Abstract

An automatic gain control (AGC) system must maintain an electric energy system at a desired operating level. Linear multivariable control is a suitable tool in this case. It is shown how an LQG (linear quadratic Gaussian) controller can be implemented to an AGC system that uses a proportional-integral (PI) controller. This is demonstrated on a two-area interconnected power system. The LQG controller has the advantage of providing a guaranteed robustness margin as well as tracking performance. Therefore, the system is less sensitive to parameter changes
