Colliding Bodies Optimization-based PID Controller for Load Frequency Control of single area power system

In this paper, a novel meta-heuristic Colliding bodies optimization-based proportional-integral-derivative controller with derivative filter is presented to solve a single-area power system's load frequency control issues. The controller parameters are determined by employing the integral of time multiplied absolute error as the fitness function. A single-area non-reheat thermal power system is considered for establishing the efficacy of the proposed method. The robustness of the proposed controller is also ascertained by inserting perturbation in system parameters. It is observed from the simulation results that the proposed method provides improved dynamic performance over the existing methods.
