In this paper work we analyze and design Automatic load frequency control of two areas power system using Genetic Algorithm and also for four area power system using artificial neural network (ANN), generation control is becoming increasingly important in view of increased load demand & reducing generating resources. The increasing load demands are posing serious threats to reliable operation of power systems. As we all that Maintaining power system frequency at constant value is very important for the health of the power generating equipment and the utilization equipment at the customer end. The job of automatic frequency regulation is achieved by governing systems of individual turbine - generators and Automatic Generation Control (AGC) or Load frequency control ( LFC) system of the power system. The healthy and undamaged operation of generator needs the control of the following parameters: (a) Frequency to be maintained constant i.e. at 50 Hz (b) the tie line power to be maintained between spec ified limits. If the above parameters are maintained with in desired limits the generation control is said to be most effective. There are so Many techniques for automatic load frequency control like integral controller, PID controller. The main objecti ve of automatic generation control is to maintain the balance between the generation and demand of a particular power system.
