Load Frequency Control Adaptation Using Artificial Intelligent Techniques for One and Two Different

(LFC) is to regulate the power output of the electric generator within an area in response to changes in system frequency and tie-line loading.Thus the LFC helps in maintaining the scheduled system frequency and tie-line power interchange with the other areas within the prescribed limits. Most LFCs are primarily composed of an integral controller. The integrator gain is set to a level that the compromises between fast transient recovery and low overshoot in the dynamic response of the overall system. This type of controller is slow and does not allow the controller designer to take into account possible changes in operating condition and non-linearities in the generator unit. Moreover, it lacks robustness. This paper studies control of load frequency in two area power system with PID controller. In thi
