Frequency Control of Two Region Two-Unit Systems with PDF + (1+PI) Controller

Unpredictable load variation in the power system results a frequency shift and if the variance is significant enough, the process may fail. Due to the growth in dimension and complexity of power infrastructures as well as the increase in power consumption, the use of intelligent systems power systems has become essential so, a better controller is always welcome. In this study, a widely utilized two-zone non-reheat type system is employed to examine the performance of PDF + (1+PI) controller. The Differential Evolution Algorithm is used to set the controller parameters with ITAE serving as the goal function. The system is created in the MATLAB/SIMULINK environment. The result shows that, in comparison to other controllers, the PDF + (1+PI) controller offers greater dynamic response by reducing time needed to settle and undershoots.
