PID Tuning for Three-Area Load Frequency Control Systems

In all electrical power generation systems there is a need to preserve the operating frequency at the desired and nominal value. The change in frequency is due to the change in the load level of the system. This frequency variation can be controlled and regulated using an ALFC. Therefore modeling and designing an appropriate LFC is significant. As a result the primary purpose of this thesis is to explore and propose the appropriate intelligent controller techniques for AGC of mixed thermal-hydropower systems. The thesis can be used as a reference for future studies that can be done on ALFC problems. In addition anyone who is going to implement an intelligent ALFC in different power systems can also use it as a reference. The thesis work can also be used as a basis for further improvement on the ALFC system.
