Simulation and Modeling of Automatic Generation Control using PI and PID Controller in Deregulated Environment

Automatic Generation Control (AGC), a significant control process, which is responsible for frequency control, power interchange and economic dispatch operates constantly to balance the generation and load in power system at a minimum cost. AGC with control area concept, reflection of disco participation matrix (DPM) in AGC modeling and controller to obtain good output frequency response is studied in this paper. The tuning of PID controller is necessary to get an output with better dynamic and static performance. The output response of PID tuning is compared with PI and found reasonably good over conventional controller
