Full order observer based load frequency control of Single Area Power System

In this paper a full-order observer-based optimal control technique is implemented to control the load frequency problem for a single area power system. A state feedback controller is designed using linear quadratic regulator (LQR) and full-order state observer based design techniques. A numerical example is considered to check the capability of the developed methodology. The performance is compared between both the methods. It has been recognized through the simulation results and the tabulated data that the performance of observer based LQR controller is better both in term of transient as well as at steady state performance.
