Abstract

In a Power system, if the load varies the frequency of the generator also varies. Automatic load frequency control plays a major role in maintaining the frequency constant. Various controllers like PI, PID and 2DOF-PID are used for controlling the load frequency in power system. Two degree of Freedom Controller optimized by Particle Swarm Optimization will help to adjust the generator frequency to ensure stable and efficient response due to sudden changes in load. The single area power system consisting of non-reheat thermal power plants with 2DOF-PID controller has been considered for design and analysis. The gains of the 2DOF-PIDcontroller is optimized by the particle swarm optimization to have a better dynamic performance, to reject the load disturbance , to improve the robustness and also to reduce the Integral Time Absolute Error which is caused due to sudden changes in load demand.
