and two-area control and it was carried out with the help of MATLAB. The simulation studies will enable an easier understanding of the effect of an actual load change and how the frequency and voltage are maintained by introducing state feedback controller. The paper deals with simulated results using MATLAB to show the response of the system like tie-line power, frequency deviation for different torques. The modeling, analysis and simulation has been carried out for a detailed performance evaluation of a real time power system. Such a study has helped in proposing methods to examine the stability of the system. The stability of the system is improved by feedback gain matrix.
