Abstract :
This paper deals with the design of an auxiliary controller using linear quadratic regulator (LQR) and linear quadratic Gaussian (LQG) techniques. A three machine three bus power system equipped with conventional controllers is considered. The system is supplemented with the proposed auxiliary controllers. Using computer simulation it is shown that the proposed controller has increased stability and reliability of the system.
