Load Frequency Control of Single Area Power System using LQG Controller

Abstract

This work depicts the design of LQG controller to get the solution of the load frequency control (LFC) issue of a single area power system. Initially description of each state variable analysis is done and then the LQG method is elaborated for solving the LFC issue in a given plant. The controller performance is verified through comparing the output responses of the same system by different other methods. It is visualized that designed controller exhibit better performance with respect to the other controllers as seen from the output responses in simulation and the comparative analysis is also carried out for both transient and steady state condition.
