A Hybrid Optimisation Algorithm for Voltage Control

摘要

This paper proposes of a hybrid optimisation algorithm consisting of the ant-colony optimisation and whale optimisation algorithm for the tuning of PID controllers in AVR systems. Two excitation models are chosen, namely the Type DC1A and Type AC5A excitation systems which are coupled with either a first order or a fourth order generator model. A Proportional Integral Derivative (PID) controller is incorporated into the system to correct the step response in terms of percentage overshoot, settling time and steady state error. The hybrid algorithm is then tested against the individual optimisation schemes and the results obtained were found to be very promising.
