Analysis of control sensitivity functions for power system frequency regulation

Abstract

This work studies the behavior of the Control Sensitivity Functions derivated from the frequency regulation structure in power systems. Here, we explore the performance of the sensitivity functions in the presence of changes in the parameters of frequency regulation and power system components. A one-area power system is employed as the simulation benchmark. Results of frequency-domain analysis with Bode plots highlight the more significant parameters for Load Frequency Control and the different changes in sensitivity functions.
