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 quality 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 turbinegenerators 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 (b) the tie line power to be maintained between specified limits. If the above parameters are maintained with in desired limits the generation control is said to be most effective. The main objective of automatic generation control is to maintain the balance between the generation and demand of a particular power system. A power system model has been simulated within a MATLAB environment. A comparative study between the frequency responses of the system using ANN Based PI Control has been proposed.
