Adaptive Control Policy Via Switching Controller for Load Frequency Control Using Improved Particle Swarm Optimization

There have been several load frequency control techniques presented and reported up to the present time. Each technique has a unique manner of enhancing the capacity to reject disturbances and the system response. Some approaches are superior in some ways while others are superior in others. Using some of them together may bring better system performance. This research presents an adaptive control scheme for load frequency using a switched controller with improved particle swarm optimization. It will enhance the system's accuracy and performance. According to the control policy, Controller actions can be increased or decreased by giving them different weights during the operation. Two distinct Proportional-integral-derivative controllers from the current era are in use, and they were designed in two different ways. The best features of these two candidate controllers are extracted using adaptive control logic. To verify the accuracy and efficacy of the proposed policy, single-area power system problems are considered.
