Optimal load frequency controller for a deregulated non-reheat thermal power system

Load frequency control (LFC) is a very important issue in the operation and control of power systems for supplying sufficient and reliable electric power with good quality. With deregulation of power system, major changes have been introduced into the structure of the electric power utilities all around the world. In this new framework, consumers are free to make a choice among competing providers of electric power. This paper deals with the modelling and simulation of optimal load frequency control in an interconnected two area non-reheat deregulated power system.
