Four-area power system is prefered for LFC problem in multi area power systems are more complex and important than one area power system. In this paper, LFC problem is defined firstly, and then mathematical models of power systems are explained. Finally PID controller are described shortly and power system is modelled by using MATLAB-Simulink platform.trinfo:eu-repo/semantics/closedAccessConference Object72772-s2.0-79951655579N/A
