A performance evaluation of load frequency controller using discrete model predictive controller

Abstract

Load frequency control becomes one of the important parts in a power system since frequency deviation is an important issue in power system stability. This paper has introduced model predictive controller to handle the frequency deviation when disturbance happen. Result of simulation in a three area power system shows that PI controllers have faster response than model predictive controllers, but calculation shows that model predictive controller will have decay faster than PI controllers. On the other hand, model predictive controllers showed better performance and signal processing time which are verified with disturbance variations in long time simulation; therefore it can be a good candidate for a load frequency control.
